In The Harmonious Garden, Catherine Ziegler describes fail-safe design methods. Even novice gardeners can compose plant arrangements that successfully incorporate color, form, and texture. The first section presents 149 integrated compositions. Ziegler fully describes the plants in each arrangement: Latin name, quantity and size, environment, and USDA zones. Full-color photographs illustrate each composition, and the author discusses the key principles underlying each harmonious design. The second section offers more detailed information with suggestions for successful design combinations.
