This comprehensive volume, commissioned by the International Dendrology Society, covers more than eight hundred tree species that have been introduced to cultivation in the United Kingdom, Europe, and North America in recent decades. Up until now there has been no comparable source of information. Featuring horticultural notes from a network of growers and enthusiasts, backed up by data from recent scientific studies, the book presents a remarkable amount of information in a fashion accessible to amateurs as well as specialists. More than one hundred line drawings and nearly six hundred photographs--many portraying rarely seen trees--offer aids to identification. Introductory chapters covering conservation and modern techniques of tree-growing, and a comprehensive glossary and bibliography, round out the volume and make New Trees incomparable--and indispensable.
