The 25th Anniversary Garden designed by James Seed, Alex Bell and Claire Potter and sponsored by Clark’s Trees will cover 676m2 and is the biggest ever judged by the RHS.
It is designed to evoke the essence of Malvern, paying tribute to its natural spring water, famous hills and agricultural links.
Rings of grassy mounds and planting ripples are off set by native cherry trees and ornamental borders while swathes of herbaceous plants to complement the hard landscaping.
Wheat runs along a wall to offer a dividing line between past and present, pastoral and floral.
An avenue of beehives and a water feature complete the gatrden.
The Princess will visit the Three Counties Agricultural Society’s Malvern Showground on 7 May where she will be met by the Lord Lieutenant for Worcestershire Michael Brinton and Angela Brinton DL.
Together they will tour the event with Three Counties Agricultural Society President James Hervey-Bathurst.
The delegation will meet longstanding exhibitors and take in the various anniversary celebrations, including a specially commissioned birthday cake make of sweet peas, designed by David Matthewman.
Malvern Spring Gardening Show Manager Doreen Smillie said: HRH The Princess Royal is no stranger to the Malvern Showground and we are naturally delighted that she should choose to honour us with a visit in this special year. We hope to introduce her to some of the many people who have supported the show over the years and have worked tirelessly, very often behind the scenes, to make it the success it is today.
