The RHS will reveal the 15 main show gardens on 11 November, an apt date given the expectation that the Royal British Legion will sponsor a garden this year.
London designer Charlotte Rowe is thought to be a first timer in the main avenue, while Hampton Court winner Matthew Childs has been linked with Brewin Dolphin. Victoria Truman has also been named.
Del Buono Gazerwitz Landscape Architecture is linked to The Daily Telegraph garden and former RHS young garden designer of the year Hugo Bugg is said to be designing for the Royal Bank of Canada. Youngster Jack Dunckley is another name put forward.
Chelsea selection panel chair Andrew Fisher Tomlin said: "The great thing is that some of the sponsors have recognised the need to do something different and bring new blood in with new ideas. I often see more exciting ideas from young people with a different take on what gardens can be at these shows than from people who have been doing it for 20 years."
Selection panel member David Dodd of the Outdoor Room added: "Most people who have done it before aren't there this year. There is an element of younger talent. It's going to be exciting."
Sources say that Laurent Perrier has chosen Luciano Giubbilei, while Adam Frost is expected to return with Homebase and Andrew Wilson with Cloudy Bay.
