Rich woods of sugar maple-basswood, often in ravines or on bluffs and talus slopes; also occasionally along roadsides and railroad tracks and in fields. Like Gleditsia, Wisconsin lies at the edge of the range of this species, and it is native in roughly the same areas but extends a bit farther north. It is also widely planted as a street tree but does not seem to escape as readily. Populations outside of this confined range were possibly introduced by Native Americans who used the seeds for food, medicine, and for ceremonial and recreational practices.
