Longhead coneflower is a tough, drought-tolerant prairie native that thrives in full sun and well-drained soils with minimal care. Its distinctive tall, thimble-like center and drooping yellow or red petals make it a striking addition to wildflower meadows and pollinator gardens. Deadhead spent blooms to extend flowering, or leave seed heads for birds through winter.
