Saving and sowing the seeds of the cup-and-saucer vine, plus a day spent with Plant Heritage
It’s 10pm on the 1st of January, and before going to bed I see that the outer case of the cup-and-saucer vine (Cobaea scandens) seedpod I saved in October is dry and brittle, its four seams parting slightly. The twining flower stem and shrivelled leaves cling to the base of the pod. I gently prise the four curving lobes apart to reveal the treasure within: four chambers comprising satin coated beds of pith on which flattish brown seeds overlap one another, resembling hibernating dormice snuggled together for warmth. As I shake the seeds onto a sheet of kitchen paper they fall easily from their resting place. About 1.5cm long, similar in scale to pumpkin seeds, the plump tan storage area of each seed flattens out to a darker brown wavy margin. Certain that the seeds are thoroughly dry, I pop them into a small plastic clip-lock box.
Fast-forward to early March, and the heated propagator is in play, having already accelerated the germination of tomato and sweet-pea seeds. I station sow the 17 saved seeds into individual seed tray cells and wait. By 19 March every seed has germinated, the seed leaves thrusting upwards on fleshy red speckled stalks. I prick them out into 9cm pots and place them on the shelf above the window in the shed for protection.
Thankfully there have been few frosts and the seedlings have survived. Most of them were sold for £1 each at the plant sale held on Good Friday by my client in Richmond, the proceeds of which were donated to Parkinsons UK. I’ve kept back three plants: one of which I shall grow again on the south-facing fence, once the danger of frost has passed and the others I’ll take to clients looking to clothe a wall or fence this summer, albeit with a half-hardy annual. The plants have now reached a similar stage to the form in which I bought the ‘mother’ plant a year ago at a garden centre in Sherborne, Dorset. The true leaves have developed and measure about 11cm long, with four rich green leaflets arranged in pairs and two tiny ‘stipules’ or outgrowths near the base of the leaf stalk. The leaf stalk ends with a terminal leaflet. I can just see a couple of further leaves unfurling at the junction of the two leaves. When mature, the leaflets end in a tendril with tiny hooks with which it clings to its support.
Once planted in situ, the cup-and-saucer vine, also commonly known as cathedral bell, will spread quickly and the flowers begin to emerge during July. They emerge pale green, maturing to a deep shade of purple. I picked a bunch last August to submit to the Kew Horticultural Society’s annual flower & produce show and was delighted to be awarded third prize in the category of, if I remember rightly, a vase of a single species of annuals.
Like their cousins in the Polemoniaceae, the phlox family, the flowers of the cup-and-saucer vine are fragrant, though the scent is not as pervasive. They originate in Mexico and the genus, Cobaea, was named for Bernabé Cobó (1582-1657), a Spanish Jesuit missionary and writer based in Peru. Cobó’s most notable contribution to botany was to describe the bark of the cinchona tree and its use as a remedy for malarial fever in his Historia del Nuevo Mundo.
In 1875, Charles Darwin made a study of a number of climbing plants, to see how they reacted to the stimuli of light and touch. His findings were published in The movements and habits of climbing plants in 1906, and included his observation of the cup-and-saucer vine. Here he noted the exceptionally long tendrils (11 inches in old money), and their capacity to revolve rapidly, as well as the arrangement of tiny hooks with which they cling to the surface on which they grow. On one tendril, he counted 94 ‘of these beautifully constructed little hooks‘ with the hook at the end of the tendril being ‘formed of a hard, translucent, woody substance, and as sharp as the finest needle‘. He also noted that ‘every part of every branchlet is highly sensitive on all sides to a slight touch, and bends in a few minutes towards the touched side’.
What a remarkable plant this is, which deserves to be better known. It thrived last year in its south-facing position and it’s good to know that when I plant one of the seedlings in late May, it’s a direct descendant of that plant I bought a year ago. I recently heard Carol Klein describing the miracle of raising plants from seed and I couldn’t agree more. Furthermore, it’s sustainable, because you’re not buying a new plant in the inevitable plastic pot, but re-using old pots.
Still on the subject of seeds, a month ago I spent the day volunteering for Plant Heritage, the charity which seeks to ensure the cultivated plants we grow now will be available to future generations for cultural, medical, culinary and aesthetic use. The staff at Stone Pine, the HQ of the charity in the village of Wisley in Surrey, were very welcoming. The office we four volunteers worked in overlooked RHS Wisley though we were too busy sorting and cleaning seeds saved in the Sir Harold Hillier Arboretum to admire the view! The other volunteers were very experienced and it was fascinating to learn how to sift through the piles of seeds, removing chaff and so on. Many of the shrub fruits were challenging to deal with, being large and quite leathery.
I spent the day working through a large heap of Lilium regale seeds, trying to neither sneeze nor laugh too enthusiastically, and risk blowing away the fruits of my labours. The final stage of the process was to decant the seeds into small waxed paper bags and then into brown envelopes ready for labelling. The seed packets will be sold throughout the summer at Plant Heritage events and at garden shows and plant sales, to raise funds for the charity. I plan to return for another day’s volunteering in May and am looking forward to more planty conversation and the opportunity to contribute to the work of such a worthwhile cause.
Reviewing last year through images of the gardens I visited and worked in has emphasised to me how much of my life is occupied with gardens and gardening. And how uplifting it is to be involved in the gardening world on a day to day basis. I’m excited about the year to come, which I plan to make as fulfilling as the one that has just finished. Here’s a summary of the last six months of 2023.
July
Seamus luxuriated on the garden bench in the summer sun whilst at NT Osterley the produce was fattening up beautifully in the vegetable plot in the walled garden. I went to the RHS Hampton Court Palace Garden Festival for the first time in several years to enjoy the show gardens and displays in the marquees. One highlight was the RHS Wildlife Garden designed by Jo Thompson, where the presence of dozens of small skipper butterflies was a testament to the wildlife friendly planting scheme. The assistance dog I captured in the photo was very taken with them too! At Pensford Field the wildflowers flourished and the trustees arranged summer activities including a butterfly talk and a summer picnic, the latter captured by a drone-borne camera. The daylilies and white Verbascums (V. chaixii Album) in the large herbaceous border in my Richmond client’s garden were a joyful sight. Hydrangeas and star jasmine attracted attention away from the parched lawn in another garden, which despite my best efforts has always struggled because of the shade cast and moisture taken by the mature trees in the neighbouring gardens.
August
Extreme heat then a damp start to the month saw off the sweetpeas with powdery mildew, but the rain freshened up the garden and turned it into something of a jungle for Seamus whose obsession with the residents of the pond intensified. My plant of the month was a tall intensely blue salvia (S. patens Guanajuato) which went on to flower well into November, despite an inauspicious start on the sale bench at North Hill Nurseries. Astrantia major also thrived, a seedling from a client’s garden the year before. I saved, then sowed, its seeds at the end of August and now have a dozen or so small plants which I hope will form part of the stock at a client’s charity plant sale in April.
A kind friend took me for a picnic tea at Highclere Castle, the location for Downton Abbey. The towers and turrets of the house rise dramatically from the surrounding parkland and meadows. Like many grand estates, the walled garden is located at some distance from the house. Here the dark greens of the parkland trees give way to colourful herbaceous borders.
From High Victorian style to the simplicity of the Arts & Crafts movement later in the month when I went to Rodmarton Manor and Kelmscott Manor. Inspired by a visit to the Emery Walker House in June, where I noticed a watercolour of Rodmarton, both the house and the garden are elegantly spare in style and very beautiful. William Morris’s spirit pervades Kelmscott Manor which has been lovingly restored by the Society of Antiquaries of London. The house dates from the C16 and is a treasure trove of furniture and textiles collected or designed and made by Morris and his family. This exercise of reviewing the past year has reminded me that both these properties deserve a separate blog post. Watch this space.
I entered some exhibits into The Kew Horticultural Society’s annual Flower & Produce Show on the Bank Holiday weekend and was delighted to receive two second prizes and one third for, respectively, a selection of herbaceous perennials, a single Annabelle hydrangea head and a vase of cup & saucer vine flowers. I’m afraid the produce from the allotment plot did not warrant competition with the high standard of the entries to the show.
September
Audley End in Essex was the venue for BBC Gardeners’ World Autumn fair and the first of these fairs I’ve attended. I went with a fellow freelance local gardener, Liz, and we had a great day chatting to the exhibitors. The palatial mansion formed an elegant backdrop to the show and I particularly liked a ‘dry’ show garden where sun-loving plants were planted into a substrate topped with pebbles, larger rounded stones providing variation in height and texture. Back at the allotment, my plot yielded a good crop of potatoes and in a client’s garden I was very happy to see how well my pot planting scheme had turned out. Zonal pelargoniums, Mexican fleabane (Erigeron karvinskianus), purple nemesia and Senecio cineraria ‘Silver Dust’ made for a generous and colourful display. At the rear of the same garden, Rudbeckia Goldsturm fulfilled the client’s brief for a bright colour scheme.
The splendid Lords’ Robing Room in the Palace of Westminster was the location for a recording of Radio 4’s Gardeners’ Question Time for which I was fortunate to get free tickets through BBC shows and tours. The show was eventually aired in November, to coincide with the publication of a report into the state of the UK’s horticulture industry by the House of Lords’ Horticultural Sector Committee. It was fascinating to see the show being recorded and to hear the answers by the panel (Matthew Wilson, Dr Chris Thorogood and Christine Walkden) to the audience questions. At home, the China rose Rosa mutabilis which I’d planted in a large pot earlier in the summer, was awash with flowers, the lax petals ranging from pale lemon to watery pink. Caryopteris clandonensis proved once again to be the best flowering shrub at this time of year for attracting pollinators. We revelled in Tom Hart Dyke’s zest for the exotic specimens in his care in The World Garden at Lullingstone Castle when he welcomed a group of us from the Garden Media Guild.
