==Description==
''Echinacea purpurea'' is an herbaceous perennial up to tall by wide at maturity. Depending on the climate, it blooms throughout spring to late summer. Its cone-shaped flowering heads are usually, but not always, purple in the wild. Its individual flowers (florets) within the flower head are hermaphroditic, having both male and female organs in each flower. It is pollinated by butterflies and bees. Its habitats include dry open woods, prairies and barrens, as well as in cultivated beds. Although the plant prefers loamy or sandy, well-drained soils, it is little affected by the soil's pH.〔(Flora of North America, Eastern purple coneflower, ''Echinacea purpurea'' (Linnaeus) Moench, Methodus. 591. 1794. )〕
