Iris - Graeme Grosvenor

Graeme Grosvenor is one of the world's leading authorities on the iris and he has endeavoured to make this book the world's most comprehensive and up-to-date on the subject. For those captivated by the gentle beauty of the iris this book offers a wealth of information. It contains a spectacular panorama of colour plates covering current popular cultivars as well as other superb new ones. The text elaborates on characteristics of each of the cultivars and explains propagation and growing points associated with each of them.
Specific information on particular iris cultivars is easily comprehended because each is presented against a thorough coverage of the whole iris division of the genus into the subgenus level: bulbous, tuberous, and rhizomatous. Within each group, he defines further subcategories; for instance he defines within the rhizomatous subgenus the characteristics of the bearded, beardless and crested groups.
