The garden will be the largest at Hampton Court at 20x8m. Visitors can view the garden at 360 degrees - the first time this has been allowed at the show.
The garden takes inspiration from the progression to retirement. Plants will be sourced from Italy to accompany those grown at his own nursery.
Featured plants include Lavandula, Echinacea, Artemisia and Salvia. Custom-made Chilstone panels are also incorporated into the design, to allow for separation and add an aperture for people on the outside to get a glimpse though to the main part of the garden.
He said: "I’m excited to be back at Hampton Court and with a garden I feel exceptionally proud of. At 21, retirement is not something that is in the forefront of my mind so it’s been a challenge making sure the three stages in the garden (youth, maturity and retirement) capture these moments in time.
"I’m hoping the wide variety of tranquil plants, in particular Lavandula and Echinacea, raised borders, custom made Chilstone panels and pavilion will illustrate these key life stages to visitors and that they will be able to relax and take in the senses the garden stimulates."
