The 2009 SIXTH EDITION is a major revision with expanded descriptions of former entries, over 2000 new species and cultivars, trademark names and patent numbers, as well as all species, subspecies and variety names verified using the GRIN taxonomic database (germplasm resources information network) and other sources. The book is rich, accurate, substantive, and written in Dirr's engaging style.

This new edition includes notes and observations from Dr. Dirr's sabbatical to Hillier Arboretum in England, which holds the greatest collection of hardy woody plants in the world. Additionally, while on sabbatical the author visited and studies woody plants at 112 gardens and nurseries. Dr. Dirr interacts with the American nursery industry and, in addition to visiting the nurseries, travels to the major nursery trade shows to learn what is new.

Professor Dirr covers hardiness, growth rate, habit, foliage, fruit, flowers, size, propagation and much more. Plants are listed by scientific, common and family name. Commonly referred to as the "bible of the industry," every professional should have this book on hand. 1325 pp. B/W, line drawings, Index. Hardcover. ©2009
