This is the first comprehensive pictorial look at the American mountain flora from the southernmost Rocky Mountains to the Brooks Range of Alaska. Approximately 650 species in 54 genera are discussed, with many subspecies, varieties, and hybrids also described. Intended to be as useful for the gardener as the traveler, each entry concludes with a discussion of propagation and cultivation information, as well as warnings about pertinent pests and diseases. The 495 color photographs are not only lovely but they also give the reader an idea of the range of alpine plants growing in North America.
