DescriptionThis is a native perennial wildflower about 1½5' tall that regularly branches. The erect to ascending stems are light green to dull reddish brown, terete, and densely covered with long glandular hairs. The blades of the alternate or opposite leaves are up to 10" long and half as much across, becoming gradually smaller as they ascend the stems. They have long hairy petioles. The lower to middle leaf blades are pinnately lobed and somewhat dentate or undulate along their margins; there are usually 3-7 major lobes with pointed tips. The upper leaf blades often lack lobes; they are usually deltoid-ovate or a similar shape. The upper surface of each leaf blade is dull medium green; it is either hairless or slightly hairy. Small clusters of flowerheads develop from the upper stems and the axils of upper leaves. Each flowerhead is about ½" across; it has several disk florets in the center and 5-7 ray florets along its edges. The small disk florets have cream-colored tubular corollas with 5 lobes; their reproductive organs form columnar structures that are golden yellow. The white ray florets terminate into 3 short lobes; sometimes the petal-like extensions of the ray florets are absent. Only the ray florets are fertile. At the base of each flowerhead, there 5 outer phyllaries (floral scales) that are light green and pubescent; these outer phyllaries are lanceolate-ovate and become recurved when the flowerheads bloom. Sometimes, there are 1-2 small leafy bracts underneath each flowerhead; they are linear-lanceolate in shape. The blooming period occurs from mid-summer into the fall and lasts about 2 months; only a few flowerheads are in bloom at the same time. Somewhat later, the flowerheads turn brown and each ray floret is replaced by an obovoid achene that is prominently 3-angled; there is no tuft of hairs at its apex. The root system is fibrous.
