From Jefferson's founding garden, Monticello, to Martha Stewart's Turkey Hill, American gardens have been revealing self-portraits that reflect their owners aspirations and anxieties, cultural legacies and passing fashions. In his far-ranging survey, designer and historian Graham unveils the aesthetic, political, psychological, and ethical dimensions of the American garden. This is a world in which hedges, lawns, parks, and cemeteries are revealing displays of national identity, class distinction, and political correctness. Our gardens are a pastiche of classical pastoral ideals, the 19th-century European grand tour, and the distinctly American tension between our democratic ideals and aristocratic pretensions. Graham is able to gently mock the fashions of history while astutely observing that we are still as vulnerable to gardening fads today. After more than 250 years, the American gardening tradition has bequeathed to us treasured public parks, suburban sprawl, Kentucky bluegrass lawns in the desert, and kitchen gardens at the White House. Graham's history is a fascinating and illuminating tour of this American landscape. Includes extensive notes and bibliography. More than 70 color and b&w illus. (Apr.)
