![]() | Dahurian Birch - Betula davurica [1] Native to Manchuria, Northern China and Korea. [Family Betulaceae - Alders, Birches, Hornbeams] [Trees Table of Contents] |
These are autumn colors on October 19th. |
Native to Northern China, Korea, and Japan, Dahurian Birch is hardy to zone 5. Grows to 60' tall, deciduous, forms a rounded canopy with spreading branches and single or multiple trunks. Casts light shade. Dark green leaves 2" to 4" long, Very showy and interesting bark, similar to B. nigra bark. A good lawn tree that is easy to grow. Dahurian Birch is resistent to Birch leafminer (Fenusa pusilla), a small sawfly whose larvae feed on tissue between the upper an lower leaf surfaces. Birches attacked by this insect may show no symptoms of decline for years after being attacked, but repeated leaf loss year after year can be fatal. [2] |
The birches have long been popular ornamental trees in America, chiefly in the northern United States and Canada. Several are native Americans, but many species have been introduced from Europe and Asia. In general, they are graceful trees, the most popular being those with white bark on trunks and larger branches. Some of the others are very serviceable, either because they will grow well in wet soil or because they will exist as well as any other trees, or better, in dry, poor soils. |
