Discussion

Celtis occidentalis is valued as an ornamental street tree because of its tolerance to drought.

Native Americans used decoctions prepared from the bark of Celtis occidentalis medicinally as an aid in menses and to treat sore throat (D. E. Moerman 1986).

This is a highly variable species. Segregates named as varieties follow an east-west geographic gradient and are based primarily on leaf size, shape, and pubescence.
