Hampton Court Palace Garden Festival 2023

5 July 2023

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 (Digitalis purpurea).

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.

These Walls Have Years

Luton Hoo Walled Garden

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.

Our Friend in the North: Tom Stuart-Smith at RHS Bridgewater and Trentham Gardens

Tom Stuart-Smith has put his mark as a landscape architect on numerous gardens across the country. I’ve seen his planting at Chatsworth House in Derbyshire and in July 2021 was fortunate to go to the inspiring garden at his home, Serge Hill at Abbots Langley in Hertfordshire. This last weekend gave me the opportunity to compare two more of his creations: the new Royal Horticultural Society garden, Bridgewater, south of Manchester and the Italian Garden at Trentham Gardens, Staffordshire.

Steady rain fell throughout the afternoon at RHS Bridgewater but it meant that the gardens were very quiet enabling us to see the structure of the garden for which Tom Stuart-Smith created the masterplan for the development of the site as a centre of excellence for horticulture in the north-west. He also designed the layout and planting of the Paradise Garden which forms one half of the restored 11 acre Weston Walled Garden, a major feature of the new garden, as well as the Worsley Welcome Garden located close to the Welcome Building.

The joy of a RHS garden (like RBG Kew and other botanical gardens) is that all plants are labelled, so you start learning as soon as you step outside into the garden. A perennial honesty (Lunaria rediviva) soon caught my eye. In borders between the outer and inner walls of the walled garden, massed plantings of tulips and daffodils lit up the gloom of the rainy afternoon. Terracotta rhubarb forcers nestle amongst the bulbs, a clue to the presence at Bridgewater of the National Collection of rhubarb, with 100 cultivars having recently been moved from RHS Wisley. I also liked the gnarly branches (driftwood?) which accent the border every so often, resembling abstract sculptures.

I love to see show gardens from flower shows re-purposed, and the high brick wall of the Weston Walled Garden provided a perfect backdrop for Windrush Garden from RHS Flower Show Tatton Park, 2021, designed by Dawn Evans.

The Weston Walled Garden is divided into two equal halves: the Paradise Garden and the Kitchen Garden. High metal obelisks, designed to resemble the chimney of the original boiler room which heated the glasshouses which served Worsley New Hall, punctuate the enormous Kitchen Garden which contains more than 100 planting beds! Unobtrusive strainer wires are fitted along the walls. to support an impressive collection of wall-trained fruit, including heritage pears.

The heart of the Paradise Garden is a very large body of water, the Lily Pond, fed by two rills which intersect the garden. Partially covered by a decorative grill in a geometric design, the rills are just one example of the wonderful attention to detail manifest throughout Bridgewater. At this time of year and on a wet afternoon, the colours were muted: greens and the reddish brown of the beech columns planted around the Lily Pond. From photographs in the guide book and having seen Serge Hill* in high summer, I can imagine just how colourful the Paradise Garden must be later in the season. One of the features of Serge Hill which impressed me was the Plant Library, trial beds laid out in a numbered grid, designed as an open resource for garden design students to see how plants behave and move, featuring many drought tolerant plants. I’m imagining that some of the species in the Plant Library are also planted into some of the Paradise Garden’s 80 planting beds.

Two new glasshouses in Victorian style have been built along the southern wall of the Paradise Garden, to house tender specimens such as Aeonium. On the opposite side of this wall stands the Old Frameyard, home to the boiler room and its chimney, as well as potting sheds (now an exhibition space), a brand new Propagation House, and beds laid out for plant trials. Near here we spotted another show garden, the Blue Peter Discover Soil Garden designed by Juliet Sargent for the Chelsea Flower Show in 2022.

Just beyond the walled garden stands the restored Garden Cottage, once home to the the head gardener of Worsley New Hall. The cottage is surrounded by an immaculately mowed, semi-circular lawn.

Heading into the wooded area of Bridgewater we found a friendly ent, and in the fields beyond the woodland, the Pig Pen for the black Berkshire pigs which have been used throughout the creation of Bridgewater to act as ‘biological ploughs’ and clear the ground in various parts of the garden before planting. Here and there in the woodland, are remnants of the original gardens and to the north of Ellesmere Lake, the remains of the terraces which stood in front of Worsley New Hall, the large Victorian House which was demolished after the Second World War.

