Eight local hunts have provided the 25,000 plants that will be sold at Eyford House Plant Sale to raise money for the Countryside Alliance and ABF The Soldiers Charity.
And novelist Jilly Cooper will guest of honour at the event in Stow-on-the-Wold, Gloucestershire on 22 May.
All the plants on sale have been tended by member of the Cotswold, North Cotswold, Heythrop, Old Berks, Beaufort, Warwickshire, Berkeley and VWH hunts.
Charlotte Heber Percy, whose family lives at Eyford House, said: “The plant sale is something we are all passionate about: everyone on the committee supports country sports and the rural way of life. We also support our brave armed forces, so this plant sale is the ideal way for us to boost both causes while providing a fun day out.”
Major General Sir Evelyn Webb-Carter, chief executive of ABF The Soldiers’ Charity hopes the event will be a success.
“We rely on people digging deep and we hope they will here on 22 May so we are able continue our work and live up to our motto, For Soldiers for Life.”
