The coralbells or alumroots, Heuchera species, are a genus of 37 species in the saxifrage family Saxifragaceae. They are endemic to (native to and only found in) North America, at least one species native to every state but Florida. Some have really small ranges, within a single state or part of a state (see USDA map link). Mostly the wild ones are called alumroots, while the larger species, several of which have been domesticated as garden plants, are called coralbells.
