This very useful native from Arkansas, commonly known as Threadleaf Bluestar, has fine textured linear leaves which clothe the 3′ stems, terminating in clusters of soft blue flowers which are attractive to butterflies in late spring. After the blooms fade, Amsonia foliage remains attractive right into autumn, when cooler temperatures cause the foliage to turn shades of lemon and amber. Amsonia is tolerant of a range of soil conditions, is slow to clump up at first, but very long lived, and is deer resistant.
