The RHS Chelsea Flower Show, formally known as the Great Spring Show, is a garden show held for five days in May by the Royal Horticultural Society (RHS) in the grounds of the Royal Hospital Chelsea in Chelsea, London. Held at Chelsea since 1912, it is the most famous flower and landscape gardens show in the United Kingdom, and perhaps in the world, attracting visitors from all continents.
Highlights to the Chelsea Flower Show include the avant-garde show gardens designed by leading names with Floral Marquee at the centrepiece. The Show also features smaller gardens such as the Artisan and Urban Gardens.
