Echinacea pallida — pale purple coneflower

Facts

A native of midwestern and southern states, pale purple coneflower is considered to be non-native in New England, where it is recorded from Connecticut, Massachusetts and Maine. It is sometimes grown in gardens, and the roots are used in herbal medicine, as are the roots of eastern purple coneflower (Echinacea purpurea).
