The Green-headed Coneflower is a sunflower-like, native, perennial wildflower with a branched leafy stalk. It grows five to eight feet tall. The stemmed flowers are at the top of the stalk. Each yellow flower is two to three inches across, with cone-shaped, greenish-yellow centers and six to 12 back-tilted rays. The basal and lower leaves are up to 10 inches long with three to seven toothed lobes. The upper leaves are much smaller, un-lobed and toothless. It grows in moist, slightly acidic soil, and spreads rampantly by underground stems. It likes sun to part shade. Green-headed Coneflowers grow in fields, ditches, and prairies. (SF)
