It is a perennial plant, first discovered in 1788. It is found in wooded areas and on riverbanks. It blooms in May and June. Each flower has five pale blue flower petals and blooms in clusters on two to three-foot stems. The upright stems with narrow leaves are attractive all summer and turn into beautiful butterscotch-yellow in autumn. The plants grow in full sun to light shade. Narrow, willow‑shaped, dull green foliage may turn into an attractive yellow in autumn.