Flowing from Ellesmere Lake down the hill to Moon Bridge Water, the new body of water next to the Welcome Building, is the Chinese Streamside Garden, which is intersected with a series of small pools and crossed by a series of wooden bridges. The planting is designed to reflect the numerous Chinese native plants which are now favourite shrubs and trees in the west: acers, magnolias, primulas included.

Thankfully the weather improved for the second garden visit of the weekend: Trentham Gardens near Stoke-On-Trent, Staffordshire. Here three eminent contemporary garden designers have made their mark on a garden which has its origins as an eighteenth century landscape garden (the lake around which the garden and parkland are located was designed by Capability Brown). Piet Oudolf designed the Floral Labyrinth which stands beside the River Trent at the eastern end of the garden, near the ruins of the Italianate Victorian house: 32 beds of herbaceous perennials in the Dutch designer’s trademark prairie style. The beds were just beginning to spring to life, with tantalising crowns of greenery promising a lush summer display. Snakeshead fritillaries (Fritillaria meleagris) nodded gracefully in several beds.

The Perennial Meadow Garden along the edges of the lake was designed by Professor Nigel Dunnett (Tower of London Superbloom, Gold Meadows London Olympic Park and the Barbican). The third of the designers to shape this garden in the 21st century is Tom Stuart-Smith. When she showed us around her own garden at Serge Hill in July 2021, his sister Kate Stuart-Smith told us her brother’s nickname in the family was GAT, Great Arbiter of Taste! The Italian Garden at Trentham is certainly a class act. Like Bridgewater’s Paradise Garden, it is on a grand scale, a formal parterre style layout of symmetrical beds, some edged with low hedges arranged around low walled formal pools, centred with fountains. The Italian theme is reinforced with classical statuary, monumental urns and slim columns of Irish yew standing in for cypresses. The simplicity of the planting prevents the space from seeming unduly elaborate. One set of beds is planted with white flowers and silver-leaved plants: tulips, narcissus and a white-flowered Brunnera with silver-veined leaves, possibly B. macrophylla Mr Morse.

Low evergreen domes and similarly scaled stands of grasses planted into lawned areas echo the yew domes dotted on the lawn alongside the Worsley Welcome Garden at Bridgewater.

The Italian Garden is divided from the Floral Labyrinth by an arched pergola running its entire length, entwined with climbing roses and Wisteria, yet to bloom. Running alongside the pergola is the David Austin Rose Border, designed by Michael Marriott. I can only imagine how fragrant and beautiful this must be when in flower. The roses were certainly looking wonderfully healthy last Saturday.

Whilst brief, my 36 hour trip to the north west was enormously satisfying, and it was a joy to see Tom Stuart-Smith’s work in both gardens.

Finding Frogmore

Little did I know on 1 September, as I walked with a friend along The Long Walk in Windsor Great Park, that a few weeks later Queen Elizabeth’s funeral cortege would cover the same ground en route to St George’s Chapel in Windsor Castle. Our destination was Frogmore House and garden, open for charity (in this case Guide Dogs) on one of its three or so fundraising occasions of the year.

Extending to 35 acres, the garden at Frogmore is less than a quarter of the size of Kew Gardens, the other estate influenced by the horticultural enthusiasm of Queen Charlotte, consort to George III. Apart from Frogmore House itself, another major landmark in the grounds is the Royal Mausoleum where Queen Victoria and Prince Albert are buried. The site of this Byzantine style edifice was identified by Victoria within days of her husband’s premature death in December 1861. The Royal Mausoleum has been described as one of the finest Victorian buildings in the country. The imposing building stands across the Frogmore Lake from a smaller mausoleum, built to accommodate the mortal remains of Victoria’s mother, the Duchess of Kent.

The Frogmore estate also features several smaller buildings and follies, all of which combine to create a fascinating landscape from both a historical and garden design point of view. An elegant iron bridge, reminiscent of a bridge across the lake in St James’s Park, crosses Frogmore Lake which twines across the centre of the garden, its sinuous outline emulating a river. Looking back from the promontory to which the bridge leads, there’s a fine prospect of the south western facade of the house. A short walk from the bridge and one can see the Duchess of Kent’s Mausoleum and, nestled at the lake’s edge, the ‘Swiss Seat’, a timber hut dating from around 1833 which the guide book describes as ‘faced with split trunks arranged as gothic blind tracery’.

