Hairy alumroot
Heuchera villosa
A native southeastern US heuchera with large rounded velvety lobed leaves (the namesake 'hairy' is the fine pubescence on the foliage) + airy panicles of small white-to-pink flowers on tall slender stems in late summer. Among the most heat- and humidity-tolerant heucheras - solves the southern-shade heuchera-rot problem that plagues most Heuchera americana × sanguinea garden hybrids. The genetic parent of many heat-tolerant Heuchera cultivars.
