More than 30 years ago horticultural taxonomist Larry Hatch wondered why there was no updated perennial encyclopedia with all the new cultivars from both Europe and the US as well as rarities from Asia, Australia, New Zealand, and South Africa. Not finding such a work, he created Hatch's Perennials which now spans more than 2000 pages of richly, detailed material.
With 38.6 megabytes and 135 pages on content this volume is one of the core necessities in the series.
This 2017 update now detains new cultivar registrations from the OROC or Open Registration Of Cultivars program.
Cultivars of Woody Plants was started over 35 years ago by horticultural taxonomist Larry Hatch who was concerned that no modern authors were actually cataloging the new cultivars on a worldwide basis. Since the days of Krussman and Bean, no exhaustive reviews with lots of taxonomic and historical detail existed. And those did not have color images of any real size and usefulness. It was time to supplement the old classics and keep it updated every year or two.