Having heard Xa Tollemache speak at the Garden Museum in 2022 about A Garden Well Placed, her account of creating the garden at Helmingham Hall near Woodbridge in Suffolk, and how doing so inspired to become a professional garden designer, it was good to visit the place where her career began. The exuberantly planted walled garden complements the moated Elizabethan house which resembles something from a fairytale.
October
Giving a talk about wildlife gardening to the friends of Pensford Field conservation area was great fun and I’ve recently been invited back (in May) when I’ll be taking about adapting our gardens and gardening practices to the changing climate. Reading the biography of Ellen Willmott led to visiting Kingston Water Gardens when they opened for the NGS.
On the last day of the month I went to Leonardslee Lakes & Gardens in West Sussex to admire the autumn foliage reflected in the seven lakes which run through the landscaped estate. Sitting in the bird hide beside one of the lakes, we saw a female Sika deer and her fawn tread gently in front of us whilst we held our breath and savoured the magical experience. I was charmed too by the delightful scenes of Edwardian country life in the village and at the big house, captured in the 1:12 scale models in the ‘Beyond the Dolls’ House’ exhibition. The dense tapestry of planting almost obscures the Pulhamite stone structures which form the basis of the Rock Garden created in 1900. I was particularly interested to see this artificial material again, having so recently been to the Kingston Water Gardens where it was used for the area around the Fernery. Leonardslee is one of the three Sussex gardens associated with the Loder family.
The Loder family boasted many gifted gardeners. Combined, they founded three significant gardens in Sussex, passing down a love of plants and botany throughout generations.
Royal Botanic Gardens, Kew website
Leonardslee is the creation of Sir Edmund Loder. His father Sir Robert started the garden at High Beeches which was further developed by brother Wilfrid and his son Giles. Another brother, Sir Edmund Loder, bought the Wakehurst estate in 1902, administered by Royal Botanic Gardens, Kew and home to part of its living collection of rare plants.
November
As we hurtled towards Christmas, there was still a surprising amount of colour evident in the garden at NT Osterley, due no doubt to the mild weather which characterised last autumn. On 17 November, two salvias shone out in the long border of the walled garden: Salvia Amistad and S. confertiflora. Earlier in the month the alluring but poisonous Aconitum napellus dominated a bed near the Garden House in Mrs Child’s Flower Garden. Visiting a friend in Oundle, Northants I couldn’t resist being photographed outside a houseplant shop whose strapline echoes my own sentiments. At home, Rosa Sceptr’d Isle flowered until late in the month and one afternoon the garden was illuminated by a rainbow which arced over the scarlet hips of Rosa Rambling Rector. We spent a morning planting bulbs in Pensford Field (snowdrops, native daffodils, snakehead fritillaries, wood anemones) and admired the autumnal tints ringing the wildlife pond.
December
Visiting family in south Somerset, I went to NT Montacute House and marvelled at the monumental cloud-pruned yews. As ever, the final garden visit of the year was to Christmas at Kew, where the lit trail didn’t disappoint.
With the start of the year dominated by domestic issues around a boiler failure and kitchen refurbishment, publication of this blog has taken far longer than intended. As I write this on a chilly February evening, I know that in the darkness outside, spring bulbs are nosing yup through the soil. Late last evening, I opened the back door and beyond the welcome sound of heavy rain (it’s been bone dry for a few weeks), I detected frogs croaking their welcome to the season to come.
With only a day and a bit of the old year to go, it seems timely to review my horticultural year: in my own garden, in my clients’ gardens and when visiting gardens and shows. So, rattling through, month by month, here goes with the first six months of the year.
January
After Christmas at Kew on the evening of New Year’s Day, it was time to admire the gardens by day, particularly the newly planted winter garden. I popped back yesterday morning to see that the plants in this image from a year ago have filled out considerably. Fridays mornings at NT Osterley were sunny and crisp, the ghost bramble in the Garden House an unusual addition to the winter display. Back at Kew, I did a couple of ‘mossing’ sessions in the Princess of Wales Conservatory to prepare for the February orchid festival themed around Cameroon. Temperatures stayed below freezing for several days at the end of the month, making life difficult for these Egyptian geese at the pond on Kew Green. In my clients’ gardens, I applied mulch and found a way to rescue a broken Whichford pot with wallflowers. Garden reading: The Jewel Garden by Monty and Sarah Don reveals the hard work and hard times behind the Long Meadow of today.
February
At NT Osterley and East Lambrook Manor Gardens carpets of Crocus tommasianus heralded spring, whilst in my garden the watermelon pink of the flowering quince (Chaenomeles x superba Pink Lady) brought colour to an otherwise drab palette. On the feline front cheeky Seamus was caught posing beside the pansies on my neighbours’ front windowsill and a magnificent lion with a mane of colourful orchids roared out from the centrepiece of the festival display at RBG, Kew. The sunlight highlighted the trunks of the cherry trees (Prunus serrula) in the winter garden at Sir Harold Hillier Arboretum and Gardens. The Garden Press Event at the Business Design Centre in Islington was both sociable and informative, introducing new products and trends to the gardening media fraternity. A kind friend allowed me to use two plots on her allotment this year where I’ve grown potatoes and chard successfully and cauliflower and lettuce rather less successfully! I’ve sadly had to concede that there aren’t enough hours in the day to cope properly with a veg plot elsewhere and have decided not to proceed with it in 2024. In this image I’m making a fuss of working cocker spaniel Molly before mulching one of the beds with cardboard and well-rotted horse manure in preparation for adopting the no-dig system.
March
A gardening challenge this year has been to enliven the third ‘room’ of a client’s garden with woodland style planting beneath the silver birches. As the year has progressed I’ve introduced Brunnera macrophylla: both the species and Jack Frost and have planted dozens of Scilla sibirica and Tete-a-tete daffodils. More daffodils feature in this posed shot of Seamus in his favourite lookout spot, tail curled nonchalantly beneath the window ledge. I used the image during a one day CityLit course in cyanotype printing later in the month. I enjoyed refreshing a narrow Kew front garden by adding Nandina domestica Lemon and Lime between three Rosa Bonica plants which went on to flower profusely (and pinkly) throughout the summer. As the month wore on, I photographed the daffodils naturalised at NT Osterley between the walled garden and the rear of the Garden House, in my garden and amidst the hellebores in the terraced woodland border at my Monday morning client’s garden near Richmond Green. The annual carpet of scillas in front of Kew Palace and a pot of Scilla bifolia lend a blue note to the end of the month.
April
Parks and gardens style it might be, but the formal planting in St James’s Park on 2 April was stunning. Later that day I began chitting the seed potatoes and it was warm enough the next morning for Seamus to recline beside the pond. The stately stone pine, Pinus pinea, on the south west side of Richmond Green was stop 4 on the trail of Richmond’s Trees which a friend and I followed using the book of that name published in November 2022. I greeted the arrival of tulip season using my new Canon compact camera, in time for a mid month expedition to RHS Bridgewater in the rain (more tulips) and the next day a drier Piet Oudolf planting at the Trentham Estate (fritillary close-up). Back home I explored the Fulham Palace Walled Garden and admired the naturalised tulips beneath the cherries near Kew’s Davies Exploration House before walking down to the natural area of the Gardens to see, smell and photograph the bluebells. For the first time I tried a winter/spring windowbox combination of Bellis perennis and daffodils, the latter being rather longer stemmed than I’d anticipated. I’ve gone for a similar theme this year, with Narcissus ‘Golden Bells’ which I hope will be daintier. I noticed today that they are already nosing through and the first of the daisy flowers has emerged. Barely a week after the trip north I headed to East Sussex to see the tulips at Sarah Raven’s Perch Hill where the delicate shades of the glass bud vases in the shop caught my eye as did a pink themed tulip container featuring Merlot and Flaming Flag. The next day at NT Osterley we all donned protective headgear and fed the heavy duty shredder with rhododendron prunings, the resulting material which we later used to replenish the surface of the path through the winter garden. I completed the month with a garden rich stay in Cornwall’s Roseland peninsula, amply documented in the pages of this blog. On returning home on the last day of the month, the garden rewarded me with wisteria, sweet rocket about to bloom (Hesperis matronalis) and pots of tulips.
May
Having spent much of April either away or out for the day on garden visits, I caught up with client work including mowing in this Richmond garden. The bluebells in Kew were a joy as ever. I always look out for the deep rosy flowers of this special chestnut in Mrs Child’s garden at NT Osterley where the pots beside the entrance to the walled garden overflowed with a red white and blue combination: I forgot to ask whether it was to mark the Coronation on 6 May. Before standing to marshal for Richmond Ranelagh running club’s half marathon, I sneaked a peek at the nearby garden dedicated to Alexander Pope located beside the river in Twickenham. The pale yellow of Mrs Banks’ rose were a gentle backdrop for alliums and forget-me-nots and a cheeky squirrel posed on one of the elegant benches inscribed with quotations from Pope. At home, Seamus relaxed on the damp soil and I photographed the Ballerina tulips. April showers threatened my client’s fundraising plant sale for the Red Cross but we succeeded in selling most of the stock, all raised from seed or cuttings by Gill plus a few plants from cuttings or divisions from my garden. The car boot was brimful after a plant buying morning at North Hill Nurseries, stocking up for clients. Stood in crates through its central path, the new stock made my garden look especially full and verdant. It was great to be back volunteering in Pensford Field on a Saturday morning weeding around the base of the fruit trees and anticipating the flowering of the wildflower meadow as well as enjoying a talk by the beekeepers who passed around a comb and wax cells from the hives. At NT Hinton Ampner in Hampshire I noticed a china rose in flower very like my own Bengal Crimson, a precious purchase from Great Dixter a few years ago. In the Rock Garden at RBG, Kew a Ceanothus cascades over an arch. Eliza Doolittle clothed in moss greets visitors en route to the Chelsea Flower Show. Back at NT Osterley, head gardener Andy Eddy chats with fellow volunteers beside the abut to be planted vegetable bed in the walled garden, irises framing the walkway at the end of the cutting garden. By 26 May my garden is burgeoning, watched over by one of my precious metal hens. I returned to the gardens on Kew Green open for the NGS (white alliums) and Ramster Garden near Godalming (candelabra primroses) before ending the month with a session at a client’s garden where the Geum, Lychnis and Nandina I planted the previous November were holding their own alongside a beautiful pink rose.
