This native perennial grows up to 6 feet and taller (D). The stems are square (C). Coarsely toothed, opposite leaves are heart-shaped with medium stalks (A). Pale yellow, tubular flowers with 4 protruding stamens and a single forked style are crowded on erect spikes up to 5 inches long (B). The dried plants often remain standing throughout the winter.

Found in woodlands and along roadsides, flowering in August and September. It is uncommon in upland and lowland woods at both Fontenelle Forest and Neale Woods.

Native Americans used the leaves in a compound used to treat poison ivy rash. The leaves were also brewed to make a tea-like hot drink.
