Amsonia hubrichtii
Arkansas Amsonia or Hubricht's Blue Star

Amsonia hubrichtii, native to the states of Arkansas and Oklahoma is a wonderful low maintenance plant that provides ornamental interest throughout the growing season. Loosely upright stems appear in spring, and slowly bend into a cascading form by fall. Arkansas Amsonia flowers in May, with clusters of pale, ice blue flowers that shade slightly towards turquoise.

star-shaped flowers in May.

Amsonia hubrichtii grows about 24-30" tall and is hardy in zones 5-9, and perhaps in zone 4 with protection. Give this plant plenty of space in the garden, 21/2-3'. While single specimens are lovely on their own, mass plantings are also very effective, especially in the fall. Arkansas Amsonia has very few to no problems with pests.

Arkansas Amsonia may be seen to the right of the main entrance to the Talcott Greenhouse, as well as in the 1904 Garden.

After the flowers fade, the narrow, thread-like foliage of Amsonia hubrichtii adds a fine textural effect in the garden. And what a sight this plant is in October, when the foliage turns a brilliant yellow, lighting up the garden for several weeks. Arkansas Amsonia is a real eye-catcher in fall, and many greenhouse and garden visitors request the name of this plant at that time.
