Common in wet prairies and moist prairie depressions, often growing with prairie Cord Grass. Usually up to 4' tall with smooth, hairless stems and leaves. The leaves are laternate, finely and regularly toothed along their edges. The largest leaves can be 6" long and over 1' wide, but are often much narrower. There are numerous tiny pits on the underside of each leaf. Flower heads are in a dense, rounded cluster at the top of the plant. Each flower has 5-petaled, tubular corolla and 2 protruding, threadlike style branches.

Blooms: July to September.
