The Kent-based designer and plantsman was joined on his silver gilt-winning Great Pavilion exhibit this year by children from St Leonard's School in Streatham, London, where he will give out plants, along with a school in Rochester and another school to be confirmed.

Platts said: "My biggest memory of Chelsea was those children showing such knowledge; I was amazed. I am going to visit them at school to bring them plants and talk a bit more. I will take some simple flowers as I think they already grow a lot of their own vegetables."

Roger Platts Garden Design & Nurseries supplied plants to three of 2009's Chelsea small gardens.