One of my favourite buildings at Frogmore was Queen Victoria’s Tea House. Built of brick and tiles, it consists of two small rooms joined by a loggia. An enormous Wisteria is trained over the colonnade which surrounds the building. Elaborately decorated chimneys dominate the tiled roofs of each half of the building. There were a few small Wisteria blossoms to be seen, presumably the third flush. This has been a plant which has revelled in the summer’s heat this year it seems, judging by this and the specimen in my own garden. Evidence of the drought was apparent elsewhere at Frogmore, where the soil in the borders (mostly shrubberies) was dry and cracked.

Another Wisteria lent a suitably mysterious air to the Gothic Ruin, almost obscuring its beautifully arched windows. An onion dome tops an elegant white marble structure, the Indian Kiosk, presented to Queen Victoria in 1858. There are few flower beds in the Frogmore garden. The glory of the place is the variety of trees from across the world which, with the lake, create a peaceful parkland within the Great Park itself.

From River to Green

65-73 Kew Green, NGS openings 22 & 29 May 2022

Imagine a 300 foot long garden behind an elegant Georgian house, running down to the towpath along the southern bank of the River Thames. Now imagine five such gardens, each divided into a series of ‘rooms’, rambling roses and Clematis softening the boundaries between each garden.

These five gardens, 65 to 73 Kew Green, open for the National Gardens Scheme on two Sundays every May, raising funds for charities including Marie Curie and MacMillan Cancer Support. I enjoyed my first visit on the afternoon of 22 May so much that I returned with another friend on the evening of 29 May.

Entered via gates along the towpath, each garden boasts an impressive compost area and some have leaf mould piles as well. Next come the kitchen gardens, ranging from rectangular box-edged beds to a potager blending vegetables and ornamentals. Planting styles and colour schemes vary from one garden to the next.

One garden, the narrowest, adheres to a restrained palette of greens and whites, the borders punctuated with carefully trimmed box balls and yew pyramids. A soft cottagey style of planting predominates elsewhere, borders billowing with roses, peonies and irises. Euphorbias introduce a lime green accent here and there.

Each garden includes a woodland garden, exploiting the shade provided by the very mature trees planted along the towpath, the perfect environment for shade-loving plants like Solomon’s Seal (Polygonatum x hybridum). In one, variegated ground elder (Aegopodium podagraria ‘Variegatum’) lightened what might otherwise have been a gloomy spot.

There were some stylish garden pavilions and studios, one of them spanning the width of the garden, and a few well-placed sculptures.

Lawns are immaculate, but sizeable areas had been left unmowed in the spirit of ‘No Mow May’. The lawns tend to be closer to the houses, and surrounded by generous shrub borders. I was impressed by the variety of trees: including the maidenhair tree (Gingko biloba), contorted willow (Salix Tortuosa) and black locust (Robinia pseudoacacia). Pot gardens occupy some of the paved areas adjoining the houses.

73 Kew Green is I believe, the widest of the gardens, and features a small orchard, the trees set amidst a meadow through which inviting paths have been mown. In at least two of the gardens, sympathetic hard landscaping has been used to create ponds and water features, tranquil focal points in already peaceful spaces.

I succumbed to the temptation to buy a couple of plants at the plant sale set up at no 73, both relative rarities. Here are the descriptions provided by the donor of these plants:

  1. Malvastrum lateritium. In full sun and well drained soil this little mallow gives many flowers of a soft orange with a red eye. Its stems sometimes root as they creep about. Its perfume was once described by a friend as like a ‘high class talc’. From N. Argentina, S. Brazil.
  2. Lychnis ‘Hill Grounds’. A chance hybrid from Janet Cropley’s garden, Hill Grounds, Northants. Lychnis flos-jovis x L coronaria. A sterile hybrid, therefore grows plenty of bright pink flowers over a long period.

