Timber for leading UK plant conservation charity Plant Heritage’s first RHS Chelsea Flower Show garden has been donated by Grosvenor TimberWorks.

The Plant Heritage Missing Collector Garden is displayed at the RHS Chelsea Flower Show 2026 – claimed to be the world’s most famous flower show – which takes place from Tuesday 19 May to Saturday 23 May 2026 at the Royal Hospital Chelsea, London.

Grosvenor TimberWorks, based at the Eaton Estate, Cheshire, produces specialist products that are designed to enhance bespoke projects using high‑quality and characterful British timber from trees grown in Grosvenor’s sustainably managed woodlands across its UK rural estates.

The business, which launched this year, has supplied all the timber for the garden, including 50 garden sleepers as well as premium oak setts for the flooring – part of a new collaboration with Allgreen, of Yeovil, Somerset.

Rupert Waters, General Manager, Grosvenor TimberWorks, said: “We bring together sustainable woodland management and specialist timber to support distinctive, design-led projects – and it’s hard to imagine one more unique than this. As part of an organisation known for excellence in land management and conservation, we are delighted to support Plant Heritage in safeguarding cultivated plants for future generations.”

Grosvenor TimberWorks’ specialist products include premium flooring, worktops and cladding to detailed joinery and structurally graded timber. It has access to diverse native species, each offering distinct character and unrivalled provenance.

“We’ve supplied oak setts in collaboration with Allgreen, creating a natural cobble effect using British timber from our UK estates,” added Rupert.

“We’re pleased the garden will be relocated to Chester Zoo, close to our mill, where we’ve supported a number of exhibits and wider nature restoration work.

“The garden is one of several major projects we’re supporting this year, including the transformation of Grosvenor Square Garden, London – one of the most significant private investments in public green space for a generation.”

Plant Heritage is the UK’s leading conservation charity for garden plants and home of the National Plant Collections.

Its garden comes at a pivotal moment for plant conservation. The charity’s Threatened Plants Programme has found that more than half the cultivated plants grown in the UK or Ireland in the past are no longer available to buy. One in six plants have been found growing in just one or two places, or nowhere at all.  

Gwen Hines, Plant Heritage chief executive, added: “We hope to inspire more people to join our growing community in safeguarding our nation’s favourite plants. Whilst plants in your garden may appear safer than those in the wild, they can still be at risk, so it's crucial that we protect our garden plants.”
