It is near Market Drayton, on the border between Shropshire, north Staffordshire and Cheshire, with views over the three counties. The original garden is two acres, but the site now extends to 12 and includes a rose walk, an alpine scree with pool, an edible woodland, a winter garden and a waterfall.

Gilbert White’s house and gardens, Hampshire

Naturalist Gilbert White, considered the father of English ecology, lived at the Wakes, an imposing 18th-century house in Selborne, in the 18th century. It has 30 acres of ancient parkland and gardens, restored to their original layout and with views over the Hampshire Hangers and South Downs. In the kitchen garden on Bakers Hill, fruit and vegetable varieties recorded by White are cultivated using period tools and methods. There’s a herb garden and six themed “quarters”, plus follies and a zigzag path through the beech hanger. The tea parlour uses ingredients from the garden, and the house is now a museum.

The three acres that make up Norwood Gardens are on the south side of the Teifi valley. Seven themed areas are set along a central path, including bamboo, alpine, Mediterranean and “lillyish” gardens. After the “bogless bog” and quiet garden, the space opens up, creating a natural progression to the agricultural land and hills beyond. A sunken “dark and light” garden will open this summer.

St Michael’s Mount, Cornwall

This tidal island has an astonishing subtropical garden clinging to its granite cliff face. Thanks to the Gulf Stream, frosts are rare and the rock acts as a giant radiator – absorbing heat by day and releasing it by night. This microclimate means unusual plants thrive, including puya, agave and aloe. More common plants such as rosemary, lavender and coronilla tumble down the steep terraces. The middle walled garden has been newly planted with silvery cineraria and artemisia, broken up with prairie-style plants. Until 1 July, visitors can meet the gardener daily at 1pm or listen to a terrace talk at 11.15am and 3.15pm.