In my garden this afternoon I reduced two large clumps of Michaelmas daisies beside the trellis which supports climbing rose ‘Blush Noisette’ with a view to revamping that part of the flower bed and shall plant these new acquisitions, as well as Anthriscus sylvestris Ravenswing, which I bought last Wednesday morning at Hardy’s Plants after a marvellous tour of the nursery led by Rosie and Rob Hardy: the subject of my next blog.

Before finishing, I want to thank the owners of the Kew Green gardens for their generosity in opening their gardens for the NGS and their patience with visitors like me asking lots of questions.

Willowy supports

I wrote earlier this year about the many different ways in which to support garden plants and trees. On 4 May I learnt how to build supports for herbaceous perennials using willow at a workshop organised by WGFA (Working for Gardeners Association) at the privately owned Dunsborough Park in Ripley, Surrey. WGFA was founded in 1899 as the Women’s Farm and Garden Association and one of its principal objects is to ‘promote, encourage and establish the opportunities to study and practice within the horticultural profession’.

Now I do like a long drive, I don’t mean a three hour slog along a motorway but a gracious tree-lined approach to an elegant house and garden! And Dunsborough Park didn’t disappoint, said drive beginning with four tall brick built gatehouses, topped with domes which wouldn’t look out of place in an adaptation of Wolf Hall.

Redbrick gatehouses

The drive itself seemed about quarter of a mile long and so many rabbits hopped along in front of the car I began to feel I was in a Disney movie! Arriving at a locked gate with an entry phone beside it I realised I’d used the wrong entrance, but thankfully one of the two full-time gardeners at the property, Oleg, kindly opened the gate for me. Apparently access to the garden on occasions such as this is via another entrance behind the High Street in Ripley. I clearly missed that email! Since 1997 Dunsborough Park has been owned by garden statuary dealer Dolf Sweerts de Landas Wyborgh and his wife Caroline. Antique sculptures abound throughout the garden. Even in the work yard where the gardeners’ bothy is located, a ferocious lion stands guard.

But we were there to learn the craft of willow plant support making, (where flexible willow and hazel stems are woven into domed structures through which tall herbaceous perennials can grow, eventually concealing the woody ‘cage’ beneath), not to swoon over our surroundings. We were a group of eight gardeners, all working in horticulture, from across the south of England. Head Gardener James Gillions and Oleg led us to the walled Dutch Garden for a demonstration before we were let loose to have a go at building the structures ourselves. With four slim coppiced willow branches already in situ above a clump of Delphinium, Oleg skilfully bent the pliable wood into a series of arches, at approximately chest height, using garden twine where necessary to secure the structure. He then wove the smaller branches and twigs together to form a rounded dome to prop up the stems of the plant. The finishing touch to the structure is a cat’s cradle fashioned from garden twine, about halfway up the poles for support as the plant grows upwards.

Demonstration over we were set to work in a double herbaceous border intersected by a path leading to the Dutch Garden on one side and to the door of a large Victorian greenhouse on the other. Named the Penelope Hobhouse borders, they were originally created by the eminent garden designer, their distinctive feature being standard Wisterias planted at regular intervals along the borders. Apparently the borders were replanted in 2005 with a blue and white colour scheme. Our task was to build supports for the delphiniums and peonies in the border, still low mounds of greenery in early May. Having picked out four suitable canes from a generous pile of pollarded willows harvested on the estate in February, before the emergence of the leaves, we used a heavy metal pin and sledgehammer to make holes deep enough to accomodate the canes. Given the extraordinarily dry April we’d had this wasn’t as easy as you might think. the soil at Dunsborough is very sandy and free draining but its looseness meant that if the hole wasn’t deep enough, the poles tended to spring out of the soil when you started to bend the stem across to meet the neighbouring pole. The art is to find the natural bending point in the wood. Bend at too sharp an angle and the wood splinters.

We worked in pairs for the first structure, working individually after lunch. I thoroughly enjoyed the process of making the structures, using the natural curves of the material to guide the direction of the arches and ultimate contours of the support. By the end of the afternoon the elegant borders were inhabited by a dozen or so creatures which James observed resembled Doctor Who monsters. For a few weeks, these will be features in their own right until the plants they’ve been build to prop up grow up and through them, disguising the skeletal forms beneath. It was notable how different each ‘cage’ looked, some interconnected to make up an organic series of supports for a particularly large clump of delphiniums. When in the autumn the plants in the border die back, and are cut down, our wooden cages will be removed, shredded and composted.

