Conditions Comments: Blue beech works best as an understory tree in low, shady places, though it shows remarkable adaptability to drier, sunnier sites. It will tolerate periodic flooding. Leaves are occasionally attacked by black mold. It is a slow-grower. The European C. betulus is the more widely plant species but has less desirable fall foliage and its trunk is obscured by lower branching.

Benefit

Use Ornamental: Understory tree, Fall conspicuous
Use Wildlife: Fruit-mammals, Fruit-birds.
Use Other: The name Hornbeam has reference to the extreme hardness of the wood - horn"" for toughness, and ""beam,"" an old word for tree. Hornbeam has been utilized for levers and handles of striking implements, but, as it cannot be obtained in large quantities from so small a tree, it is employed chiefly by local tool makers and does not figure as a wood of commerce.
