Heuchera

Heuchera ( or ) is a genus of largely evergreen perennial plants in the family Saxifragaceae. All species are native to North America except for Heuchera sichotensis, native to the Russian Far East. Common names include alumroot and coral bells.

==Description== Heuchera have palmately lobed leaves on long petioles, and a thick, woody rootstock. The genus was named after Johann Heinrich von Heucher (1677–1746), an 18th-century German physician, and Professor at Wittenberg University. 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.