June
I visited three historic gardens in June: Luton Hoo Walled Garden, Long Barn and Upton Grey, the last of which is to be the subject of a blog post early in 2024. For the last 20 years the owners of this property in north Hampshire have devoted their time to restoring the garden using Gertrude Jekyll’s original planting plans. The sight of the red-roofed house rising up behind a generously planted herbaceous border reminded me of one of the classic views of Great Dixter. At Pensford Field the wildflower meadow was at full throttle, the oxeye daisies dominating for a few weeks. In the garden at home, the roses revelled in the warm sunshine as did Seamus and the sweetpeas were a temporary triumph until powdery mildew set in a few weeks later. Every year, on the Tuesday closest to midsummer evening, my group at the running club undertakes the Richmond Park ponds run, with the aim of finding as many of the park’s 21 (I think) ponds as possible. It was a warm’ limpid evening and we found more than half the ponds before dusk defeated us. In a client’s garden my planting from the year before in a shady corner had filled out and improved the appearance of a problem area. The Garden House planting at NT Osterley this summer was vibrant and fragrant, featuring lilies and pelargoniums. I was impressed with the bold modern planting in a garden opened for the NGS in East Sheen, grasses softening the structure given by evergreen balls along the border’s edge where it met the lawn.

We humans like sorting things into categories: even when doing the laundry and the washing up. We separate socks from T-shirts and put knives, forks & spoons into the correct compartments of the cutlery drawer. I guess it’s our way of exerting some control in what sometimes feels like a chaotic world. Horticulture and botany excel in sorting. Botanists classify plants into families, genuses (genii?) and species. Gardeners divide them into trees, shrubs, herbaceous perennials, biennials and annuals, with sub-categories for plants thriving in particular soils or in certain aspects: sunny or shaded, dry or boggy. I could go on ad infinitum: herbs, grasses, succulents…..
Nowhere is the horticultural imperative to sort plants into categories more manifest than in a botanical garden. Traditionally these consist of sometimes dozens of rectangular order beds where plants of a particular family or genus are massed together forming a living textbook for study by professional and amateurs alike. I’m thinking here of the botanical gardens in Edinburgh, Oxford, Cambridge and the Chelsea Physic Garden. And, until a few years ago, The Royal Botanic Gardens, Kew. The Order Beds in the northern section of the Gardens were replaced in 2019 by the Agius Evolution Garden, where those rectangles were transformed into sinuous curved ‘rooms’ containing plants of species and families linked by evolutionary connections revealed by DNA research.
On 14 September this year I went with other members of the Garden Media Guild to a botanical garden in Kent created less than 25 years ago, where a map of the world informs the horticultural sorting. This is the World Garden at Lullingstone Garden near Eynsford in Kent, the creation of plant explorer Tom Hart Dyke within an existing one acre walled garden* and one acre of polytunnels. A world map is set into the walled garden, the continents containing ‘phyto-geographically’ categorised species, the borders against each perimeter wall housing hybrids and cultivars. Tom was our hugely enthusiastic guide around this unique garden, generously spending the morning with us and regaling us with fascinating facts about the many rare species featured in the garden.
This is a remarkable garden for many reasons. It’s been made with a small budget, 92% of the plant material having been donated, often raised from cuttings and small plants. The ‘continents’ are landscaped with rocks from the British Isles, but chosen because their geology mirrors that of the continent featured. Where appropriate, Lullingstone’s flinty alkaline soil has been replaced with acidic soil sourced from glacial deposits near Wisley in Surrey.
But perhaps the most remarkable fact about the World Garden is that when Tom had the idea for it he didn’t know if he would live to see his beloved Lullingstone Castle again let alone make the garden of his dreams there. In 2000, whilst on a orchid hunting trip to Central America, he and fellow adventurer Paul Winder were kidnapped and imprisoned by guerillas when crossing the notorious Darien Gap between Panama and Colombia. Tom made very light of his ordeal in the introduction to his tour, but I’ve been reading The Cloud Garden (2003), his and Paul’s account of their 9 month captivity, which reveals the desperately dangerous and terrifying nature of their situation during that period.
After being kidnapped a day or so after beginning their 66 mile trek to the Colombian border, they were forced to move between several encampments, trekking many miles through the thickly forested mountain terrain. They often spent several weeks in each camp, some of which were located in the cloud forest where Tom found relief from the oppression of his circumstances when he found immensely rare orchids growing in profusion. Bizarrely his captors would occasionally allow him to wander from the camp to collect these epiphytic plants which he brought back to camp and displayed on a makeshift luggage rack he had fashioned out of cut branches. When the time came to decamp, he was forced to abandon his living collection of rare species which would have been the envy of many an orchid specialist.
Their captors changed leader several times during the nine months, as did the armed guards in the camps, some reappearing after a few weeks. Despite their protestations, the kidnappers believed that the pair came from wealthy families able to afford million dollar ransoms for their release. Or that they were CIA operatives intent on foiling the exploits of the drug cartels operating in the area. Between gruelling interrogations, Tom and Paul found solace in playing draughts with pieces hand carved by Paul or teaching the guards to sing ‘Always Look on the Bright Side of Life’! Their good humour and resilience saw them through dark times of illness induced by poor food and parasites, as well as the terrifying uncertainty of their circumstances.
The pair were held from February until being freed shortly before Christmas 2000, having endured many months of deprivation. They never established for certain who their captors were, though they were thought to be guerrillas belonging to FARC, the anti-government armed militia with whom the Colombian government reached a peace deal in 2016. Tom has written about the building of the World Garden and his plant-hunting exploits in An Englishman’s Home: Adventures of an Eccentric Gardener (2007).
Starting his tour near the crenellated gatehouse built in 1493, Tom introduced us to the rare conifers planted between the house itself and the walled garden. I think this photograph captures something of his infectious enthusiasm for the plants in his care. In all there are 450 different species of tree at Lullingstone.
A series of island beds, approximately 3m across, planted with about 500 dahlia cultivars, draw the visitor towards the moon gated entrance to the World Garden.
Our first stop in the World Garden was Asia where we saw species from across the continent, before moving to Australia to admire a Eucalyptus volcanica, one of the specimens which make up the National Collection of Eucalyptus of which Tom is the registered curator. Mexican plants, including a tree Dahlia from the cloud forest region, enjoy a south-facing aspect. Protection against winter cold takes the form of a polytunnel about 18 metres long and over a metre wide.
I was fascinated by the use of a coal mulch on the South American bed to protect many tender plants from slugs and snails. I’ve not come across this material being used in this way before.
Pots of aeoniums are embedded into soil and dug up and protected under cover during the winter. The south-facing border provides the right place for numerous salvias, Helianthus, and South American Dahlias such as species Dahlia Dahlia merkii.
I am now going to let the photographs do the talking. Sadly I didn’t photograph all the plant names so a few of the plants featured are unidentifiable.
The anti-burglar plant Colletia histrix, also hails from South America.
The following images of a Begonia, Pelargonium and spectacular cacti were taken in the polytunnels.
Tom and his small team run a nursery shop stocked with plants raised at Lullingstone. A beautiful garden in its own right, few of us could resist the temptation of buying a souvenir of a memorable visit to this unique place. I treated myself to a pretty light purple Salvia Lavender Dilly Dilly, destined for new resilient planting in the front garden, a project I plan to progress and document here in the coming months. Also a green tinged Aeonium Velour, now getting VIP over-wintering treatment on the shelf in the spare bedroom. I feel a responsibility to nurture these two plants, given that Tom mentioned them both when signing my copy of his book!
How much the poorer the horticultural world would be had the kidnappers not freed their prisoners 23 years ago. Tom Hart Dyke’s vision of a garden encompassing unique specimens from across the globe would never have seen the light of day, a garden which has put Lullingstone Castle well and truly on the map for all plant lovers.
Kew Gardens, 3 December 2023
*The walled garden was formerly home to the white mulberry bushes (Morus alba) for the Lullingstone Silk Farm set up by Tom’s grandmother Lady Zoe Hart Dyke. Silk produced by the farm was used for the late Queen’s wedding dress in 1947 and her coronation dress in 1953. I love the fact that until the operation of the farm moved to Hertfordshire in 1956, hundreds of thousands of silkworms were bred in 30 rooms in the house where they grazed on the leaves of the mulberries.

What follows is a summary of a talk I gave on 14 October to the Friends of Pensford Field, a conservation project here in Kew.
A garden doesn’t have to be a wilderness in order to be a haven for wildlife. I’ll detail the key components for a wildlife friendly garden, and argue this isn’t merely a trend, but that it’s vital that we all take steps to maintain and hopefully increase the biodiversity in our gardens.
Biodiversity loss is increasing at an alarming rate: Since 2004 the insect population in these islands has decreased by 64%. In the State of Nature report issued in the last week of September, it was stated that 1 in 6 of 10,000 species assessed is at risk of being lost from the British Isles, with a far higher figure for birds. In the January 2023 Big Garden Birdwatch the sighting of sparrows, song thrushes and skylarks was down again as it had been the year before.
