Echinacea angustifolia (Narrow-leaved purple coneflower or blacksamson echinacea)[2] is a North American plant species in sunflower family. It is widespread across much of the Great Plains of central Canada and the central United States, with additional populations in nearby regions.[3]

Echinacea angustifolia is a perennial herb up to 40 to 70 centimetres (16 to 28 in) tall with spindle-shaped taproots that are often branched. The stems and leaves are moderately to densely hairy. The plant produces flower heads one per side branch, each at the end of a long peduncle. Each head contains 8-21 pink or purple ray florets plus 200-300 purple disc florets.[2]

Echinacea angustifolia blooms late spring to mid summer. It is found growing in dry prairies and barrens with rocky to sandy-clay soils.[2] There are two subspecies: [4][5]

Many Native American groups used this plant for a variety of medicinal purposes, including pain relief and relief of colds and toothaches.[7]
