(Syn. Machaeranthera bigelovii)
“Purple Tansy Aster”
Big & showy late Summer & Fall color is provided by this native Aster from the Southwestern U.S. Forming a 3’ x 3’ mound, it explodes into a mass of large (1.5”), multi-rayed, purple blooms in September & October. Not fussy about soil & drought tolerant, though it blooms better with some water.
