The Garden as a Dye House — Chelsea Flower Show 2026

The garden was, for much of human history, also a dye house — the madder root, the weld stem, the woad leaf giving fabric its colour long before a chemist ever entered the picture. It is worth remembering that the garden was the first step in getting dressed. So it feels apt that this issue, themed Flower, landed at the same time as a particularly textile-rich edition of RHS Chelsea. If you have been looking for a reason to go, this year there is a particularly good one.

Running from 19–23 May 2026, this year's Chelsea Flower Show features gardens that blur the boundary between horticulture and craft. For anyone curious about natural dye, plant pigment or the living origins of the colours we weave and wear, there is much to discover.

The RHS and The King's Foundation Curious Garden

The standout garden for textile minds this year is the collaboration between the RHS and The King's Foundation, designed by horticulturalist and television presenter Frances Tophill. At its heart sits a beautiful oak-framed building — a 'museum of curiosities' — filled entirely with the plant world's extraordinary contribution to everyday life: fabrics woven from plant fibres, cordage, dyes, pigments, dried flower displays, ferments, balms and infusions. It is, in the very best sense, a garden that thinks like a maker.

The planting is equally purposeful. Dye beds, cut flower beds and vegetable beds sit alongside ponds and pollinator-friendly planting, with every species chosen for both beauty and function. Coreopsis tinctoria — a reliable and vibrant dye plant — features prominently, alongside delphiniums grown at RHS Wisley in honour of King Charles III's well-known love of the flower, and a mulberry tree, itself historically inseparable from the story of silk.

Championed by King Charles III, Sir David Beckham and Alan Titchmarsh, and designed by Frances Tophill, the garden also celebrates artisan craft and skills: apprentices from both the RHS and The King's Foundation helped bring the planting to life, and a stunning artist's easel was created by alumni of The King's Foundation's furniture school. No man-made materials were used in the construction, which stands as a subtle yet radical commitment in a world of temporary show gardens.

After the show, the garden will live on at a college where dye plants will pass directly to fashion students, and herbs and vegetables to catering students. A garden with a second act — exactly as it should be.

Also Worth Seeking Out: Washday Hues — Sparsholt College

A little further along the showground, Sparsholt College's Washday Hues garden offers a more focused deep-dive into the natural dye process. Anchored by a giant washing machine and a washing line hung with naturally dyed garments, the garden walks visitors through the journey from plant to pigment, flower to fabric. Developed in collaboration with ELKA, a Hampshire-based weaving and natural dye studio, the planting draws on the great European dye tradition: madder for red, weld for yellow, woad for blue. It is hands-on, educational, and for those of us who have spent hours over a dye pot, deeply satisfying to see given space at the world's most famous flower show.

Chelsea 2026 feels like a lasting moment for dye-plant species. Not a passing trend, but one that steeps the history of botanical pigmentation into the natural order of things. Go, look closely at the plants, and let the garden remind you where colour truly begins.
