Innisfree is a 150-acre public garden in which the ancient art of Chinese landscape design has been reinterpreted to create, without recourse to imitation, a unique American garden. At Innisfree the visitor strolls from one three-dimensional picture to another. Streams, waterfalls, terraces, retaining walls, rocks, and plants are used not only to define areas but also to establish tension or motion. The 40-acre lake is glacial, most of the plant material is native, and the rocks have come from the immediate forest.
