Henchera villosa var. macrorrhiza "Autumn Bride" (Hairy Alum Root)
Here is a Heuchera for the late summer garden. This one grows from two to two and a half feet (with flowering stems), tiny creamy white blooms, and large bright lime green hairy foliage. The blooms last for a long time, sometimes into October. "Autumn Bride" reseeds and will colonize, if you're lucky. "Autumn Bride" requires full sun to part shade (particularly in the south) and rich, humusy soil with medium moisture. It has good drought tolerance once established, but if in full sun, consistent moisture is advised. Mulch the roots in winter to help prevent heave and thaw and divide every three or four years in spring. (Photo courtesy of Missouri Botanical Garden and used with permission). Zones 3-8.
