As the gates open at this year’s RHS Chelsea Flower Show, Project Giving Back is reflecting on five years of funding gardens for good causes at the show. In all, 63 gardens supported by PGB are now relocated in communities around the UK.To help celebrate its final year, and to create a space for conversation about the future of creative philanthropy in the UK, Project Giving Back has a garden of its own. Kendra Wilson spoke to designer James Basson, along with PGB’s CEO Hattie Ghaui, to find out more.

The RHS Chelsea Flower Show has a way of grabbing the nation's attention, yet one of its most key players in recent times has never yearned for the spotlight. As a grant-making charity, Project Giving Back is busy promoting the good causes of other charities — as well as the horticulture industry — on the generous stage that is RHS Chelsea. In its fifth and final year at the show, PGB can be forgiven for doing a bit of throat-clearing, in presenting its own garden. Being talked about is part of it, but the Project Giving Back Garden is also a celebration of its achievements in creative philanthropy, through the prism of a memorable garden. Designed by returning Chelsea virtuoso James Basson and featuring red, sandy cliffs at five metres high, it is located at the top of Main Avenue and will be hard to miss.
James Basson took away a gold medal and Best in Show from his last outing at Chelsea in 2017, and like other designers who have aced it, he wasn't thinking of returning. But the idea of "giving back" has been a draw for an impressive array of Chelsea stars, persuaded by PGB's funding model that is tied to the relocation of every show garden, for a lasting impact on communities. Who can forget Cleve West's 2023 return, with an emotive, 'abandoned' garden for Centrepoint? The charity, and garden, still see his active engagement.
James lives and works in Provence, making gardens that are integrated into the needs of the local landscape; if there is no natural water source, then the garden is designed not to require water. The inspiration for his Chelsea garden is a place in Roussillon, a post-industrial, former mine for extracting ochre pigment. "Humans have been there, they've done their thing, and then the land is recovering," explains James. "And what's remarkable is that it's recovering really fast." The rocks there are relatively soft, eroding in interesting ways. "Within 60 years, the whole thing has become a kind of amorphic shape that is really extraordinary."
Within this dry landscape there is a lot of diversity, which will be reflected in the show garden. In the original location that was James' first inspiration, plants are dense where there is more shade, thinning out to nothing in exposed, sandier areas, and there is a garden within that. "It's a gardened piece of landscape, near a house," he says. "It's a little gem, that someone goes into every now and then and just kind of harbours the vegetation, to make enough room for a table and chairs, and a place to be within this extraordinary landscape."

The plant list for the PGB garden is not composed of 'show' plants; in fact, there are no cultivars at all. Everything can be found already growing at the Roussillon ochre mine. Expect to find at least 24 pine trees and 40 dog roses, plus the tiniest species, which almost ask to be examined on one's knees (common whitlowgrass has petals that are 3-millimetres long). Prettiness and plant perfection is not the aim but there is natural elegance; native flowers include luminous field gladiolus, starry, white St Bernard's lily and small lilac drumsticks of Caucasian crosswort. "Because the land changes from one step to the next, from calcareous into a more acid sand landscape, the vegetation is dramatic, it's very showy. Hopefully, the vegetation will do the show thing, while demonstrating what can grow in that kind of material."
The other striking thing about the mines is their colour, an intense, and reverberating ochre. In varying hues of gold, orange and red, Guy Valentine and his team at Clayworks have used a lime render to cover metal structures that represent cliffs, even at the front of the garden. Because the original rocks are made of what is essentially ochre pigment, the show rocks need to resonate. Previous form has shown that James is adept at balancing spectacle with subtlety. "The lime render will be a very strong colour, using natural ochres," he explains. "The structures will be inspired by the rock, without trying to make a direct copy. Kind of like a Cézanne painting of those rocks, but in sculptural form."
The Project Giving Back garden is a 'feature garden' and will not be judged. This gives the designer a freer hand, and nobody will be marking him down for using, say, too much rock (two thirds of the ground plan is unplanted, sandy substrate). There is method to this; it's a way of challenging first impressions. Visitors will be drawn over by the theatre of the ochre-red cliffs, before looking down at what is going on at their feet. "There's a huge change in scale," explains James, "from the massive rock structures to the very delicate, dainty vegetation which manages to survive in this material."
Not everyone will like it. "I have no doubt that for some people who visit Chelsea, it won't speak to the aesthetic they're looking for," says Project Giving Back CEO, Hattie Ghaui. This is grist to the mill; PGB might keep a low profile, but it's not the sponsored gardens' intention. Controversy has benefitted charities, with the best-in-show, Rewilding Britain garden in PGB's debut year, a famous example. The ability to generate Chelsea hoo-ha, combined with the returns from more controllable fundraising events held by charities on the gardens during show week, has been a PGB success story. Through their Chelsea gardens alone, charities sponsored by Project Giving Back have been able to raise £20 million over the last four years.
Two thousand plants, grown by Kelways, will be relocated from the Project Giving Back Garden to a volunteer-led greenspace in Cheshire, the Wonky Garden. Begun as a means of cancer recovery for its founder, Angela Hayler, it has grown into a garden that supports the wellbeing of a community. The theme of community and teamwork runs through all PGB-sponsored gardens, in both their first and second acts. Project Giving Back's 64th and final garden at RHS Chelsea has been built by Mark Whyman Landscapes and planted by professionals and skilled volunteers, led by horticulturalist Marc O'Neill. Its theme is, in the end, self-explanatory. "Anyone who does Chelsea owes it back, because of the people who help you make a garden," says James. "Everyone puts in 200 percent."