Gardens are said to occupy more landspace than all Britain’s conservation areas and nature reserves combined, so re-wilded gardens could create important wildlife corridors between fragmented woodlands, meadows and other wild habitats.
As a gardener, my instinct is to keep the garden looking neat and tidy so surely making it wildlife friendly will mean sacrificing that sharp-edged smartness for something resembling a jungle? Not at all, you can for example devote a small area of the garden to a ‘re-wilded’ area where the grass is longer, there are woodpiles and wildflowers, perhaps a pond or a bog garden and after a while, the place will be buzzing with insect and amphibian life. This doesn’t mean that the rest of the garden should still need treating with pesticides and herbicides: if you get the balance right pesticides won’t be needed because birds and invertebrate predators like solitary wasps will have seen off the destructive bugs. As for weedkillers, there’s nothing like a session of intensive hand weeding to clear the mind, relieve stress and achieve attractive results without the equivalent of that scorched earth effect when the poison has done its stuff and the weeds have turned to an unsightly brown crispy mess.
What are the fundamental elements of a wildlife friendly garden? If you think about the three things we all need to function the same applies to garden wildlife: shelter, water and food. Dealing with each of these in turn:
SHELTER
Imagine micro versions of the habitats that wildlife thrives in: woodlands, meadows and wetlands.
Trees: You might already have a tree in your garden which shelters many different organisms, both at the invertebrate level as well as larger creatures like birds and squirrels. If you possibly can do introduce a tree into your garden. Many trees are well suited to smaller gardens and there are cultivars that have a narrow growing habit rather than having wide spreading branches. Examples are Prunus Amonagowa and Amelanchier Ballerina: both are deciduous but with interest in all seasons with spring blossom, fruits attractive to birds in late summer and attractive autumn foliage. Use the height and protection offered by the tree to install bird nesting boxes or open-bottomed bat boxes. Bear in mind that brand new boxes are usually made from treated wood which will smell of the chemicals used to preserve the wood (do also make sure that the product you buy is made from wood from sustainable sources). Birds and bats prefer to wait for a season or two until the box has weathered before setting up home. A bat box has an open bottom for the roosting bat to fly up into and needs to be fixed as high as possible, say at least 2 metres. Bird boxes must be sited away from potential danger points, such as fencing where a determined cat is likely to be able to take a swipe at a parent flying in or out while feeding a brood or indeed a fledgling leaving the nest for the first time.
Log piles: Piles of rotting wood in the form of log piles or stacks of brash, such as the prunings from a renovation prune of a favourite shrub, can be placed in shady corners to accommodate myriad invertebrates, including stag beetles. Despite their scary appearance and erratic bumbling flight, these fascinating animals are garden friends and by feeding on rotting wood the larvae help to keep our gardens tidy. The adults live for a few weeks of the summer and when seen on the wing are likely to be in search of a mate. Their distribution is confined to the southern counties with the highest concentration recorded in the south east. They are classed as endangered in many European countries and indeed have gone extinct in Denmark and Latvia. If you have to have a tree cut down for some reason, do not have the stump ground down but leave it to decay naturally where it will provide a des. res. for stag beetle larvae. If the stump looks unsightly in the centre of a bed or border, plant herbaceous perennials around it to grow up around it each spring and summer and hide the stump. Amphibians such as frogs, toads and newts will favour log piles for over-wintering. They also like to shelter in compost heaps, leaf litter, and spaces under sheds or greenhouses and decking: somewhere damp and protected. Their bodies need to be allowed to enter a period of low metabolic function to help them survive the cold. You don’t have to have a pond to attract amphibians (although a pond is a wonderful addition to a wildlife friendly garden as I shall go on to demonstrate). As long as there is dense planting rich in insect life for hunting which provides a damp hideaway, amphibians can reach other nearby ponds.
Bug hotels are another fantastic way to provide shelter for invertebrates in your garden and there’s a splendid example of one at Pensford Field. They’ve also become a popular garden accessory and can be bought off the shelf, though they’re not quite the same as creating one out of a log drilled with varying sizes of holes and stuffed with hollow stems for solitary bees and wasps. A commercially made bug hotel, like the bird and bat boxes, might smell and feel rather new and strange so may take a while to be occupied. There are houses for solitary bumble bees in the kitchen garden at Kew Gardens.
Long grass/meadows: Since the 1970s we’ve lost a shocking 97% of flower rich meadows in this country. The No Mow May campaign has been running now for a few years, started by Plantlife, the charity which aims to protect the vital habitats which so many creatures call home. The purpose of the campaign is to encourage gardeners and green space managers not to mow during May, thereby creating a space for nature. Long grass shelters many species of insect, grass hoppers included, and is a vital habitat to support their life cycles. If you do decide at the end of the month of May that you want to make the lawn look more Wimbledon Centre Court than Serengeti, there are a few things you can do to protect wildlife as you mow.
Before starting to cut, hand search longer grass areas for small mammals like hedgehogs.
For the first cut, set the blades as high as possible, and mow strips only half as wide as the mower to reduce the load on the mower.
Don’t mow around the edges to the centre, as this prevents the creatures which have adopted this area as home from escaping towards the uncut section of grass.
As you mow progress gradually towards sanctuary areas such as uncut grass strips at boundaries.
Let it Bloom June allows the lawn wildflowers which began to emerge in May to bloom by extending No Mow May into June and making part of the garden a wildflower landscape: encourage an area of lawn to be left as a flowering lawn to be mown once every 4 to 8 weeks during the growing season. Common low growing plants will re-grow and re-flower throughout the summer after a cut to maintain a shorter, neater height: red and white clovers, golden trefoils, blue self heal and white yarrow. Even in a period of drought, when the grasses fall dormant and go brown, the wildflowers remain green.
You can go one step further by mowing only twice a year avoiding the period from April to July. This enables you to recreate the effect of a traditional hay meadow. Taller flowers like red campions, purple knapweeds and mauve scabious will thrive. Treat an area like this as a perennial herbaceous border you never need to feed or water: by leaving it undisturbed for longer, the wildflowers and grasses will support the lifecycles of the invertebrates which depend on them.
By leaving some grass permanently unmowed, it won’t support as many wildflowers but will provide a sanctuary for wildlife in hot summers and cold winters: this could be a sanctuary strip at the base of a hedge or fence for toads and voles with seed heads acting as natural bird feeders for finches. This is low maintenance gardening with the only management being to snip out woody saplings or over-vigorous brambles.
When you do cut the meadowed area, it is advisable to collect and rake off cuttings : leave them for a day or so to dry and for invertebrates to escape. This prevents a build-up which might inhibit the re-growth of wildflowers and no cuttings rotting down into the soil means less soil fertility. The more fertile the soil the better the grass will grow at the expense of wildflowers. A further advantage of a wilder lawn is that it captures and locks away more carbon helping you to do your bit for the climate. In the next section I look at creating a wildflower meadow from scratch.

FOOD
Soil dwellers: When you’re planning a garden that will provide food for the creatures you want to attract, it helps to start at the bottom of the food chain with the invertebrates and other creatures and organisms which occupy the soil in your garden. We are constantly being told by gardening pundits to enrich our soil with organic matter. Not only does this improve the structure of the soil (particularly important here in Kew where we have very sandy soil from which nutrients are easily washed away), it provides fodder for the soil fauna like earthworms, mites, nematodes, springtails, ants etc. that spend much of their life underground. These in turn feed burrowing rodents like moles as well as omnivorous birds such as robins and blackbirds. You can mulch the garden with garden compost you’ve made yourself in a home compost heap or bin or with a number of media which will bulk up sandy soil or open out the structure of clay based soil. Examples are spent mushroom compost, composted bark fines or well-rotted farmyard manure. The best time to apply such mulches is in late winter just as spring bulbs and last year’s herbaceous perennials are nosing through so you can work around them rather than submerging them. As well as helping the underground creatures, your garden plants will thank you too as such mulches help to conserve moisture in the soil and feed the plants for the rest of the season.
Butterflies: Moving up the food chain brings us to the larvae of the butterflies and moths which when full grown will help to pollinate many of the flowers and food plants we grow. It’s easy to forget that a beautiful peacock butterfly was once a plump caterpillar. Caterpillars are also a favourite food of many bird species and invertebrates such as solitary wasps. A bluetit chick can eat as many as 100 caterpillars a day. In a fascinating butterfly talk and walk at Pensford in July the supervisor of Kew’s natural habitat areas, highlighted a number of plants which are particular favourites of certain species of butterfly:
Brimstone caterpillars feed on buckthorn.
White species of butterfly famously eat brassicas but as they also like nasturtiums these can be planted alongside as a sacrificial plant to distract the caterpillars from your cabbages.
Tortoiseshells feed on stinging nettles.
As well as holly, holly blue butterfly caterpillars feed on ivy and brambles
Meadow browns and small skippers feed on grasses
Thistles are also good caterpillar food plants. If possible, leave an area in a sunny corner of the garden as a caterpillar larder for some of these plants to thrive. The results of the Big Butterfly Count this summer organised by Butterfly Conservation published in September revealed the great news that butterfly numbers increased this summer compared to the last four summers, though sadly many species have been shown to be in decline since the count started 13 years ago. This year’s mixed weather meant there was an abundance of green food plants for caterpillars and nectar-rich flowers for adult butterflies. The most successful species were red admirals, gatekeepers and holly blues. Since it is habitat loss which causes species to decline, it’s all the more important that we create wild spaces in our gardens for butterflies to feed, breed and shelter.

