Green-headed Coneflower, Tall Coneflower, Cut-leaved Coneflower, Goldenglow, Rudbeckia lanciniata L., Native Minnesota Wildflower plant, Eloise Butler Wildflower Garden

(Wild Goldenglow; Tall Coneflower; Cut-leaf Coneflower). The flower heads can be 2 1/2 to 4" wide with 6 to 10 yellow drooping rays. The central disk is greenish-yellow before flower maturity at which time it turns dark brown, just like Gray-headed Coneflower (Ratibida pinnata ) except the Gray-headed has a taller central disk. The leaves can also be a distinguishing characteristic between the two plants. Flower bracts are of unequal length, pointed, with whitish hair at the tips and stick out between the yellow rays. The flowers of the central disk have a yellow corolla, five lobes and 5 stamens and mature to a dry seed. The lower leaves are pinnately divided into lobed leaflets that are irregular and different from the Gray-headed Coneflower (see comparison below). Upper leaves will have fewer lobes than basal leaves. Stems can reach 7+ feet in height, are smooth and branch near the top into multiple flower heads. Best in full sun and somewhat moist soil. The genus is named after the Swedish father and son, - O. J. and O. O. Rudbeck, who were professors of botany and predecessors of Linnaeus.
