A concise introduction to each genus provides essential details of botanical family, native habitat, number of species, and the ornamental qualities for which the plants are grown, together with succinct advice on cultivation, propagation, and pests and diseases. Specially commissioned photographs closely integrated with the plant descriptions, capture the beauty of nearly 6,000 plants. The full diversity of growth habits within a genus is shown wherever possible, and special close-up panels illustrate the range of flower colors and shapes. A comprehensive introduction and glossary guide beginners and experienced gardeners alike to a greater knowledge and understanding of the key elements of plant classification, anatomy, and cultivation.