Pollinating insects: Choosing nectar-rich plants is easy these days when many garden centres use special labelling to highlight ‘plants for pollinators’ using a bee logo to reinforce the message. The important thing to remember is that the flowers you choose give insects easy access to the sweet nectar at the base of the flower and enable the pollinating insect almost incidentally to brush against the male pollen-bearing stamens and transfer the pollen to the female organ, the stigma. This can mean for example:
Open, single-flowers are easy for flying insects to access: the petals are arranged as a guide, directing the pollinators to the centre of the bloom where the nectar is found. Think of daisies where the petals arranged around a central disc guide the insect to the bectar via the pollen. With dahlias, the slim-petalled ‘Honka’ dahlias or the ‘Bishop’ series like the dark-leaved, scarlet flowered Bishop of Llandaff are more likely to appeal to flying insect pollinators than the big showy blooms of dahlias like fashionable Cafe au Lait. Roses are another popular flower where we all fall for the multi-petalled beauties promoted by the likes of David Austin Roses. For a wildlife friendly garden choose a single-flowered china rose like the multi-coloured Rosa mutabilis, the deep red Bengal Crimson or the white climber White Star.
Flowers with a wide landing platform (technically known as an umbel) where the flower heads consist of dozens of tiny flowers arranged in a plate-like structure. These include members of the carrot family such as fennel or sweet cicely, the succulent Hylotelephium (formerly Sedum) spectabile also known as the ice-plant or several members of the daisy family such as Achilleas. A. Goldsturm is a deep yellow cultivar which is very popular and looks particularly good in the borders either side of Kew’s Great Broad Walk.
Flowers with a landing strip often highlighted with markings on the petals at the entrance to a tube or trumpet leading to the nectaries. Think of the spots near the lip of foxglove flowers or the wide apron like lower petal of salvia flowers.
‘Thistle’ like flowers attract pollinators. Examples include the globe thistle, Echinops ritro ‘Veitch’s Blue’ or the crimson Cirsium rivulare ‘Atropurpureum’ which featured a lot at this year’s Chelsea Flower Show. Also teasels and cardoons.
Spires of flowers are popular with pollinators: I’m thinking of Veronicastrum virginicum ‘Fascination’ from North America or the various cultivars of loosestrife, Lythrum salicaria, whose nectar and pollen rich flowers are a hit with bees, butterflies and moths.
Verbena bonariensis, has become a garden staple over the last few years and is a good flower for the hummingbird hawk moth whose long proboscis is able to feed on the nectar at the base of the tiny tubular flowers which make up the purple flowerheads.
Early and late flowers: Many of the flowers I’ve listed so far bloom through the summer months but let’s not forget the early months of the year when some of the early emerging pollinators are foraging for sustenance. This is where the early spring bulbs like snowdrops, scillas and crocus are important. And if you choose carefully from the bulb catalogues advertising their wares at this time of year, you’ll find varieties of Narcissus (daffodil) covering February all the way through to April, when some of the herbaceous perennials start to flower in earnest. Late sources of nectar are important too, and the creamy globe-shaped flowerheads of mature ivy are perfect for providing nourishment in October and November.

Flowering shrubs. The many forms of flowering shrub provide nectar. An obvious example is lavender, but early in the year Forsythia flowers are good, followed by Buddleia which if you keep deadheading them will flower well into September and are called the butterfly bush for good reason. In the last few weeks of Sepember I revelled in the bright blue spiky flowers of deciduous shrub Caryopteris x clandonensis which plays host to dozens of solitary bees, hoverflies and honey bees. A useful evergreen shrub for pollinating insects is Abelia.
BuddleiaCaryopteris clandonensisCaryopteris
Establishing a wildflower meadow I promised earlier to return to wildflower lawns and meadows. I’m including this topic when considering the food that will attract wildlife to the garden because the flowers that thrive in this kind of habitat are usually rich in nectar for flying insects. You can supplement the naturally occurring flowering wildflowers you find in lawns (aka weeds! like plantains and dandelions) with a wider range of meadow plants. either by sowing a wildflower mix of seeds, planting individual plug plants or installing a square or strip of wildflower turf as has been done here at Pensford. If you decide to make a meadow on bare soil don’t be tempted to enrich the soil with fertiliser, the poorer the soil the better. And dig out all perennial weeds like nettles and docks! Nurture these instead in the area you’ve set aside as a caterpillar larder. Let the area rest for a few weeks before sowing or planting, so that any ephemeral weeds can be hoed off and the soil raked, levelled and firmed lightly with penguin steps.
Seeds. Broadcasting a packet or packets of seeds is the cheapest method of making a meadow. The seed companies produce mixes to attract particular creatures (eg. pollinating insects, birds) and it’s a question also of whether you want to make an annual or a perennial wildflower meadow. An annual mixture of seeds consists of colourful cornfield annuals like cornflowers, field poppies, corn marigolds and corncockles which will distribute their seed at the end of the season and produce flowers the following year although further sowings may be needed. Other mixes contain the seeds of perennial meadow plants. These can take longer to establish and might include ox-eye daisies, ragged robin, red campion, knapweed and field scabious. The best time to sow wildflower seeds is March or April or in September. The site you choose should ideally be in full sun and well-drained, though there are mixes for other areas such as shady or damp sites where the species chosen will thrive in such conditions.
Plug plants. Using plug plants to create a meadow is more labour intensive and expensive but ultimately often more effective at establishing perennial meadow plants. Approximate cost: a tray of 104 plugs of 13 different species is about £90 and would cover an area of approximately 20 square metres. Method: create a grid of metre squares with canes and garden string and plant about 5 plugs per square metre.
Meadow turf is sold by the metre and has been created by the suppliers sowing onto a mesh or a biodegradable plant fibre backing. The latter is the preferable method. Like seed mixes, in the case of both plug plants and meadow turf, there are numerous permutations depending on aspect, site conditions etc. The method of site preparation is the same. You’ve probably all seen the wildflower meadow around the base of The Hive in Kew Gardens? This was made using metres and metres of wildflower turf, much of which had to be pinned to the steep sides cut into the mound on which the structure is built.
It is always recommended, in particular where a meadow is being created in a formerly lawned area, to sow yellow rattle seed in late summer to suppress the growth of the grass which if left unchecked will out-compete the floral element of the meadow. Yellow rattle, Rhinanthus, is a semi-parasitic plant which reduces the vigour of established grass.
Teasels. Dipsacus fullonum, grow to about 2 metres and as well as looking pretty in flower with fluffy mauve flowers to attract pollinators, dry back to spectacular seed heads which will attract charms of goldfinches during the winter months. Like foxgloves, teasels are biennials and complete their life cycles in two years: growing a crown of leaves in year 1 and flowering and setting seed in year 2. To establish an annually recurring display, plant the crowns two years running.
Berries & hips for birds I’ve concentrated on pollinators but as the season progresses and berries and hips develop, many shrubs are good food sources for birds. Examples include the shiny berries of the so-called Guelder rose, Viburnum opulus, a favourite for thrushes and redwings, or the pink and orange fruits of the spindle tree Euonymus europeaeus beloved of starlings. Another good reason for planting this useful shrub is that it is host plant of the species of aphid that in their turn attract an army of predators such as ladybird larvae which will deter aphids from infesting your roses and broad beans. Rosehips are a great food source in late autumn and winter for birds.
WATER
Ponds. On a bat walk in August at the field, led by one of the rangers from Barnes Common, he described a pond as a ‘food funnel’ for species such as bats because it draws insects towards it on which bats can predate. In the same way that a watering hole in East Africa attracts animals from many miles around to quench their thirst, so a pond in your garden will act as a gathering point for an army of invertebrates. Not only the obvious waterside dwelling insects like dragon and damselflies, which if the pond is large enough to support a population of underwater creatures on which dragonfly larvae can feed, might breed there, but also pollinators like bees, hoverflies, moths and butterflies will swoop down to the surface of a pond to drink. As I mentioned before, a garden pond will provide a wonderful habitat for amphibians like frogs, newts and toads. It doesn’t have to be enormous, but you must provide some form of exit route for these creatures to get out of the pond because they spend much of their time on land, sheltered in the undergrowth. A staircase arrangement of bricks leading to the surface or a wooden ramp as I’ve seen in some gardens will enable them to get out when they need to. The huge advantage of having a resident colony of amphibians is that they will suppress the population of snails and slugs. An example of the phenomenon that introducing wildlife friendly gardening practices, like making a pond, will have a beneficial effect on the way you garden. If you’re making a pond from scratch, be sure to site it in a position where it will get direct sun for at least 8 hours a day in summer. The best practice is that one half or up to two thirds of the pond should be covered with vegetation. Having a small fountain in your pond will not deter the wildlife and will help to oxygenate the water. Even in a dedicated wildlife pond, as opposed to one that is ornamental, it is important to make sure that the water is kept moving, to avoid the water becoming stagnant. It is best not to install a water feature which throws the water high into the air as this will cause the water to evaporate more quickly in hot weather and in a dedicated wildlife pond would look incongruous. Just install a water pump with the fountain base just showing above the water line for a gentle bubble effect which is enough to agitate the water. Even with a fountain, you should still introduce submerged oxygenating plants (available from water garden suppliers) as these provide a habitat for small animals to live and breed.
Cleaning ponds. Even taking these precautions, ponds inevitably get clogged up and benefit from skimming over occasionally with a fishing net to remove blanket weed and any fallen leaves from neighbouring trees. Don’t immediately empty the debris you collect into the compost bin: just deposit it on the side of the pond to give any creatures that you’ve scooped up to disperse back into the pond. After about three days you can pick up the waste and dispose of it.

There are dozens of aquatic plants available for garden ponds, with waterlilies being the most popular. Whatever you choose be sure to avoid invasive species like parrot’s feather (Myriophyllum aquaticum), though the sale of this is restricted and shouldn’t even be available from a reputable aquatic plant retailer. Choose your plants according to the scale of your pond: there are several dwarf cultivars of water lily available for smaller ponds. Make sure to include some marginal plants around the edges of the pond for amphibians and insects like dragon and damselflies to shelter in. There are several rushes which look attractive though bear in mind they can grow quite densely and are hard to shift once established: an example would be Juncus effusus (Soft rush). If you’re looking for an online supplier, Lincolnshire Pond Plants is a good one. They won gold at both Chelsea and Hampton Court Flower Shows and are really helpful with advice as to the best plants to choose.
