"Invisible Gardens" is a composite history of the individuals and firms that defined the field of landscape architecture in America from 1925 to 1975. The major protagonists include Thomas Church, Roberto Burle Marx, Isamu Noguchi, Luis Barragan, Daniel Urban Kiley, Stanley White, Hideo Sasaki, Ian McHarg, Lawrence Halprin and Garrett Eckbo. The authors look at unbuilt schemes as well as actual gardens, ranging from tiny backyards and play spaces to urban plazas and corporate villas. The result is a record of landscape architecture's cultural contribution during the years when it was acquiring professional status and struggling to define a modernist aesthetic out of the startling changes in postwar America.
