Amsonia hubrichtii has the common name Bluestar or Threadleaf Bluestar. It is a hardy, long-lived perennial native to Arkansas, Oklahoma and Missouri.
This Amsonia has lovely, feathery foliage that adds a unique, billowy texture to the garden. It blooms in spring with light blue, star-like flowers – but this plant really shines in the fall with brilliant golden-yellow foliage.
Amsonia hubrichtii is easy to grow in average, well-drained soil . With time it can grow quite large, 3-4 feet tall and wide with a shrub-like appearance. This perennial starts slow and may need a couple years to fill out but once established it is hardy, dependable and rarely needs division. A polite grower, it does not spread by rhizomes and is not known to aggressively self-seed. Amsonia hubrichtii is deer and rabbit resistant and has no serious pests or diseases.
The flowering and fall color is best in full sun, but it will tolerate some shade. If grown in too much shade or very rich soil, its habit will be open and floppy. Cutting it back about 6 inches after blooming will help prevent flopping.
