Amsonia hubrichtii
Threadleaf Blue Star, Arkansas Blue Star
Threadleaf Blue Star is an upright clumping perennial with soft thread-like foliage that is bright green until fall when it turns showy gold. Clusters of small powdery blue or white star-shaped flowers bloom at the tips of the stem in spring. Best fall colors are in full sun, but flowers last longer with afternoon shade in hot climates.
Amsonia hubrichtii is a native plant that acts as a host for Swallowtail Butterfly larva, and attracts other bees and butterflies. The sap does not taste well to many insects or herbivores, so it makes for a good barrier for more susceptible plants.
