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.
Echinacea angustifolia blooms late spring to mid summer. It is found growing in dry prairies and barrens with rocky to sandy-clay soils. There are two subspecies:
Echinacea angustifolia subsp. angustifolia is native to central Canada and the central United States from Saskatchewan and Manitoba in the north to Arizona, New Mexico, Texas, and Louisiana in the south.
Echinacea angustifolia subsp. strigosa has a more limited range in Kansas, Oklahoma, Texas, and Louisiana.
Many Native American groups used this plant for a variety of medicinal purposes, including pain relief and relief of colds and toothaches.
