Propagation

Seed Treatment and Storage: Store seeds dry then moist cold stratify for 30-60-90 days. Germinate at 70°F.

Biocultural Value

The Chippewa reserved musclewood for the main posts supporting the ridgepole in tents. Medicinally, the tree was typically used in the form of a bark chip infusion as an antidiarrheal, urinary aid, tuberculosis remedy, and skin wash.

Wildlife Value

An assortment of insects feed on American hornbeam foliage, wood, and sap, including the caterpillars of the eyed Baileya moth (Baileya ophthalmica), woodboring beetles (Agrilus spp.), plant bugs (Lygocoris spp.), an aphid (Macrosiphum carpinicolens), and several leafhoppers (Eratoneura direpta, E. triangulata, and Erythridula modica). American hornbeam nutlets are eaten by several kinds of birds and squirrels and are a preferred food source of the ruffed grouse (Bonasa umbellus). Catkins, buds, twigs, and foliage are also consumed to a limited extent by browsers and gamebirds. Some bids use the tree as nesting habitat, either building among its branches (e.g. the wood thrush) or taking up residence in small cavities of older trees (e.g. chickadees).