Bird bath If you hang birdfeeders in the garden for garden birds you should also provide a bird bath or similar to enable them to drink and bathe. Do keep it as clean as possible and make sure it’s kept topped up.
Bee bath. You don’t have to have a full-sized pond to help pollinators to swoop down and drink: you can provide a shallow saucer with a few pebbles which you keep topped up with water.
Having covered the basic 3 elements needed to attract wildlife to the garden, I’ve a list of DON’TS to share with you.
DON’T use weedkillers. In the words of Joni Mitchell in Big Yellow Taxi ‘Hey farmer, farmer put away that DDT now, give me spots on my apples, but leave me the birds and bees, please’. She went on to sing ‘they paved paradise, put up a parking lot’, but run off from hard-standing which causes surface flooding is a whole other talk about resilient gardens! There’s no substitute for hand weeding accompanied by a good podcast or audiobook, not to mention a hori hori or Japanese trowel which while it might look like an offensive weapon is the most useful tool in my gardening toolbag.
DON’T use pesticides. Once you establish a good balance in your garden by attracting natural predators with shelter, food and water, you won’t be as troubled by aphids, slugs, snails and pesticides won’t be needed. There are biological controls available for certain pests in the form of predators or pathogenic nematodes but this is a whole other topic and perhaps a talk designed to encourage wildlife is not the forum to be looking at ways to kill certain elements of it!
DON’T use slug pellets aka molluscicides. Although the really toxic ingredient in slug pellets (metaldehyde) is now banned, you might have some of the old product in the shed. It’s poisonous to birds and pets as well as gastropods and SHOULD NOT BE USED.
DON”T let the cat out at night. According to a Landscape & Urban Planning report in April 2022 on small mammal predation, UK cats kill 160-270 million animals a year, a quarter of them birds. Cats Protection League recommends the following steps to reduce predation: a dusk to dawn curfew, feed cats meat-derived protein food, and playing with your cat for at least ten minutes a day.
DON”T over-illuminate your garden. It’s better to use a few solar-powered bulbs than an elaborate lighting system that confuses birds who don’t know what time of day it is and a brightly lit garden deters bats.
DON”T deadhead roses from late summer onwards. Leave the spent flowers to develop into nutritious hips for over-wintering birds. They look decorative too.
DON’T cut hedges or large shrubs before checking for nesting birds.
DON’T cut sunflower heads when the flowers have finished. Leave them in place after they have finished flowering as blackbirds love the oil rich seeds.
Here are a few suggestions for wildlife friendly gardens which are open to the public:
Kew Gardens: especially the natural area in the south of the Gardens.

Long Barn: Vita and Harold’s gardenbefore Sissinghurst
Most people, when they move to a new property, make some changes, perhaps a new kitchen or bathroom, or even an extension. When in 1913 Vita Sackville-West and Harold Nicolson, home from a diplomatic posting in Constantinople, bought two farm labourers’ cottages and adjoining land in the village of Sevenoaks Weald in Kent, they went a step further and moved a mediaeval barn from the bottom of the hill joining it to the cottages to create a large house. Their radical approach to property renovation extended to garden-making, culminating years later in the creation of the unique gardens at Sissinghurst.
I visited Long Barn on a blistering hot day in early June. Organised by the WGFA, the visit consisted of an introduction to the property by the owner Rebecca Lemonius, followed by a tutorial in plant sketching by head gardener Anna Ribo. It was a very memorable and rewarding day in a fascinating garden. The link with one of the twentieth century’s most celebrated gardeners and garden writers made it all the more special. As for the art element, Anna’s non-judgmental approach gave this non-artist the space and freedom to have a go at drawing the bold planting combinations without feeling daunted.
Having grown up only 1.5 miles away, in her ancestral home Knole (nicknamed ‘the calendar house’ because of its reputed 365 rooms), it was important for Vita to live somewhere with an intriguing history. Long Barn was reputed to have been occupied at one time by the founder of the printing press, William Caxton. The house went on to develop more history when in the 1930s, after Vita and Harold had decamped to Sissinghurst, it was let to aviator Charles Lindbergh and his wife when they sought solitude and privacy from the press intrusion following the kidnapping of their infant son in 1932. During the 2WW the house was used as a nursery by the NSPCC to accommodate children affected by air raids. Rebecca told a touching story of her correspondence with a gentleman who had lived at Long Barn during this period. Following his recent death, his ashes are to be scattered in the garden.
In developing a new garden at Long Barn, Vita and Harold addressed the property’s sloping site by installing a terrace. Architect Edwin Lutyens, a lover of Vita’s mother Victoria, the spirited Baroness Sackville, advised on the construction of a series of raised beds at the foot of the garden (now the Dutch Garden) and the planting of a long row of clipped yew columns across the middle of the main lawn, but is not known to have been involved elsewhere in either the remodelling of the house or development of the garden.

Vita and Harold made a good team when it came to making gardens. His strength was in the vision to create the structure and hard landscaping, whilst Vita’s talent was in choosing the planting, informed by her admiration for the writings of William Robinson, pioneer of the wild gardening style, a reaction to the rigidly formal bedding fashion of the Victoria era. The garden was said to be the glue which held their marriage together. When it was rumoured that a chicken farm was to be built on adjoining land, the Nicolsons looked for another property, a blank canvas on which to create a garden. And so they arrived at Sissinghurst which has of course come to be known as one of the great gardens of the world. They moved there in 1932 but didn’t sell Long Barn until 1945.
In terms of gardening partnerships, it’s clear that Rebecca and her head gardener Anna share a similar vision for the atmosphere they want the garden to evoke, their philosophy being that the design is led by their choice of plants. Anna explained that her approach to gardening at Long Barn (she has been there five years) is to be sympathetic to what is already there. A gardener has to approach a garden with a degree of humility, get a feel for the soil and condtions and get to know the client. The soil here is Weald Clay which is rock hard in summer and sticky and claggy in winter: they improve it as far as possible by mulching it with organic matter such as composted bark and spent mushroom compost which help to break up the clay. The only place they use grit is in the Cretean Bed, a narrow south-facing border running parallel to the Box Parterre where the plants are reminiscent of the Mediterranean style planting at Delos at Sissinghurst, with a limited colour palette accented by handsome multi-headed Aeoniums.
The Box Parterre
This large site consisting of several different areas or ‘rooms’ is maintained by what amounts to seven man days a week, and Rebecca and Anna recognise that ‘everywhere doesn’t have to be perfect all the time’. After an area has gone over, it is allowed to be quiet. With such a small team, there has to be a realistic view of what can be achieved in terms of maintenance. There is an irrigation system in place in the Dutch Garden, but everywhere else is watered by hand. A further challenge is posed by the rest of the village’s surface water draining down towards Long Barn. On the site of an old tennis court, they are developing the ‘Rose Meadow’ where roses are encouraged to be as tall as possible, interplanted with grasses and wild flowers such as cow parsley and buttercups.
Head gardener Anna is also a garden designer with a fine art background, and prefers to hand draw her designs rather than using a computer programme. When sketching a plant she told us you should look at the character of the plant and ask yourself is it, for example, upright, frothy, strong, structural? If you spent ten minutes a day on sketching the plants in your garden you would soon see progress. After these words of encouragement we were free to draw plants in the Dutch Garden which was a joyful experience. We hunkered down in the shade on the cool grass between the raised beds and drew the plants at close range, considering how one plant relates to its neighbours and trying to capture something of the sheer exuberance of the planting here. Since the day at Long Barn I have sketched in my garden for a few minutes but haven’t devoted enough time to it to see such progress. I certainly find it a mindful experience regardless of the results my concentration produces.
Anna shared some useful design tips for planning planting schemes. When assembling a choice of plants for a border you should introduce lots of different flower shapes. Umbels, the flattish umbrella-like flowerheads of plants such as Valerian officinalis, will attract beneficial insects like hoverflies which eat aphids. Heavily edit self-seeders when they have finished flowering, but don’t remove them altogether. For example bright cerise Gladiolus byzantina, itself a self-seeder, was lighting up the beds in the lower part of the garden with vibrant spires of flowers. In a large herbaceous border like those in the Dutch Garden, maintain planting pockets which carry a quiet period, during which you can introduce annual plants such as Ammi majus (more umbels!) Anna’s plant descriptions were wonderfully lively: she pointed out zesty euphorias and described small flowered, low growing plants as ditsy.
There was something of Great Dixter about the garden at Long Barn. I think it’s the handsome and weathered old house rearing up amidst a sea of bold colours and diverse flower shapes and leaf textures. The team at Long Barn have certainly honoured Vita and Harold’s horticultural legacy by maintaining the unique structure of a historic garden but within that framework experimenting and playing with scale and colour.
Here are some more of my images of the three acre site.
After a few non-gardening days last week with family coming to stay, I returned to volunteer at Osterley, to find that an interloper had arrived in the vegetable bed in the Tudor Walled Garden that we had thoroughly weeded a week earlier. Numerous substantial seedlings of gallant soldier had pioneered their way along the aubergine and chilli pepper rows. Gallant soldier is a corruption of this plant’s scientific name Galinsoga parviflora, a member of the daisy family which bears very small white flowers amidst serrated oval leaves.
