These gardens of obsession are visionary, magical, beautiful, dreamy, witty and bizarre - all personal realizations of driven, all-consuming fantasies in the garden, representing all classes and all economic resources. These gardens are metamorphoses of dreams into garden realities. They use all sorts of materials, and range from large rocks shaped by Prince Orsini in the 16th century into Renaissance beasts below his villa near Rome to 20th-century plastic flowers floating in green corrugated sheeting in the front garden of Clifford Davis's terrace house in Blackpool. There are gardens that lie in the jungles of Mexico, a back garden in Chartres, France, a rock garden in India, and many Edens and paradises in the USA, as well as Holland, Spain, Scandinavia, South Africa and Australia.
