Quick Overview:

This bluestar (sometimes commonly called Arkansas amsonia or Hubricht’s amsonia) is an uncommon perennial that is native to the Ouachita Mountains in central Arkansas. It is very similar in appearance to the Missouri native Amsonia ciliata, except the leaves of A. hubrichtii are more narrow and thread-like and the emerging foliage lacks conspicuous hairiness. An erect, clump-forming plant that is primarily grown in cultivation for its blue spring flowers, feathery green summer foliage and golden fall color. Powdery blue, 1/2″ star-like flowers appear in terminal clusters in late spring atop stems rising to 3′ tall. Feathery, soft-textured, needle-like, alternate leaves are bright green in spring and summer, but turn bright gold in autumn. From a distance plants have an almost lily-like appearance.  (Courtesy of Missouri Botanical Gardens Plant Finder)


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. Stems tend to open up and flop in too much shade, however. Consider cutting back the stems by about 6″ after flowering to help keep stems upright and to shape plants into a nice foliage mound.  (Courtesy of Missouri Botanical Gardens Plant Finder)
