Chris Francis, wholesale and retail director of Hillier, said: "At Hillier, we have decades worth of great memories connected to Chelsea.
"The Memory Tree in our exhibit is a way of celebrating this and also inviting others to share their garden related memories. Visitors to our exhibit are welcome to add their memory to the book that we will keep below the Davidia involucrata, and to also sign and hang special copper tags on the tree. By the end of the show week, we hope to have a book packed full of gardening memories and a tree covered with tags."
The Memory Tree is an initiative being supported by Hillier’s charity partner, the Wessex Cancer Trust.
Alan Titchmarsh will be the first person to place their garden memory on the tree. Other famous faces, garden designers and personalities will also be invited to leave a memory on the tree on unique wooden tags, which will be auctioned after the show to raise funds for the Wessex Cancer Trust.
