This native perennial plant is 1½–3' tall and largely unbranched. The central stem is long, round, and slender; it is hairless near the apex, but sometimes has scattered white hairs near the base. The foliage consists primarily of alternate leaves crowded together near the base of the plant. These leaves are up to 10" long and 2" across. They are lanceolate or oblanceolate, and have smooth margins; sometimes there are 1 or 2 small lateral lobes near the base. Sometimes there are scattered white hairs along the leaf surface, particularly along the mid-rib on the lower side. The upper stem is largely devoid of leaves, and terminates in a single compound flower. This compound flower is 2-3½" across and quite showy. It consists of numerous yellow or yellowish brown disk florets, and 6-10 surrounding yellow ray florets. The outer edge of each ray floret has a fringed appearance consisting of 4 acute lobes. Each flower is subtended by several triangular green bracts; the inner bracts are somewhat smaller and often brownish green. The blooming period occurs during early summer and lasts about a month. There is no noticeable scent to the flowers. The dark achenes are rather flat and oblong, and have 2 small barbs near the top. The root system is fibrous. This plant often forms colonies by reseeding itself.
