Arkansas Blue-star. I suppose that this is one of the few perennials which is grown more for its fall color rather than for its flowers. But even so, its stems are topped in the spring by soft blue terminal panicles of star-like flowers. Even if it did not flower, its soft textured foliage gives great contrast in the perennial border, and then as Allan Armitage says, "the golden yellow spectacle in the fall is second to none among herbaceous plants." To add to its many attributes, it is a native as well.
