Prefers full sun but can tolerate light shade. Fairly adaptable about moisture conditions and soil types.


The nuts of the American hazelnut are edible, nutritious, and naturally taste quite sweet, but are smaller than those of other species which are most commonly cultivated.

This plant is occasionally cultivated as a landscaping plant.

The native Corylus cornuta overlaps somewhat with this species, although it has a more northerly distribution and occurs mostly in the Appalachians in the south of its range.

The introduced Corylus avellana, or common filbert, one of the main cultivated species, has become established in the wild on a few sites across North America.
