Eastern purple coneflower prefers dry soil. It is similar in appearance to other Echinacea with purple flowers. To tell them apart, look at the leaves. Smooth coneflower (E. laevigata) has lance-shaped leaves while Eastern purple coneflower leaves are heart-shaped. Broader, shorter lanceolate leaves along the stem differentiate E. purpurea from Black sampson / Purple coneflower (E. angustifolia).
Eastern purple coneflower attracts butterflies and bees.
