Irises: A New Zealand Gardener's Guide by Pamela McGeorge
The colour and variety of irises mean that there are plants to suit all tastes and climates. Irises are perennials that will reward gardeners with years of pleasure. They are ideal for both large and small gardens, and there are some that thrive in containers and others perfect for rock gardens. This practical book includes bearded, bulbous and beardless irises, and Evansia or crested irises. Also contains sources, bibliography, glossary and index.
