American Alumroot
Heuchera americanaAlso known as Rock Geranium, Coral Bells
American alumroot forms tidy basal mounds of scalloped, heart-shaped foliage across rocky hillsides and open deciduous woodlands. In late spring, slender wiry stalks elevate loose airy clusters of tiny bell-shaped, cream-to-greenish blooms that attract small native bees and syrphid flies. Valued for its robust cold tolerance and intricate leaf veining, the wild species serves as a foundational parent for dozens of popular ornamental coral bell cultivars.
