Heuchera
Also called Alum Roots
Heuchera, or alumroot, is a genus of mostly evergreen perennials grown mainly for their colourful, ruffled foliage and airy spring flower spikes. Most garden plants are hybrids, so care varies, but they generally need well-drained soil and some shelter from strong afternoon sun.
Heuchera ( HEW-kih-rə or HOY-kih-rə) 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.
The majority of Heuchera sold for gardens are hybrids of H. americana, such as 'Green Spice'.
The original 'Purple Palace' discovered in a palace in England is believed to be a H. micrantha × H. villosa hybrid, which was then crossed with H. americana. Another group of hybrids are crosses of Heuchera with Tiarella treated under the name × Heucherella. Gardeners and horticulturists have developed a multitude of hybrids between various Heuchera species. There is an extensive array of blossom sizes, shapes, and colors, foliage types, and geographic tolerances. They are valued as foliage plants, producing rosettes of leaves in shades of green, pink and bronze, often variegated or textured; with long thyrses of white, green, pink or red flowers in spring.
Alumroot species grow in varied habitats, so some species look quite different from one another, and have varying preferences regarding temperature, soil, and other natural factors. H. maxima is found on the Channel Islands of California, where it grows on rocky, windy, saline-washed ocean shores, and H. sanguinea, called coral bells because of its cerise flowers, can be found in the warm, dry canyons of Mexico and adjacent New Mexico and Arizona. In the Mid-Atlantic region of the United States, the plants grow best in shade.
Native American peoples used some Heuchera species medicinally. The Tlingit used H. glabra as an herbal remedy for inflammation of the testicles caused by syphilis. To the Navajo, H. novamexicana was a panacea and a pain reliever. The roots of H. cylindrica had a variety of medicinal uses among the Blackfoot, Flathead, Kutenai, Okanagan, Colville, and Shuswap.
