Description

This native perennial wildflower is ½–2' tall. At the base of each plant, there is a small rosette of basal leaves spanning about 6-8" across. The blades of the basal leaves are typically 2-3" long and 2" across; they are cordate-orbicular to cordate-oval in shape, crenate-dentate along their margins, and hairless. The slender petioles of the basal leaves are as long as the blades. A flowering stalk develops from the center of each rosette. Along this stalk, there are usually 2-3 alternate leaves. The alternate leaves are smaller in size than the basal leaves and pinnatifid in shape. Both the alternate leaves and the stalk are hairless during the blooming period and thereafter. The stalk terminates in a flat-headed panicle (or corymb) of flowerheads. The branches of this panicle are slender and hairless. Each daisy-like flowerhead is ½–¾" across; in the center there are numerous golden yellow disk florets, which are surrounded by 6-16 yellow ray florets. Both the disk and ray florets are fertile. Surrounding the base of the flowerhead, there are numerous linear green bracts in a single series. The blooming period occurs from mid- to late spring and lasts about 3 weeks. Each floret is replaced by a bullet-shaped achene with a small tuft of white hairs. The achenes are distributed by the wind. The short rootstock has spreading fibrous roots and it produces rhizomes (or stolons). Vegetative colonies of plants are often produced in favorable habitats.
