This year marks the Chelsea Flower Show's 100th birthday. Chelsea has always showcased gardens by top designers as well as new plants from around the world. The show's traditions endure, but one change is in the funding of the gardens. Jane Owen, Chelsea gold medallist and editor of House and Home, looks at the role of big business in horticulture and asks whether Chelsea still has relevance.
