The RHS Chelsea Flower Show, officially the Great Spring Show, is a garden show held each year on five days in May by the Royal Horticultural Society (RHS) in the grounds of the Royal Hospital Chelsea in Chelsea, London. It is the most famous such show in the United Kingdom, perhaps the most famous gardening event in the world and part of London's summer social season.
Popular parts of the Chelsea Flower Show include the show gardens designed by leading names and the centrepiece of the floral marquee.
The Chelsea Flower Show receives a lot of publicity. It is attended by 157,000 visitors each year (a number limited by the capacity of the 11-acre (45,000 m2) ground), and all tickets must be purchased in advance. From 2005 the show was increased from four days to five, with the first two days only open to RHS members. The show is extensively covered on television by the BBC. An official DVD of the show is produced on behalf of the RHS by Twofour. Several members of the British Royal Family attend a preview of the show, as part of the royal patronage of the RHS. The area of land devoted to show gardens increased steadily between 1970 and 2000 and the show has become an important venue for watching trends. New plants are often launched at the show and the popularity of older varieties revived under the focus of the horticultural world. It is the garden design equivalent of a catwalk at a fashion show.
