Description edit
A. hubrechtii grows 60–90 centimetres (2–3 ft) high with upright stems that form bushy clumps. Leaves are very narrow, numerous, and alternate, giving the plant a feathery appearance. In the spring the leaves are bright green, and they turn gold in the fall. The flowers, borne in clusters at the end of each stem in the spring, are a powdery blue color and 1.3 centimetres (.5 in) across.[8] The flowers have 5 petals and fade to white with warmer temperatures.[4]
Distribution and habitat edit
The plant is known from a limited number of populations in Oklahoma and Arkansas, primarily within the Ouachita Mountains Natural Division. In Oklahoma, it is considered an endangered species.[7] It grows well in poor soils and full to partial sun.[4]
