We purchased this plant many years ago from Plant Delights Nursery in Raleigh, NC and it turned out to be one of the most asked about perennials in our display beds. Clumps of fine textured foliage hug the ground at 4-6" with a spread of 24". Sky-blue, star-like flowers emerge in spring and will continue for weeks. The golden fall foliage just enhances the desire for this extraordinary plant. They prefer full sun for best color and soils with good drainage.
