This is a native perennial plant that branches sparingly, and is up to 3½' tall. The alternate leaves are bipinnately or ternately compound, and tend to be aggregated toward the base of the plant. The basal leaves are up to 12" long and 6" across, while smaller leaves are sparsely distributed along the middle and upper portions of the stems. Sometimes there are minute stiff hairs at the base of the petioles where the compound leaves meet the stem. The leaflets have large blunt teeth, and often occur in pairs or triplets, with the terminal leaflets achieving the largest size. Each leaflet is up to 1" long and ½" across, lanceolate or ovate, and has wedge-shaped lower margins. The overall appearance of the leaves resembles Italian Parsley. Rounded compound umbels of light yellow flowers occur at the ends of the central stem and major side stems. Each umbel is about 3" across, and is composed of 12-20 umbellets. Each umbellet consists of a similar number of tiny flowers, each one with 5 petals. There is no noticeable floral scent. The blooming period occurs during the late spring or early summer, and lasts about a month. The root system consists of a central taproot.
