The garden, named after teenager Horatio Chapple who was killed by a polar bear while on an expedition to Svalbard, Norway last August, has won national and international renown.
West, who won best in show at RHS Chelsea Flower Show this year, has built the garden at the Duke of Cornwall Spinal Treatment Centre in Salisbury. Horatio volunteered at the centre during his school holidays and his patient research identified the need for a garden.
"It is a sanctuary for people with spinal cord injury, improving their quality of life during their long stays in hospital," said a spokeswoman. "A team of volunteers called Horatio’s Garden Friends help patients to use the garden."
Patron of the friends’ group is the Countess of Radnor and Horatio’s Garden is a charitable project led by the Southern Spinal Injuries Trust, which supports the people with back injuries in the south and south-west of England.
Horatio’s mother Olivia Chapple and Cleve West will make speeches on 28 September and the Dean of Salisbury, the very reverend June Osborne, will make a dedication.