I tore around the garden at lunchtime to capture the last hurrah of the tulips, a magnificent water garden with a folly-topped bridge, numerous statues and the garden’s resident golden retriever cooling off in the dipping pool. The following photos give a flavour of this fascinating garden.

Marching forwards

Meteorological spring starts on 1 March heralding a new season in gardens. Bulbs which have been nosing through the soil for several weeks without progressing much have suddenly burst into life and the garden is full of tight clumps of Tete a Tete daffodils. The days are stretching out too and the prospect of visiting other gardens is very inviting.

I started the garden visiting season by going to Hinton Ampner in Hampshire ten days ago. Run by the National Trust, this largely formal garden near Cheriton in Hampshire occupies a magnificent position overlooking the South Downs. From the terrace nearest the house (largely rebuilt after a devastating fire in 1960) the view extends south across downland studded with copses of trees, sheep grazing peacefully in the fields. Yew hedging separates the garden from the adjoining farmland. The four rectangular beds which make up the Sunken Garden are punctuated with plump yew pepperpots, the immaculate topiary lending this part of the garden its character. Much of this section of the garden is currently roped off, to prevent the grass being damaged in the winter months. But it is still possible to steal tantalising glimpses along vistas such as the Long Walk, where huge Irish yews stand like a guard of honour either side of a grassy avenue leading from a sundial to a marble statue of the goddess Diana.

The Sunken Garden

We walked beyond the garden across the fields in bright sunshine, the sensation of the wide sky and open space exhilarating for me, so used to working in smaller gardens where borrowed landscape means a neighbour’s tree and where the horizon (glimpsed from the footbridge over the District Line tracks) features a disused brewery in one direction and the Kew Pagoda in the other. Admittedly not a bad view but lacking in sheep.

More clipped yew, fashioned into billowing clouds several metres tall

The outside wall of the large Walled Garden is intriguingly buttressed with clipped box, the spaces between filled with dense swirls of winter jasmine.

To one side of the Walled Garden stand several lean-to glasshouses, one a vinery where the vines are planted outside, like the venerable Black Hamburg vine at Hampton Court. The whitewashed far wall of a neighbouring house supports a beautifully trained peach or apricot (I was peering through the glass and couldn’t see a label) which basked happily in the sunshine. This walled garden is full of variety: vegetable beds at one end and a lawn into which sinuous beds of daffodils have been cut. A deep shrub border lines a path to the side of the garden, featuring winter interest plants such as Cornus Midwinter Fire and Daphne bholua Jacqueline Postill: the tallest I’ve seen outside Wakehurst Place. The scent of the Daphne stopped me in my tracks.

The church of All Saints stands a short distance from the house, beside an orchard. I was intrigued by the tiled roof of the bell-tower which I read in the guidebook was added in 1879 when the tower was added to the C13 church. Spring flowers stud the East Lawn beyond the church, the daffodils superseding the snowdrops.

I mentioned the track-stopping scent emanating from a Daphne at Hinton Ampner. This reminds me that it’s easy to overlook how fragrant another winter flowering shrub can be. Yesterday I was at North Hill Nurseries near Chobham, buying plants for clients. The shade tunnel which houses shrubs such as Pittosporum and hardy Fuchsia is home to a large number of Skimmias . Their sweet perfume was intensified by the warmth of the spring sunshine and the confined surroundings. These are such good plants for small gardens: their domed form never seems to get too dominant and as evergreens they look good all year. My favourite (which I have in my garden) is Skimmia x confusa Kew Green: its creamy green flowers have been flowering for months.

When not at Hinton Ampner or spending other people’s money at the nursery, I’ve been working hard to make clients’ gardens (and my own, when I’ve time) ready for the warmer days. I’ve applied mulches to most of them: some shredded horse manure, some composted bark. I’ve pruned roses tall and small, trained climbers and a few ramblers, and weeded and pruned like fury, producing enough green waste to fill a recycling centre skip. Thankfully many clients have their own green bins but I do tend to make at least two visits to the tip a week, bulging bags crammed into the car.

