With more than 5 000 species and varieties of plants, the Gardens of Valloires thus present one of the most important collections of shrubs in France. In the majority, these plants originate from China and Japan; they all have the particularity of being resistant to lime, as the pH of the soil in the Gardens of Valloires is higher than 8.5. The reputation of Valloires is largely due to its immense rose garden which associates amongst others, a very extensive collection of old-fashioned and wild roses.       A garden signed "Gilles Clément" : In Valloires Gilles Clément, a renowned landscape architect, created a perfectly designed garden that unites the natural environment and is intended to be resolutely educational. For the first time, a landscape designer proposed for an historic site a modern plan that was not a pale copy of an ancient garden. Valloires is the first important work by Gilles Clément who later created the Rayol Garden, the André Citroen Park and the Planetary Park.       A garden is in a perpetual state of transformation: In fact, because a garden is never finished, each year, on a regular basis, new plantations are created at the Valloires Gardens. Gilles Clément regularly plays an active part in the new developments at Valloires, where he has just completed one of the most original plantations ever: the Evolutionary Garden. Anecdote : In 1987, during some works, the very unfavourable meteorological condition obliged us to call in a helicopter to put the stairs in place.
