Echinacea purpurea (eastern purple coneflower or purple coneflower) is a North American species of flowering plant in the sunflower family. It is native to eastern North America and present to some extent in the wild in much of the eastern, southeastern and midwestern United States as well as in the Canadian Province of Ontario. It is most common in the Ozarks and in the Mississippi/Ohio Valley. Echinacea purpurea is an herbaceous perennial up to 120 cm (47 in) tall by 25 cm (10 in) 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.
