RHS Chelsea Flower Show 2026

Every spring, west London hosts the Glastonbury of the gardening calendar. Across five days, hundreds of world-class growers and garden designers descend on Chelsea’s Royal Hospital Grounds to take part in the floral extravaganza that is the RHS Chelsea Flower Show. More than 400 exhibits show off the green-fingered talent of the world’s finest landscapers and horticulturalists, and shine a spotlight on charities such as Parkinson’s UK, the Trussell Trust and Asthma + Lung UK. Then, of course, there’s the much anticipated (and rather frantic) plant sell-off on the final day of the event when exhibitors put their display plants up for bargain prices.
