Le Manoir aux Quat'Saisons, Oxfordshire
Raymond Blanc took over this historic Oxfordshire manor house in 1984 and turned it into a 32-room hotel and a two Michelin-starred restaurant. For much of the year the kitchen is stocked with produce from Le Manoir's walled garden of 90 vegetable varieties, 70 herbs and a mushroom valley. The scene is embellished with perfect rows of lavender lining immaculate lawns, an orchard and a Japanese water garden.

Barnsley House, Cotswolds
The grounds of this 17th-century, Grade II-listed mansion contain a secret: a temple, giving guests the opportunity to dine amid the resplendent formal gardens. Alternatively, there is the contemporary Potager restaurant, named after the 1950s vegetable garden which still supplies the kitchen. The Cotswold-stone hotel had a sleek makeover last year, with interiors inspired by the gardens in plummy purples, russet, dove grey and rose. Special events for the summer include horticultural talks from guest gardeners.

Swinton Park, Yorkshire
When lakes were dug out at Swinton Park in the 19th century, the coffins of Saxon nuns were uncovered. Now an ancient quarry and orangery add to the atmosphere of this coverted castle. In the spring garden, the gothic theme is replaced with a colourful array of bluebells, azaleas and rhododendrons. A bed of wild flowers is cultivated for decorating the hotel, while produce grown in the walled garden features on the restaurant's menu. And, as well as old-fashioned luxury bedrooms, there is a centrepiece suite built within a turret.
