The Chelsea Flower Show spans five days in May and is hosted by the Royal Horticultural Society in the grounds of the Royal Hospital Chelsea in London. The show is internationally renowned and attracts visitors of numbers up to 157,000 from all over the world – the attendees are limited only by the 11-acre grounds in which the show is held. Awards categories are Flora (for garden and floral exhibits), Hogg (exhibits of trees), Knightian (for vegetables and herbs), Lindley (areas of educational or scientific interest) and Grenfall (photographs and floral arrangements) and winners are recognised in four grades – gold, silver-gilt, silver and bronze. Previous notable winners and attendees have included the first suspended garden which was created by Diarmuid Gavin alongside James May’s “Paradise in Plasticine” which was the first all-plasticine garden. 2010 saw the first year which Taiwan was invited to compete, where the country’s Orchid Growers Association showed rows upon rows of exotic orchids from Taiwan.
