The RHS Hampton Court Palace Flower Show is the largest flower show in the world. The Show is held in early July, and run by the Royal Horticultural Society (RHS) at Hampton Court Palace in southwest London.

The show features show gardens, floral marquees and pavilions, talks and demonstrations.

Erected on the north and south sides of the Long Water in Hampton Court Park, it is the second major national show after the Chelsea Flower Show but has a different character, focusing more on environmental issues, growing your own food and vegetables and cookery, while also offering opportunities to buy gardening accessories, plants and flowers.

The show at Hampton Court Palace will return in 2027. In 2026 we will hold a new show at RHS Badminton in Gloucestershire, 8th to 12th July 2026
