The designer has got the go-ahead from the RHS this week for his plan which reflects elements of a large English country estate and explores the important relationship that estate gardens have with their gardeners, as well as the charity’s foundations, which lie in the great country gardens and estates of Great Britain.
Called the Perennial Legacy Garden, it features long herbaceous borders, a pavilion for relaxing and enjoying the garden and a separate walled working garden with gardener’s bothy and nursery beds.
Hervey-Brookes said: "This will be the first time I have created a garden at RHS Tatton Park and it’s an honour to be associated with Perennial for the show.
"Over the past couple of years I have become more aware of the incredible work Perennial does to help horticulturists, and that work has informed and guided my design."
The RHS has called the design "strong and appealing".
Director of marketing Anita Bates said: "We are a strong, unique charity that has been, quite literally, born from the estates and country houses of Great Britain. This garden reflects that tradition of support.
"Paul has taken our brief and created for Perennial a celebration of tradition and a garden that is as inspirational today as it would have been in the 19th Century."
