A lovely, small canopy tree with a broad, open, irregular crown and deeply channeled, purplish brown bark that is easy to recognize. Foliage is a dark crimson red in fall. Occurs naturally in sandy, gravelly, and rocky upland soils where it may form pure stands but reaches its best growth on well-drained lowland sites. A good shade tree that does exceedingly well in dry, rocky soil. Acorns are sweet and can be eaten right off the tree.
Very high wildlife value. Acorns are food for turkey, grouse, many songbirds, ground birds and small mammals.
