This herbaceous perennial plant is ½–1½' tall, branching occasionally. The leafy stems have a tendency to lean to one side or sprawl across the ground. The stems are light green to reddish green, glabrous to hairy, and often somewhat angular. The alternate compound leaves are simple odd-pinnate and up to 8" long, consisting of about 5-15 leaflets. The petioles and rachises of these compound leaves are light green to reddish green and glabrous to hairy; they are grooved above and convex below. The leaflets are ¾-1¼" long and about one-third as much across; they are elliptic to broadly elliptic-oblong, smooth (entire) along their margins, medium green, glabrous (or nearly so), and sessile (or nearly so). The upper stems terminate in rather loose panicles of floppy or nodding flowers spanning 1½-3" across. Some panicles are also produced from the axils of upper leaves on long peduncles up to 6" long. The pedicels are up to 1" long. Both the peduncles and pedicels of these panicles are light green to reddish green and glabrous to hairy. The campanulate (bell-shaped) flowers are up to 15 mm. (2/3") across. Each flower has 5 rounded petals that are light blue-violet, a short-tubular calyx with 5 triangular teeth, 5 stamens with white anthers, and a pistil with a slender white style that become tripartite toward its tip. The calyx is light green to reddish purple and glabrous to hairy. There are fine veins that run along the length of the petals. The stamens are the same length as, or shorter than, the petals of the flowers. The blooming period usually occurs during the late spring, lasting about 2-3 weeks. Afterwards, the flowers are replaced by 3-celled seed capsules; these capsules are about 6 mm. (¼") in length and ovoid in shape; they are few-seeded. The root system consists of a short vertical crown with abundant fibrous roots. This plant spreads by reseeding itself. Cultivation
