Liatris microcephala
50 potted in late May, 2016.
"Defying summer extremes of heat, humidity and drought, Liatris microcephala is an easy care herbaceous perennial that thrives in full sun and poor soil. Growing from a woody corm, it produces a tuft of fine textured, grass-like foliage in spring. Then in late summer multiple 2-2½’ erect leafy stems, encircled by numerous ¾” rose-purple flowers, grace its tufted mound. Plants require lean, well drained soil, especially in winter. Small-headed gayfeather makes a vibrant vertical accent in a sunny border." —Mt. Cuba Center
