Native to Arkansas, Amsonia hubrichtii (Narrowleaf Bluestar) is an erect, clump-forming perennial which provides 3 seasons of interest with its starry blue flowers in spring, its bright green summer foliage, and its charming fall color. This Blue Star features loose terminal clusters, up to 5 in. long (12 cm), of delicate, pale blue, star-shaped flowers borne on upright stems in late spring – early summer. They rise above the graceful foliage of soft-textured, needle-like, bright green leaves that pleasantly colors up to bright golden-yellow in fall. It makes an excellent backdrop for fall-blooming perennials such as sedums and garden mums.
