Amsonia hubrichtii, commonly known as Hubricht’s bluestar, is a perennial herb native to the Ouachita Mountains and adjacent areas in Oklahoma and Arkansas, where it thrives in open woodlands and prairies. This species, a member of the dogbane family, was first described in 1943. It typically grows to a height of 2-3 feet (0.6-0.9 meters) and spreads 2-3 feet (0.6-0.9 meters) wide. The plant features feathery, fine-textured foliage that turns a stunning golden-yellow in the fall. In late spring to early summer, pale blue, star-shaped flowers bloom in clusters, adding a soft, yet showy aspect to garden settings.

Hubricht’s bluestar is valued for its season-long interest, starting with blue flowers in the spring, followed by fine-textured green foliage in the summer, and culminating with bright yellow fall color. It is commonly used in borders, native plant gardens, and as a mass planting for a dramatic effect. This plant is adaptable to various soil types, provided they have medium drainage, and it is relatively drought-tolerant once established. It prefers full sun to part shade and requires medium amounts of water. While generally pest and disease-free, it can be susceptible to rust in overly moist conditions. Hubricht’s bluestar is not known for being invasive and is considered a low-maintenance addition to the garden.CC BY-SA 4.0
