Casual visitors to this Loire Valley chateau will not guess that its "quintessentially French" potager - albeit realised on an almost surrealistically massive scale - was created in the early 20th century by a Spanish-born doctor and his American wife, utilising what might be described as a relaxed attitude to authenticity. None of that matters. The garden is a visual, sensual triumph, with the vegetables in the nine squares of the formal potager garden chosen as much for their looks as their culinary value. This is the garden that made the ornamental cabbage into a cult in the 1990s. Decorative structures called berceaux (like large wooden pergolas) are sited at the corners of the potager, covered in roses, while beyond this focal space are formal parterre gardens containing clipped evergreen hedges, fountains and exuberant herbaceous plantings. This is a garden that is beautiful -and unashamedly good fun.
