Amsonia hubrichtii
Arkansas bluestar is native to eastern Oklahoma and Arkansas, but does well throughout
the state. It is tolerant of moist soils and is quite drought tolerant once established.
Flowers are sky blue, star shaped and develop in clusters at the end of each branch
in early spring. Leaves are needle-like on upright stems that sway in the breeze providing
a soft, wispy appearance; foliage is bright green in summer and then in fall, seemingly
overnight, it explodes to a golden yellow. Amsonia grows to 3 feet high. Plant in
masses for best effect. Can be used in mixed borders, meadows, native gardens, and
open woods.
Exposure: Sun, part shade
Soil: Moist, well-drained
Hardiness: USDA Zone 4-9
