Amsonia tabernaemontana
A long-lived, clump-forming perennial that develops upright, leafy stems through spring and early summer. Pale blue, star-shaped flowers appear early in the season, after which the plant continues to fill out, forming a dense, willowy mass of foliage that serves as a steady backdrop to later-flowering plants.
