There have been gardens at Knebworth House since at least the 17th century, but the present layout dates largely to the Edwin era.

The ornate beds and statues in the Victorian garden were simplified by architect Sir Edward Lutyens with lawns and avenues of pollarded lime trees.

Meanwhile the herb garden was created in 1982 from an original 1907 design by Gertrude Jekyll.

The 28 acres of formal gardens include a maze, colourful borders, trees and a walled vegetable garden.

Managing director Martha Lytton Cobbold said: "We’ve worked with Will, his family, and his team for 30 years now and are delighted that we have reached this milestone anniversary together.

"The Garden Show is a wonderful event to share our delight in gardening in the beautiful grounds of Knebworth Park."
