Heuchera - the alumroot or coral bells - is a genus of evergreen herbaceous in the family Saxifragaceae, all native to North America. It is a perennial growing 20-30 cm high (8-12 in) with rosettes of palmately lobed leaves in shades of green, pink and bronze, often variegated or textured and white, green, pink or red flowers in spring. There are approximately 37 species, but horticulturists have developed many hybrids with an extensive array of sizes, shapes, and flower colors, and foliage types. The majority of Heuchera sold for gardens are hybrids of H. americana, such as 'Green Spice’, or crosses of Heuchera with Tiarella treated under the name × Heucherella.
