A little-known perennial native to the southern USA, and ideally suited to the border or wildflower meadow garden. Plants are long-lived, forming an arching clump of soft, feathery green leaves. Pale-blue starry flowers appear in late spring, and these are nice for cutting. Excellent bright golden fall colour. Makes an interesting specimen plant, surrounded by something low and spreading. Clumps are easily divided in early spring, before the new growth starts. Deserves to be better known and grown. Tolerant of hot, humid summer regions.
