Other names and notes	(Wild Goldenglow; Tall Coneflower; Cut-leaf Coneflower). The flower heads can be 2 1/2 to 4" wide with drooping rays, 6 to 10. The central disk is greenish-yellow before flower maturity. The lower leaves are pinnately divided into lobed leaflets that are irregular and distinctly different from the Gray-headed Coneflower. Stems can reach 7+ feet in height. The central dish turns dark brown at full maturity, just like Gray-headed Coneflower - leaving the leaves to distinguish quickly between the plants. Best in full sun and somewhat moist soil.
