All species are native to North America except for Heuchera sichotensis, native to the Russian Far East. Most are evergreen perennial plants. Heuchera have palmately lobed leaves on long petioles, and a thick, woody rootstock. There are approximately 37 species, but the taxonomy of the genus is difficult because the species often intergrade with one another, hybridization is common, and the flowers change markedly in proportion as they develop. Several alumroots and their crosses are used as ornamental plants.
