American alumroot
Heuchera americanaAlso known as Rock Geranium, Alum Root
American alumroot forms dense mounds of lobed, marbled foliage that often shifts to rich copper and purple hues in cooler weather. Slender flowering stalks emerge in late spring, bearing subtle bell-shaped green to cream blossoms that attract native bees and pollinators. Rooted firmly in rocky slopes and shaded woodlands, this resilient perennial stabilizes forest soils while offering persistent ground cover year-round.
