Irises provide spectacular focal points in a mixed border, by or in water, among shrubs, in the rock garden or in beds by themselves. In this illustrated handbook, the authors show how irises will grow in almost any conditions and how, even in a small garden, irises can be planted to provide flowers for much of the year. The different types of irises are described in detail and advice is given on where and how to grow them. Propagating, hybridizing, the control of pests and diseases, and selections of recommended cultivars are also covered.
