Kew's IncrEdibles festival will host pleasure boating at the garden for the first time in more than 100 years.
The water will be dyed Mediterranean blue and the boats will sail in front of Kew's Palm House, around a giant interactive floating pineapple created by ‘food architect’ Bompas & Parr.
The festival will invite visitors to reconsider the 12,000 plant species that humans can eat.
Other features include giant inflatable carrots, a Rose Garden Tea Party, a Rainforest Larder (Palm House) with more than 60 tropical edible plants, a Global Kitchen Garden with more than 90 edible plants and Student Vegetable Plots, where Kew diploma students will on hand to give tips on how to grow vegetables.
IncrEdibles runs from 25 May to 3 November. Boating ends 1 September.
