River banks, stream valleys and ravines, rich moist forests, and rarely drier sites. Usually a medium-sized tree, especially at the northern edge of its range, which includes Michigan.

The leaves are quite variable in size and scabrousness. Hackberry often produces “witch’s brooms” when disease causes proliferation of branch tips.
