Plant Heritage has conferred its most prestigious honour The Brickell Award on Chris Lane.
Lane has held his National Collection of Hamamelis since 1997 and runs his own nursery, Witch Hazel Nursery, in Sittingbourne, Kent.
The Brickell Award for Excellence in Cultivated Plant Conservation is presented annually in recognition of outstanding work being undertaken by a National Plant Collection on a Collection with Scientific status.
Plant Heritage plant conservation officer Mercy Morris said: "I am thrilled that Chris has won the Brickell Award. He has one of the most well-developed and researched collections, and is truly dedicated to spreading his enthusiasm and knowledge of the genus to others."
"His work on his chosen genera is outstanding, and will contribute substantially to ongoing research into both the cultivation and propagation of woody plants. To hold four National Collections and carry out so much research and development is a huge achievement. I think he is a very worthy winner," she added.
Lane said: "I am very happy and honoured to receive this award and be amongst previous winners who have carried out great work in cultivated plant conservation."
He holds four national Plant Collections: Hammamelis, Wisteria, Amelanchier and Parrotia and serves on the Woody Plant Committee of the RHS.
The award will be presented to Chris Lane on 7 July at the RHS Hampton Court Palace Flower Show by Christopher Brickell at 12.30pm in the Plant Heritage marquee, situated on the North side, marquee PH1.