I’ve got a new plant identifier app on my phone, Flora incognita, which swiftly identified the vigorous invader. Subsequent reading reveals other common names for this fast reproducing plant: quickweed, potato weed and (my favourite) galloping soldier. It was originally collected in its native Peru in 1796 and brought to Kew Gardens, from whence it escaped, earning the moniker the Kew weed! There’s a delicious description in William Edmondes’ ‘Weeds Weeding (& Darwin): The Gardener’s Guide‘, my weed bible, of the prolific Galinsoga parviflora being brought to Kew Gardens and ‘almost immediately galloping away down the street and all over London’. This conjures a vision of it heading north along Kew Road and marching across Kew Bridge to Brentford, with a breakaway battalion hopping onto the District Line to spread across the city.
We made short shrift of the energetic soldiers after some careful weeding around the precious crops. However, I’m expecting to see them back on duty this Friday after several days of heavy showers and relatively mild temperatures.
Every day’s a school day, as they say, and my education continued last Friday with an excellent butterfly talk and walk at Pensford Field, led by Ruth from Kew Gardens, who oversees the wildlife in Kew’s Natural Area (formerly the Conservation area). She began by listing the several benefits of butterflies: as pollinators, by spreading pollen from plant to plant while drinking nectar; as part of the food chain in the form of caterpillars which feed wild birds and even wasps; as an indicator species to signal the health of an environment as well as inspiring people to take an interest in the natural world. There’s a huge amount to learn about these fascinating creatures. For example that butterflies detect smell through their antennae which means that in polluted areas their numbers can be reduced because it’s harder for them to detect sources of food. It’s a blessing that places like Pensford Field and the surrounding gardens exist to support butterfly and moth populations, given the proximity of the Field to the South Circular Road.
Other key facts that Ruth shared with us: purple flowers attract butterflies; grow nasturtiums near brassicas as a sacrificial plant to prevent large and small white butterflies from feeding on the crop; stinging nettles are a vital food source for tortoiseshell caterpillars; always site a wilder area of the garden in a sunny spot; treat brambles as a beneficial plant because they provide shelter when other habitats are not available, perhaps during droughts; when you see two butterflies ‘dancing’ in the air, they might be mating or two males fighting! Species with darker wings such as the ringlet which has charcoal coloured wings are more tolerant of shade and can be found in woodland.
Ruth’s talk coincided with the Big Butterfly Count which runs until this Sunday 6 August. I sat in the sun in my garden at the weekend and spied a day flying moth (the Jersey tiger), a holly blue and what I think was a large white.
Although I did no gardening whilst my niece and three great nephews stayed last week, we did spend time in the garden when the weather improved mid week and I introduced the two older boys (aged 7 and 9) to ‘sun printing’. Earlier this year I attended a day course on cyanotype printing at London’s City Lit in March which I reported upon in a blog post. We collected some fallen leaves during a visit to Kew Gardens earlier in their visit and I had been collecting and drying some flowers and fern fronds for a few months in anticipation of their visit. The boys enjoyed the whole process starts with treating the paper with the light sensitive chemicals, drying it the paper with the hairdrier then carefully placing their finds onto the paper. They got really excited when they saw the change in colour of the background of the images once they were exposed to the sun. We dried the washed images on the clothes line and all agreed they weren’t bad for beginners!
Since visiting Chatsworth almost five weeks ago I have discovered the Channel 4 documentary Chatsworth House: A Great British Year. I’m glad not to have come across it before as it’s fun to see the house and garden again and learn how such a vast enterprise works. The kitchen garden featured in one of the shows and like everything at Chatsworth it is beautifully designed and cultivated. Even at the end of November when most of the crops had been harvested, there was plenty to see and interesting details to examine.
The kitchen garden occupies a sloping west-facing site of about three acres. A relatively new addition to the gardens, it was created in the early 1990s. As in the wider garden, water has been channelled from parkland behind the garden to feed rills and ponds. I was interested to see tulips being planted in handsome terracotta pots, tucked into a nook beside the cold frames. The lower boundary of the garden is formed by a tightly clipped beech hedge. Large golden stalks adorn a trio of metal frames fashioned into apples and a pear, each housing a yew shrub which in the years to come will fill out the frames to form topiary fruits at the entrance of the garden. Rhubarb forcers from Whichford Pottery in Warwickshire stand to attention like terracotta warriors. A couple of stone plaques caught my eye: a quirky mission statement for creativity from dress designer Paul Smith and a heart-shaped memorial to the late Duchess Deborah. Straight rows of chard and brassicas appear to radiate from the corner of the large plots in which they are planted.
Unmistakeable for their charred finish, David Nash’s sculptures look entirely at home in the Arboretum which occupies the upper slopes of the gardens. The gardens are separated from the surrounding parkland by a ha-ha, the eighteenth century innovation which enables a garden to blend seamlessly with the landscape beyond. Here the ha-ha is a stone retaining wall. I noticed that a meshwork fence has also been fitted near the top of the wall, presumably to deter deer from entering the garden and munching the rare specimen trees. On the subject of dry stone walling, an installation called ‘Emergence’ demonstrates the evolution of this ancient craft, fundamental to the rural landscape of not only Derbyshire but so many other areas of the country. It contains one giant rock, a reference to the practice of using naturally occurring boulders in field walls. The transition from the older random style of limestone dry stone walling to the more modern sandstone wall of shaped stones is marked by a giant pane of glass. The interpretation panel informed me that the glass also represents Joseph Paxton’s pioneering work on the Great Stove at Chatsworth which led to him designing the Crystal Palace for the Great Exhibition in 1851. Giant redwoods tower above the other conifers in the Pinetum, an echo for me of the area of Kew Gardens devoted to these majestic trees.
More nineteenth century technology features in much of the seating around the gardens at Chatsworth. Cast iron benches with a plant inspired designs are placed around the remains of the Great Stove and in the terrace beside the 3rd Duke’s greenhouse. I found nasturtiums, passionflowers and lilies of the valley, as well as a design showing gardeners sowing, raking, harvesting and scything.
The Serpentine Hedge separates the Maze from the woodland area beside the Canal Pond. A double row of symmetrically planted beech which curves in and out, this dates from 1953 and was inspired by the ‘crinkle-crankle’ walls found in many old gardens, the alternating concave and convex planes providing stability. Seeing the north face of the house reflected in the Canal Pond, the Emperor Fountain rising skywards in the centre, has to be one of my highlights of 2021. This end of the garden also contains more remarkable sculpture: a horse’s head by Nic Fiddian-Green
and Allen Jones’s Dejeuner sur L’Herbe, a 3D take on Edouard Manet’s famous painting. If asked to name a favourite work from the garden, I would choose Cornwall Slate Line by land artist Richard Long, which runs parallel with the Canal Pond. Not far away Dame Elisabeth Frink’s Walking Madonna strides through a grove of trees.
The north front reflected in the Canal Pond
The family’s dogs appear in several sculptures nearer the house, faithful hounds keeping watch or assembling on the steps leading to the north front with its Ionic capitalised pilasters and windows framed in gold leaf. A frieze above the windows features coiled serpents, part of the Cavendish family crest. This motif is picked out in a pebble mosaic on the terrace near the 3rd Duke’s greenhouse, reminding me of the two dachshunds, Canna and Dahlia, immortalised in similar fashion in the Walled Garden at Great Dixter.
Classical statuary also abounds in the gardens, reminding me that this place has been a treasure house of art for many centuries. More mundane perhaps, but elegant in its own way, is the weather station on the Salisbury Lawns near the Broad Walk where temperature, rainfall and hours of sunshine are recorded and reported to the Met Office.

I shall leave you here with a final image from my memorable visit to Chatsworth, Flora’s Temple decorated for Christmas.
Well, not quite the last image. The finger post pointing the way to Chatsworth marked my exit in the early evening dark from the park into the village of Baslow where I was staying. It’s also inviting me back one spring or summer to explore further and to see Dan Pearson’s Trout Stream planting and Tom Stuart-Smith’s Arcadia in their full glory.
The designers of the show gardens in this year’s festival successfully conveyed the message that we gardeners cannot ignore the fact that our climate is becoming dryer and hotter. We need to put sustainability into practice by making our outside spaces resilient to such changes. Alongside this, and often as a consequence of gardening in this manner, we can attract and sustain the wildlife which would otherwise fall prey to climate change, pollution, the indiscriminate use of pesticides and the mania for covering our domestic open spaces with artificial grass or impermeable hard landscaping.
Tom Massey’s RHS Resilient Garden contained clever solutions to some of these threats. In the sunny front garden area, freshly dug gravel was replaced with recycled aggregate made from construction waste. ‘Rubblazzo’ paving made with such waste also featured. Rather than excess water produced by heavy rain storms overwhelming the sewage system, run-off was reduced by gathering the water into a wide shallow pool spanned by a boardwalk constructed from reclaimed timer. Day lilies, Agapanthus and (I think) Origanum vulgare contributed to a predominantly yellow, blue and mauve colour palette. To coincide with the unveiling of this inspirational garden, Tom Massey has penned a book for the RHS, Resilient Garden: Sustainable Gardening for a Changing Climate.
Unlike the Chelsea Flower Show where only invited guests get to step onto the show gardens, many of the Hampton Court gardens encouraged you to walk through them, a far more immersive experience than standing behind a rope and craning your neck to see the furthermost corners of the exhibit. The path in the RHS Wildlife Garden designed by Jo Thompson and Kate Bradbury replicated an old railway track with disused industrial land on one side (suggested by rusting machinery) and the rear portions of urban gardens on the other. If proof were needed that the clever planting in this garden was specifically designed to attract pollinators, the flowers of purple orchids and bergamot (Monarda didyma) were being mobbed by small skipper butterflies. The planting scheme included the native hawthorn, Crataegus monogyna, often cited as one of the best species for providing a food source for wildlife: nectar rich flowers in spring for invertebrates and juicy berries in the autumn for birds.
