Amsonia (am-soh-nee-uh), Blue Stars; Dogbane Family (Apocynaceae). Amsonia have small funnel-shaped flowers. Easily grown in average, medium, well-drained soil in full sun to part shade. Best fall foliage color usually occurs in full sun. Flowers generally last longer if given some afternoon shade in hot sun areas, however, stems may open up and flop with too much shade, however. Consider cutting back the stems by about 6 inches after flowering to help keep stems upright and to shape plants into a nice foliage mound.