At Osterley over the last few Fridays we’ve been edging the beds in the Tudor Walled Garden, ridding a border to the south of the house of green alkanet, and picking up the dead wood sprinkled across the lawns by Storm Eunice. Sadly the storm brought down a number of trees in the wider park and tore off a branch of the enormous Cedar of Lebanon on the Temple Lawn. We’ve also taken time out to admire the beautiful display of winter shrubs and spring bulbs in the Garden House. More winter fragrance here, with sweetly scented Sarcococca confusa overpowered by Narcissus Paperwhite Ziva.

To round up this summary of recent activities, I have two other items to report:

  1. I picked the first rhubarb of the season in a client’s garden last week. It is a large mature crown and must be a particularly early variety. I rushed home to check progress of my now three year old crown, growing in a container. The leaves are stretching out from the creased buds but it’ll be several weeks before I can pick a stalk or two.
  2. A large clump of frogspawn has appeared in my pond this week. Frogs occupy the pond every summer but this is the first time I’ve seen frogspawn. I can’t wait to see the tadpoles develop and hope there are enough ponds in the vicinity to house what promises to be a large brood.

Support Act

In January, if I’m not spreading manure on my clients’ gardens, I’m installing strainer wire supports for climbing plants on fences and walls. It’s one of those jobs that’s easier in winter, when the borders are clearer and the subject to be supported will, if it’s deciduous, have shed its leaves. I bought a new drill last year, which has made this job much quicker and means that I can drill into cement posts which I couldn’t with my old Black & Decker drill (inherited from my Dad). Once I’ve drilled the holes, tapped in the rawlplugs (if I’m working with brick or cement) and screwed in the vine-eyes I do battle with the coil of wire! When I first started putting these supports up three years ago I got into horrible tangles trying to unravel the wire from the coil without creating kinks in the wrong places. I’ve now learnt to pay out the wire gradually and avoid this problem. My favourite part of the procedure is after fastening the wire to the vine-eyes when I tighten it by turning the vine-eye through 360 degrees using a screwdriver. It’s so satisfying when the line is good and taut. Depending on the height of the wall or fence I’m working on, I put up 3 or 4 tiers of supports: enough to provide plenty of options when tying in the climber or wall shrub.

With a climbing or rambling rose, my modus operandi is to train the branches horizontally along the wires, tying them in as I go and only then pruning the branches back to an outward facing bud. Last week I worked with two very large climbing roses which had been attached to stylish horizontal timber fencing but in a vertical direction meaning that the flowers had accumulated at or near the top of the rose, 2.5 to 3 metres from the ground. It took several hours and a return visit to finish the task but now these two roses should I hope flower at eye level. Both were English climbers from David Austin, one Rosa Wollerton Old Hall and the other Rosa Mortimer Sackler: the first pale apricot, the other light pink. In the David Austin catalogue, Wollerton Old Hall is described as having a ‘strong, warm myrrh fragrance’ with ‘intense hints of citrus’: sounds gorgeous. Hopefully my efforts mean that this summer the perfume is pumped back into the garden rather than wafting skywards.

Installing these supports has made me consider the myriad of methods used to control the plants in our gardens by either holding them up from the ground or back against a wall or fence. Here I share a few examples from gardens I’ve visited and from volunteering in the gardens at Osterley House. In no particular order, here they are.

Wall supports

In early December last year we garden volunteers cleared ivy from the brick wall between the Long Border in the Tudor Walled Garden and the American Border. I noticed that a stretch of wall was studded with fixings for wire supports and Head Gardener Andy Eddy explained that the wall had once formed the backdrop of one of the Victorian glasshouses at the property which had been used to grow stoned fruits such as peaches and nectarines. The plants would have been trained against the wall onto wires arranged in closely spaced tiers. This was my first experience of using a tripod ladder and it felt so secure and steady in comparison with a stepladder, as well as being more manoeuvrable.

Hurdles

I saw these in use at both Great Dixter in East Sussex and at East Lambrook Manor Gardens in Somerset. These ‘Sussex hurdles’ measure H56 x W69 cm and resemble mini gates. They are used to support herbaceous perennials, preventing them from flopping onto and swamping other plants, or to prevent lawns and meadow areas from being walked on. In one of those moments of frugality I didn’t buy a hurdle from the nursery at Dixter, despite being tempted to do so and have put my name on a waiting list for one. They are made in the Great Barn there, from chestnut harvested on the estate.

