A central part of a visit to any botanical garden is the conservatory, an enormous glass structure that houses a wide variety of exotic flora. America has an abundance of examples; many of which have been designated National Historic Landmarks. This book looks at garden conservatories in the United States from the Victorian-era structure in Golden Gate Park in San Francisco to the Quad city conservatory in Rock Island, Illinois. Twenty-five conservatories are prented in detail through colour photographs and descriptions.
