The stunning Betula, or birch trees, are notoriously difficult to identify despite being one of the major contributors to the beautiful fall foliage famous in eastern North America. With many wrongly named birches appearing in nurseries and arboreta, this new book, the first ever written on the genus, is an important and much-needed work.
The Genus Betula covers all known birches found in North America, Europe, and Asia, along with keys for accurate identification. Chapters include a look at the breeding, cultivation, conservation, and morphology of all species, including several little-known species wonderful for garden and landscape use. The authors present previously unpublished data on recent molecular work and fossils, providing a cytotaxonomic and phylogeographic revision of the Betula genus. The book is accompanied by exquisite specimens of botanical art, including full-color paintings by Josephine Hague, making it a valuable tool for arboriculturists as well as professional and amateur gardeners.