The winding path in Carol Klein’s RHS Iconic Horticultural Hero Garden passed six habitats: a bog garden representing wetlands, a small wood planted with beech trees, a native species rich hedgerow, a meadow blending grass and perennials, a rocky mountainside area for alpine species which merged into a shingly beach. The variety of species and cultivars used throughout was hugely impressive, as you’d expect from an expert plantswoman like Carol Klein, exemplified by these purple, mauve and silver shades in differing flower forms creating an exquisite painterly effect. There was even a vegetable patch and a greenhouse in which Carol could be seen sharing propagation technique tips with visitors. The plants used in the gravelly seaside garden were raised for the show by Beth Chatto’s Plants and Gardens. I loved the blend of mauves and deep pinks of Verbena officinalis var. grandiflora ‘Bampton’ and Allium sphaerocephalon punctuated occasionally with pops of yellow and flowing Stipa tenuissima.
A restful pool sat at the heart of the Cancer Research UK Legacy Garden designed by Paul Hervey-Brookes. Looking at the photographs now, it is hard to imagine that a month earlier this tranquil space would have been a construction site. The willows and hostas sprouting between the massive rocks edging the pool gave the garden an air of permanence and screened visitors onto the garden from the show hubbub a few metres away.
I enjoyed the theatricality of the Oregon Garden, where a mini vineyard sat alongside a colourful meadow bordering a miniature lake. White corncockle (Agrostemma githago) shone out alongside pink and yellow Achillea, the overall palette deepened by burgundy Hylotelephium (formerly Sedum).
The key components for attracting and protecting wildlife (food, water and shelter) could be seen in a couple of the smaller show gardens. In the Nurturing Nature in the City garden by Viriditas, the walls created from stone-filled gabions would provide ideal homes for solitary bumble-bees as well as cover for small mammals. Ponds in rectangular boxes made from scaffolding boards made habitats for amphibians and invertebrates and drought tolerant and nectar rich flowers such as Achillea and Salvia nemorosa Caradonna were attractive for bees and butterflies. I liked the free-standing vertical garden idea where climbers like honeysuckle (a favourite for night-flying insects like moths) were being encouraged to grow up railway sleepers and along strainer wire fitted between the sleepers.
More wildlife friendly and sustainable ideas were included in The Wildlife Trusts: Renters’ Retreat designed by Zoe Claymore. This was full of clever solutions for making a garden which might have to be packed up and moved to a new space: a mini-pond in a pot; steel raised beds that can be dismantled and moved elsewhere, a tree planted in a container. The densely planted ferns and Lady’s mantle (Alchemilla mollis) supplied cover for insects and small mammals whilst bees and hoverflies would be drawn to the nectar in the foxgloves (Digitalispurpurea).
Hedges make wonderful habitats for wildlife. The Traditional Townhouse Garden designed by Lucy Taylor Garden Design was surrounded by copper beech hedging, with the burgundy colour scheme repeated in the bark of Tibetan cherry trees planted into huge pale green containers, underplanted with Lady’s mantle. Oversized chairs of green metal picked up the colour of the containers. A shallow circular pond accessible for amphibians was set within a sedum filled square. A ‘black’ and white planting scheme framed a large bronze apple: the bright white of Gaura lindheimeri ‘Snowbird’ contrasting with the dark petals of Viola cornuta ‘Molly Sanderson’ and Cosmos atrosanguineus.
I believe I am right in saying that ever since the first RHS Hampton Court 30 years ago, rose growers have exhibited in their own marquee, rather than the enormously long Floral Marquee. This makes for a wonderfully concentrated experience of exquisite flowers and fragrance.

There are another two ways in which Hampton Court contrasts with Chelsea: dogs on leads are permitted and you can buy plants at the show as well as all manner of horticultural accoutrements. Many visitors arrive armed with plastic crate trolleys to accommodate their purchases. I bought a beautiful purple flowered Streptocarpus from Dibbeys of North Wales for a friend’s birthday. It was lovely to chat with Lincolnshire Pond plants who were awarded a gold medal for their display (as they had been in May at Chelsea). In an effort to minimise blanket weed in my pond, I bought oxygenator water shamrock (Marsilea quadrifolia) which I was interested to learn is an underwater fern. I also stocked up on allium bulbs to plant in the autumn from WS Warmenhoven: more Purple Sensation to bulk up those already in the garden. Their display of numerous cultivars arranged against a black background was stunning. Having reviewed my photos, I’m now wishing I had also bought Allium sphaerocephalon which also popped up in several of the show gardens.
This brief account of the day inevitably cannot do justice to a fantastic show which I so enjoyed returning to after an absence of several years. I’ll leave you with a few more images from the day.
In some gardens a sundial helps you to tell the time. At Luton Hoo Walled Garden the walls themselves ARE the timepiece. The octagonal walls enclosing this 4.83 acre space were aligned to capture the maximum amount of sunlight to aid the production of peaches and other tender fruits.
…some walls face the direction of sunrise and sunset at the spring and autumn equinoxes and at the midsummer and midwinter solstices, maximising the sunlight on the walls
Short History of the Luton Hoo Estate 2022
The Walled Garden was commissioned by John Stuart, 3rd Earl of Bute shortly after he bought the 300 acre Luton Hoo estate on the Hertfordshire/Bedfordshire border in 1763. Having engaged Robert Adam, the eminent architect of the time, to redesign the older mansion, he selected landscape architect Lancelot ‘Capability’ Brown, to reshape the park land surrounding it in the fashionable English landscape style with which Brown had made his name. As part of his vision for the estate, Capability Brown chose a 10 acre site on the highest part of the land, sheltered on two sides by woodland, on which to build a garden to supply the big house with vegetables and fruit as well as raising flowers with which to decorate the mansion. Within the 10 acre site, a 4.83 acre octagonal enclosure was built surrounded by high brick walls.
In the following decade Bute built a conservatory within the octagon for the rare species of plants he had collected throughout his life, including during his time advising George III’s parents Frederick and Augusta, Prince and Princess of Wales, on the development of a botanic garden in Kew. He also had a catalogue compiled in 1777 of the plants grown on the estate which has been consulted when selecting some of the plants now grown in the Walled Garden. That conservatory was dismantled by Lord Bute’s eldest son, and when the estate was sold to Mr John Shaw Leigh in 1847 he built a new conservatory and boiler house. Leigh also revitalised the garden by installing a new drainage system and underground water storage tanks. The area outside the walls is known as the ‘slips’ where a fine double fronted house was built for the head gardener together with glasshouses. The garden became a showcase of horticultural excellence, producing thousands of bedding plants every year for the formally laid out beds and fruit trees trained into extravagant designs. A vinery housed several grape varieties and out of season carnations were grown in heated glasshouses as well as orchids.
The birth of the Edwardian era brought another change in ownership with Sir Julius and Lady Alice Wernher buying Luton Hoo in 1903. The old conservatory was demolished along with the north-west wall (the eighth wall of the octagon) and a huge range of glasshouses (229 feet long) was commissioned from Edinburgh firm, Mackenzie and Moncur, with a fernery at its centre topped by an elaborate glass cupola, and six smaller houses. More propagation houses were built by Foster and Pearson and 54 gardeners were employed under the leadsership of head gardener Arthur Metcalfe who worked at Luton Hoo until 1934. During the 2WW the Women’s Land Army trained in the Walled Garden. After the war, areas of the garden ceased to be cultivated, and the glasshouses became increasingly expensive to heat and maintain. Part of the garden was used to rear pheasants and a garden centre was established in the northern section of the garden, which operated until 1977, after which the Walled Garden remained unused as a productive area until the first decade of the millennium.
After a research project was instigated to investigate the viability of reviving the garden and opening it to the public, since 2006 the energy and enthusiasm of a loyal cohort of volunteers (now numbering approximately 120) has been harnessed to carry out building conservation work and make a garden which is both decorative and productive. A team of research volunteers continues to uncover the stories behind the garden and the people employed there over the centuries. Thanks to the volunteers, the Walled Garden is one again a cared-for space, accommodating numerous beds and borders producing fruit and vegetables and an array of herbaceous perennials, annuals and shrubs.
The ‘service’ areas beyond the walls, have been sympathetically restored as a unique record of life working in a grand garden at the turn of the C19 into the C20.
At this stage of the conservation project the Edwardian glasshouses remains unglazed, but the framework of the range remains intact and the houses have been made safe to explore. All possible original features have been preserved such as winding mechanisms, ironmongery for opening and closing air vents and decorative grille work on the flooring above the hot water pipes. Whilst it would be wonderful to see the glasshouses restored to their former glory, there is something eerily beautiful about the skeletal forms which dominate the northern side of the garden, facing out to the southern sky to harness as much sunlight as possible as they once did for the generations which have gone before.
I visited Luton Hoo Walled Garden on 7 June, coinciding with one of their Open Wednesdays and joined a guided tour of the garden. Here I learnt that the gardeners referred to early colour photographs of the garden, known as ‘autochromes’, when reinstating the layout of the garden. But whilst honouring the long history of a garden on this site, this garden is not being frozen in time as an example of Edwardian extravagance. The estate owners and volunteers are ensuring that this unique garden can be enjoyed by everyone now and into the future. They are working with SENSE college in Luton to involve young adults with complex disabilities in growing things as well as other outreach projects with the wider community.
The botanical legacy of John Stuart, 3rd Earl of Bute, is evidenced in the names of several plants. Sadly, like my own handsome regal Pelargonium Lord Bute, those being propagated for sale in the garden’s produce shop suffered despite being protected from last winter’s freezing temperatures. But a week or so after my visit, during my Friday morning stint at Osterley Park and House, head gardener Andy Eddy led us over to the American Border to see the ‘silky camellia’ in flower: Stewartia malecodendron, named for the botanist and aristocrat (and erstwhile Prime Minister!) whose Luton Hoo Walled Garden is going from strength to strength.
