This short and sweet dwarf variety is fantastic for use in perennial borders, rain gardens and mixed containers with its shorter stature and upright habit. Attractive, dome-shaped clusters of tiny, rosy-purple blooms are a favorite of butterflies and gardeners alike, lasting from mid-summer through fall before turning into tufts of fuzzy seed heads with late autumn interest. A clump-forming perennial with whorls of coarse green leaves on sturdy stems.
