Amsonia hubrichtii

Blue Star

Amsonia hubrichtii, or Bluestar is an uncommon perennial that is native to the Ouachita Mountains in central Arkansas. An erect, clump-forming plant that is primarily grown for its blue spring flowers, feathery green summer foliage and golden fall color. Powdery blue, star-like flowers appear in late spring. Feathery, soft-textured, needle-like leaves are bright green in spring and summer, but turn bright gold in autumn. This species was named after Leslie Hubricht who first discovered it growing in the wild in the early 1940s.

Blue Star Growing and Maintenance Tips:

Easily grown in average, medium, well-drained soil in full sun to part shade. Best fall foliage color usually occurs in full sun, but flowers generally last longer if given some afternoon shade in hot sun areas. Cut back the stems after flowering to help keep stems upright and maintain a nice shape.
