Hampton Court Palace Garden Festival: Part 2

Plant Heritage etc.

Spending an afternoon chatting to people about plants ranks amongst my favourite pastimes. So volunteering in Plant Heritage’s seed shop on the final day of the show was a great pleasure. I arrived a couple of hours ahead of my 1pm start time and took in those parts of the show I had admired a few days earlier, and a few more I’d missed the first time: see below.

In February I spent an enjoyable day at Stone Pine, Plant Heritage‘s office next to RHS Wisley in Surrey, where I joined a team sorting seed collected by members for sale at 2024 shows. One member of that team was June James who holds the National Collection of Clivia. Those exuberant orange or yellow flowered houseplants occupy a glasshouse in her Hampshire garden. I was thrilled to find that the indefatigable June was my fellow volunteer in the seed shop. In between customers she explained the finer points of Clivia propagation.

As it was the final day of the show, the packets of seeds were being offered in a special offer of five for a suggested donation of £10. It was fun recommending combinations of plants for the tricky sites which customers described. The range of seeds was impressive, from common or garden love-in-a-mist and pot marigolds to some very unusual Clematis cultivars.

The seed shop was one element of a very large stand occupying much of the far end of the show’s huge marquee, the official title of which was Floral Marquee and Plant Heritage, highlighting the importance of the charity’s work in conserving cultivated garden plants for future generations. Two of the National Collections represented in other sections of the Plant Heritage display area were mini Hostas and Rosa Persica. Another section of the display encouraged plant lovers to consider starting a National Plant Collection of one of the 15 environmentally friendly plant groups that are not currently part of a National Plant Collection. Before the show, when I read about the plants needing a home, I got very excited and imagined squeezing more Caryopteris shrubs into my garden alongside the one shrub I already have. Or devoting a corner to the different cultivars of Origanum. Of course good sense prevailed and I realised I haven’t the room for such a venture, but how special it would be to curate one of these living plant libraries.

Just before closing time exhibitors sell off plants in scenes reminiscent of the January sales. On our stand, I bought a dainty flowered Sanguisorba and was kindly given a hot water plant (Achimenes) and an unnamed Pelargonium with very attractive leaf markings. June also has also given me the fruits from two plants in her Clivia collection: a challenge now to propagate them successfully and look forward to flowers in about four years’ time!

I’ve not been involved in the de-rig of a plant show before and it was an eye-opener to see how quickly the show is dismantled as soon as the last customer leaves the show ground. We all donned hi-viz and packed up the trays of seeds and other elements of the stand: pots, books and jugs of cut flowers (examples of the plants whose seeds were on offer). On the neighbouring display I watched as the plants were extracted from the ‘borders’ in which they were ‘planted’, revealing the ‘Chelsea planting’ method, where plants in pots are temporarily plunged into compost for the week or so of the show.

I mentioned that I arrived early that day. Here are some highlights.

The Lion King Community Garden designed by Juliet Sargent was awarded a gold medal by the RHS. Its warm colour scheme echoed the rising sun backdrop featured in the spectacular opening number of the stage show. The dry hedge shown here beside the yellow seats, is both a useful barrier in a garden and a wildlife habitat.

Scallop shell symbols point towards a garden inspired by the Camino de Santiago, one route of which passes through the forests of Galicia in Northern Spain. The statue represents a pilgrim (presumably the showers in the guest house were occupied and she’s opted for a skinny dip en route?) Not pictured is the clever route around the garden lined on either side with sweet scented star jasmine, through which tantalising glimpses of the pool were visible.

The Oregon Garden was the first of two USA themed gardens. Also featuring a central pool, its planting was evocative of the state’s rugged landscape with pollinator-supporting plants chosen to illustrate its biodiversity.

The elegance of the Antebellum South was the atmosphere evoked in the pocket garden replicated in the first section of the Explore Charleston Garden, morphing via a mulch of crushed shell into a beach representing the wild wetlands surrounding the city which I learnt are called the Lowcountry.

Look out for a future blog post about Denman’s Garden in West Sussex which I visited in late April. A corner of the garden (with garden designer John Brookes captured in a pool of light at work at his desk) was replicated to promote the RHS partner gardens along with Furzey Gardens in the New Forest in Hampshire. I visited the latter garden many years ago with a dear friend who lives nearby. She often took her children there when they were small and they loved to play in the range of treehouses. The Minstead Trust maintains the garden and supports people with learning difficulties to lead independent lives.

With time slipping by until my volunteering session was due to start, I briefly took in the several borders created by graduates of the London College of Garden Design, to celebrate the diversity of the daisy family. Here were an evocation of the planting beside a Wiltshire chalk stream, a display of healing remedies, a wildlife friendly border and a border of seed-bearing species, specifically designed to attract birds.

Next time I’m back at Hampton Court, visiting the palace gardens after hours and discovering they hold three National Plant Collections!

