Forests of sugar maple-basswood, oak-hickory, hickory-basswood-white ash, maple-birch-hemlock, red pine-aspen, oak-basswood; clay bluffs, river flats, stream terraces, thickets. Rather uncommon and local, with most of our specimens coming from a small portion of the Driftless Area, the southeast counties, the northeast counties near Green Bay, and north central Wisconsin; scattered elsewhere. The distribution of P. nigra in the state deserves more attention. The flowers are often pinkish tinged compared to the white or off-white color of P. americana.
