Amsonia hubrichtii (Information provided by the University of Arkansas)

This Arkansas wildflower is a welcome addition to the lineup of Arkansas Select plants. This species of Amsonia was first recognized as a distinct species in 1942 by Missouri Botanic Garden botanist Robert Woodson using material provided him by Leslie Hubricht. The material he collected was found in Garland County. Since then, Arkansas Blue Star has been found throughout the Ouachita region and into adjacent areas of Oklahoma. Of all of the blue star species, this Arkansas native is considered most ornamental. It has blue, star-like clusters of flowers in the spring and masses of soft green, ferny foliage in the summer. In the fall, the foliage turns a beautiful yellow, marking the plants’ most ornamental period.

Height: 30 to 36 inches. 
Spread: 36 inches or more but from a defined crown. 
Hardiness: Hardy statewide and as far north as zone 5. 
Planting Season: Plant anytime available from the nursery. 
Cultural Comments: This plant is native to dry, rocky outcrops in full sun or part shade. Plants should be watered until well established, but afterwards, will fend for themselves. In the perennial border, give the plant room to achieve its full stature. Don’t crowd it.