Hampton Court Palace Garden Festival: Part 1

Resilient Gardens

Two of my particular horticultural interests were more than satisfied at this year’s RHS Hampton Court Palace Garden Festival: resilient gardening and plant diversity. I was lucky enough to visit the show twice: first as a punter on the second RHS members’ day and on the last day as a volunteer on the Plant Heritage stand. In this post I’m reporting on the gardens at the show which were planted with an eye to our changing climate.

Climate forward gardening, resilient gardening, sustainable gardening, gardening for climate change: all these expressions describe the same idea. Given the gradual changes in our climate: warmer wetter winters and dryer summers (well perhaps not so far this summer) and extreme weather events such as droughts or flooding, it is vitally urgent that we adapt our gardens to cope with such changes and design new gardens with this in mind. The eight gardens in the Resilient Pocket Planting category demonstrated this admirably. Knowing that your garden will be seen from 360 degrees must pose particular challenges to the designers, but each pocket worked from whatever angle you viewed it. Admittedly they were’t easy for an amateur to photograph, but then that wasn’t the point. Be it rainwater harvesting, biodiversity, food forests, using sustainable materials: the designers of these small spaces had it covered.

Moon shadow moth garden

I loved the concept behind The Moonshadow Moth Garden. When I give my gardening for wildlife talks, I emphasise the importance of attracting moths into the garden with plants with pale flowers and evening scent. Moths’ importance as pollinators can get overlooked by the arguably more charismatic creatures like butterflies and bumble bees. The creamy flowerheads of Achillea millefolium provided lots of flat landing stages and the hazy purple tangle of Verbena officinalis Bampton made a sheltered habitat.

Conservation charity Buglife sponsored The B-Lines Garden to promote a network of nectar rich corridors for bees and other pollinators. By increasing the abundance and diversity of flowering plants in gardens, we can extend this network across the UK. I was chuffed to see that many of the plants I’ve used in the resilient pocket planting I made in my little front garden earlier this year, featured in this and several of the other pockets. Specifically in this image, the purple-speared Salvia nemorosa Caradonna. Also used in the B-Lines garden is the spiky-leaved Berkheya purpurea with which I had less success when I attempted without success to grow it in the back garden last year but I’m going to have another go with it knowing it’s going to attract in pollinators.

The Ripple Effect Rain Garden

Perhaps the first thing that comes to mind when considering what constitutes a resilient garden is planting for drought tolerance, but given our increasingly wet winters, rain gardens which harvest rainwater and absorb stormwater are just as important. In The Ripple Effect Raingarden, stepping stones made a path across a central wet channel between low mounds planted with species that can withstand temporary waterlogging. Reading about this garden, I’ve learnt a new word ‘berm’, meaning a mound composed of soil and vegetation to slow and absorb stormwater. The designer of the garden, Sarah Cotterill, is based in Ballina, Co. Mayo and the limestone used for the stepping stones is typical of the rock formations found on the west coast of Ireland. In this image the pink flowers of are those of Rodgersia ‘Bronze Peacock’.

I enjoyed chatting to Becky Box the designer of the pocket based on The Edible Garden at Berkeley Castle in Gloucestershire, where the garden will be re-located to the walled kitchen garden. She explained how she divides her time between her garden design work and working in the castle gardens. I loved the willow structures which represent the castle’s chimneys: not shown to best effect in this image I’m afraid.

The designers of the resilient planting pockets were mentored by the doyen of resilient gardening, Tom Massey, whose gardens at last year’s Hampton Court Show and this year’s Chelsea Flower Show have done so much to promote the importance of adapting our planting philosophy to accommodate the changing climate. The designer of the Food Forests garden, Marina Lindl, told me how helpful it had been to consult with Tom when preparing for the show. Sadly I didn’t photograph her garden which highlighted the idea of multi-layered planting from fruit-bearing trees down to root crops. I admired an attractive plant with purple leaves which she identified as tree spinach, Chenopodium giganteum.

I had a lovely surprise when I moved across the Long Water to where most of the show gardens were located. Manning The Climate-Forward Garden designed by Melanie Hick, was Emma Whitten, one of my fellow students from the class of 2017 of the RHS Level 2 Practical Horticulture course at Capel Manor’s Regents Park branch. A garden designer and landscaper herself, she and Melanie often work together on projects. This is a front garden where slightly raised beds surround a porous gravel area designed as a soakaway for sudden downpours. Within half an hour of chatting to Emma in bright sunshine, which showed off the colourful planting scheme wonderfully well, the heavens opened to an intensely heavy thunderstorm. Just the weather with which this garden and the Ripple Effect Garden were designed to cope.

I’ll close this post with an image from the Strive and Thrive resilient pocket planting . This vivid tapestry will be re-planted at a girls’ care home in Ealing. As I left the show on Sunday evening, the pockets were being emptied and whilst it was sad to see such beautiful creations dismantled, it was good to know they were all going to have permanent homes where their messages of resilience in the face of the challenge of climate change will continue to resonate.

Strive and Thrive

Next time I’ll report on more highlights of the show and my wonderful afternoon volunteering in the seed shop section of the Plant Heritage stand in the Floral Marquee.
