Every year, for five days in May, the grounds of the Royal Hospital, Chelsea, are transformed into the fabulous show gardens, inspirational small gardens and vibrant horticultural displays that make up the world’s most famous flower show.

The RHS Chelsea Flower Show is the first event of the summer season and showcases the finest examples of horticultural excellence, created by the best garden designers, plantsmen and plantswomen. It sets the latest gardening trends, is plant breeders favourite place to launch new plants and features the newest and most desirable gardening products.

Designers from across the globe apply to create show gardens and, with a limited number of spaces, only very special designs make it to the show. A committee of horticultural experts meet three times to assess the applications before selecting around 20 show gardens, which will create the impact and spectacle that Chelsea is renowned for.
