Arkansas blue star’s delicate, willow-like foliage is topped with pale blue star-shaped flowers in spring. The light green foliage looks good all summer, turns a beautiful golden-yellow in fall, and can stand through most of the winter, adding interest especially when mixed with grasses and other attractive seedheads. It grows to almost 3 feet tall and wide. This U.S. native offers a long season of interest, with its blue spring flowers, attractive feathery leaves, and golden yellow fall color. This plant really shines once established.
