Amsonia hubrichtii, is an uncommon perennial that is native to the drier parts of the Ouachita Mountains in central Arkansas.
Powdery blue, petite, star-like flowers appear in late spring atop strong and sturdy stems. It's an an erect, clump-forming plant with feathery green summer foliage and ravishing autumn colour.
There are very few perennials that supply such a long season of interest. Amsonia grown in full sun will have increased flower production and more compact habits.
Plants that become loose or open, especially when grown in too much shade, can be cut back to 10 inches after flowering to encourage shorter, sturdier stems.
The genus is quite slow growing and can be left untouched for years. The foliage and stems contain a milky sap, which seems to make the plant unappealing to foraging animals.
Moist, well drained
Full sun, partial shade
