All the Chelsea Flower Show 2025 gardens to see this year – a full list

C6 comes from the chemical symbol for carbon (C), and its atomic number (6). It’s also the name of a garden designed at this year’s Chelsea Flower Show by Joshua Fenton, which sequesters more than 1,200 kilograms of carbon, and slows and stores 450 litres of rainwater. It does that through the use of bio char in the soil and charred oak planters, but also through planting, with fast-growing trees and herbaceous perennials. It’s proof that even a small urban garden can contribute to a type of carbon offset with good design.

Cha no Niwa

Designed by Kazuyuki Ishihara, this Japanese tea garden inspired by the twin themes of communication and harmony, the distinctive design within Cha no Niwa – which literally means “tea garden” – employs stones and plants in thoughtful interaction with one another. Different elevations create a sense of depth and layering, and are influenced by ikebana, the traditional art of flower arranging in Japanese culture. Acer palmatum, Enkianthus perulatus, Iris, Sedum, Hornbeam and Pachysandra terminalis all feature too, as trees commonly seen in the Japanese countryside.

Children With Cancer ‘A Place To Be’

“A place to be happy, carefree, reflective, healed, refreshed, renewed and grounded by the natural world” – the ambitious but ultimately down-to-earth ethos behind the Children With Cancer garden, as you might have guessed, comes from its intended future purpose as a recovery space for, well, children with cancer. Specifically those at Raines Retreat, a holiday retreat in Yorkshire for those affected by the illness. In practice, this means that Tom Clarke and Ros Coutts-Harwood’s garden offers a refuge called the Nest at its heart, amid pink and burgundy planting like Rosa ‘Emma Bridgewater’, Allium ‘Forelock’, and Lysimachia atropurpurea ‘Beaujolais’. Digitalis purpurea ‘Pam’s Choice’ adds a splash or two of white, with green courtesy of wood ferns and moor grass (Dryopteris wallichiana and Sesleria autumnalis).
