A sunflower-like perennial, Green-head Coneflower’s branched, leafy stalk grows 3-10 ft. tall. The stemmed flowers are at the apex of the stalk. Each flowers is 3-4 in. across, with cone-shaped, greenish-yellow centers and back-tilted golden rays. The center cones elongate and become brownish as the seeds ripen. Attractive leaves are pinnately dissected and emerge early in spring.
