In the central to southern United States (Ohio to Michigan to Iowa south to Louisiana and Georgia), damp grasslands, meadows, and open woods are home to the coarse, rough-haired perennial Echinacea purpurea, sometimes known as purple coneflower. It usually reaches a height of 2 to 4 feet. Over the course of the summer, showy purple coneflowers that resemble daisies (up to 5 inches in diameter) bloom on stiff stalks covered in rough, oblong to broad-lanceolate, dark green leaves. good dried or freshly cut flower. The stems of the dead flowers will stand upright well into the winter.
