If I were asked to name one garden that exemplifies everything about the evolution of not only horticulture, but of the very nature of 20th century life in England, it would have to be Sissinghurst Castle Garden. A vast and varied property with roots in Tudor England, once a manor, then a ruin, and finally a life-long project for a modernist who was both a Victorian and a pioneer, it deserves its international reputation. Located in the rolling hills of Kent, Sissinghurst basks in some of the best growing conditions on the island.
