RHS amabassador Mary Berry will be opening the RHS Wisley Flower Show on 2 September and signing copies of her books.
The show will include the National Dahlia Society and the NAFAS (the National Association of Flower Arrangement Societies) putting on displays of newspaper-inspired floral art.
Nurseries will sell cacti, hostas, dahlias, chrysanthemums, alpines, bonsai, herbs, conifers, lilies, tropical house plants and more. Tradestands will have tools, sculptures, artwork, garden furniture and more.
Wisley curator Colin Crosbie, said: "I am thrilled that the National Dahlia Society Show will be returning to Wisley, as it went down a storm last year. It brings dahlias to the fore when they are looking their very best."
