The Earl and Countess of Wessex toured the feature Queen’s Green Canopy (QGC) garden at the event, designed to highlight the importance of trees and woodlands to the environment.
Asked to take a walk on their own through the garden by photographers, the Wessexes smilingly obliged.
Afterwards Sue Biggs, director of the RHS, joked: “Well was that romantic enough for you? Did you enjoy it?”
Sophie - wearing a cream Victoria Beckham knitted dressed with slashed sleeves and wedge heels - joked, with one eye on the media: “Oh yes, it’s lovely with no-one else around!”
The couple were accompanied by several other members of the Royal Family - Princess Anne, The Duke and Duchess of Gloucester, Prince and Princess Michael of Kent, and Princess Alexandra - all attending their first Autumn RHS Chelsea Flower Show at the Royal Hospital Chelsea due to the pandemic.
Visitor numbers are limited to 142,000 people over six days, compared with 168,000 over five normally. The royal party still seemed to enjoy themselves hugely as they toured the site in the grounds of the Royal Hospital, Chelsea.
Sophie was taken aback by a giant pumpkin grown by Ben White from Maldon, Essex. “Wow!” she exclaimed.
Meanwhile Princess Anne impressed the designer of the Queen’s Green Canopy garden with her horticultural knowledge.
David Dodd said: “I was actually blown away by how much she knew. She immediately knew each tree there and told me how much work she was doing planting trees on her estate [Gatcombe Park].
“There was a cut leaf beech that she immediately spotted, I couldn’t quite believe it.”
“It has been such a privilege to be involved in this garden and to be able to get across to people the importance of trees to our biodiversity.”
THe 2021 RHS Chelsea Flower Show runs until Sunday.