Tree stakes

I usually install a single tree stake for small saplings, such as a Prunus Amonagowa I planted in a newly replanted local garden in November 2020. I wrap an adjustable black plastic tie around both tree and stake, ready to be let out once the trunk’s girth increases. I was very taken with this double staking method seen in the orchard beside the World Garden at RHS Hyde Hall in Essex. The tree looks sturdily supported and if the crop is anything to go by, the tree is very happy with the arrangement.

When I was in Kew Gardens today I was able to study the superstructure for the two huge stands of Wisteria growing in the northern end of the Gardens, between the Stone Pine and the Duke’s Garden. These are deliberately grown to eye level only, rather than on a taller support which means that you can see the flowers at close quarters in April, as well as appreciate their delicate fragrance. The plant’s sturdy branches are attached to cylindrical tree stakes measuring about a metre and a half, using buckled ‘belts’ which can be loosened or tightened as necessary.

Rose supports

Apart from the system I described above for training climbing and rambling roses against fences and walls, there are many different ways to support vigorous roses. I first saw the swag arrangement in Queen Mary’s Garden in The Regent’s Park, where tremendously thick ropes are swung from a wide circle of timber supports. It’s an absolute picture in June when it’s smothered in rambling roses. I saw a similar system, bare of flowers of course, in the Kitchen Garden at Chatsworth in November using a chunky chain rather than ropes. Another favourite of mine is the obelisk, which I’ve seen installed in varying heights in different gardens. Those punctuating the Broad Walk Borders at Kew Gardens are about three metres tall as are those I saw in the Rose Garden at Arundel Castle last April.

In my own garden I grow Rosa Blush Noisette against a wooden trellis and Rosa White Star around the timber support of a single arch. I attached strainer wire to each of the vertical planes of the post and each year I train the branches of the rose around the post in an anti-clockwise direction. Last year, in its third year, it reached the top of the post and I shall now encourage it along the archway.

At Osterley roses are grown against walls and on timber frames. Here is the rose trained onto the rear wall of the Garden House.

Metal supports formed into an arched tunnel were festooned in roses and clematis in Kate Stuart Smith’s garden at Serge Hill in Hertfordshire which I was lucky enough to visit last July. A metal archway is a relatively new feature at RHS Wisley, located near the old entrance into the garden.

In September dahlias are the main attraction in Sarah Raven’s garden at Perch Hill in East Sussex. It was an education to see the methods used to support the array of colours and forms of dahlia abounding in this garden which showcases many of the varieties in the inspirational catalogue. Although almost hidden by foliage I could just make out a timber framework constructed I believe from silver birch. In her book A Year Full of Flowers*, Sarah Raven devotes several pages in the April chapter to the structures used at Perch Hill, each constructed afresh every year. I also admired the cat’s cradle effect of string between coppiced branches in another part of the garden.

Talking of coppiced branches, I spotted this simple but very effective way to hold up lavender used along the driveway at North Hill Nurseries, the wonderful wholesale nursery near Chobham where I buy plants for my clients. A single pole is supported by shepherd’s crook style metal stakes at just the perfect height to prevent the shrub sprawling onto the grass.

In the last year or so I’ve discovered the merits of the half hoop metal support, the taller versions of which are very valuable for keeping exuberant perennials like Salvia Amistad in check. They are very versatile: for example, two can be arranged in a ring formation or a single hoop can be enough to separate one plant from another. They are not cheap though and I shall continue looking for the mythical versions a client told me were once stocked at an excellent price by Wilko!

My final images are a miscellany of sui generis solutions to unique scenarios. V-topped struts support a limb of an ancient lime tree at Great Dixter. A massive banana plant in the Temperate House at Kew is held upright by strong wire encased in rubber tubing attached to very substantial wooden posts. And perhaps the ultimate in plant supports, the brickwork buttress for the trunk of the Pagoda tree (Styphnolobium japonicum) in Kew Gardens, the horizontal branches of which rest on metal stands.

I’ve omitted many, many other forms of plant support in this quick overview and can see this is a subject I shall revisit, as I collect more examples from my travels.
