Mesic to moist grassy bluffs, streambanks, meadows, rocky river banks, roadsides and forest margins, gravelly prairies and thickets in the lowland and montane zones.[3][2]


There are many important species in the Heuchera genus, both for medicine and tanning, because of their generally extremely astringent roots.

Heuchera chlorantha is a nectar source for many species of native bumblebees.[5]
