Often found growing among moist rock outcrops, crevices, cliffs, and gravelly slopes, alum root thrives in difficult locations. It is generally associated with shady, moist locations, but it can grow in full to part sun with adequate moisture and good drainage. Alum root is perfect for a shady rock garden. This evergreen perennial wildflower in the saxifrage family can be highly variable, but most often has lobed, green leaves and an erect spike of dainty flower clusters up to 3′ tall. The small flowers can be pink, white, or greenish in color. The flowers are attractive to native bees, butterflies, and hummingbirds.
Alum root (Heuchera micrantha) seed packets contain approximately 750 seeds.
