A coarse, sunflower-like perennial grows to 4-6’ tall on rough, erect stems sparsely clad with oval leaves. Individual plants often display a spindly appearance. Flower heads (to 3” diameter) featuring light yellow rays and greenish center disks bloom in late summer to early autumn on the upper part of the plant. Easily grown in average, medium moisture, well-drained soils in full sun/part shade. Tolerates some drought once established. Plants may be cut back in early summer to reduce mature plant height.
