Japanese Beech

Fagus crenata (FAG-us kre-NAY-tuh)

Family: Fagaceae Non-native Understory

Japanese Beech is a flowering, deciduous tree, with a rounded crown native to Japan. This variety of beech tree tends to have dense, low branches with a tall, stout trunk and smooth, silver-gray bark. The Japanese Beech, in particular, has alternate, simple, toothed leaves with 1 tooth for each secondary vein. The flowers are small and inconspicuous and the fruit, the edible beechnut, is a 3-angled nut inside of a weakly spiny husk. The tree is slow to mature, but can reach a height of 100 feet. Japanese Beech does best planted in well-drained fertile soils in full sun to partial shade. Young trees are shade tolerant, but subject to frost damage and it is best to provide them protection from winter winds. The trees have surface-feeding roots, can cast a dense shade that can inhibit the growth of other plants, and prefer hotter summers. These trees are suitable as a shade tree for homes, parks, libraries, and other municipal spaces. The are typically found in forests or natural area in rich woods, but are most often used as a cultivated tree in an urban landscape. Diseases, Insect Pests, and Other Plant Problems: No known diseases or insect pests. More information on Fagus .
