Coral bells<\/strong> (Heuchera spp<\/em>) or alumroot are Tennessee natives. They represent an almost limitless choice of foliage colors, sizes, and forms (USDA hardiness soils 4-9). The biggest chore a gardener has is selecting what cultivar(s) to plant. There is over one hundred to choose that range from grow 8 to 12 inches in height and 1 to 2 feet spread. The coral bell color palette is a landscape designer\u2019s dream plant. Should I mention that some varieties bloom exceptionally well.<\/p>\n\n\n\n

Foliage color choices range from lemon yellow to green to nearly black, that may be glossy, matted, or marbled. Spring \/ summer flowers stand above the foliage. Flower stalks may reach 2 to 3 feet in height. Coral bells are suitable in most any landscape situation from mixed borders, mass plantings, and containers.<\/p>\n\n\n\n

In the south, heuchera plants are best in an open woodland setting, but can tolerate a fair amount of morning sunlight. Plant in a humus-rich, moist, well-drained soil. In the north, coral bells grow well in full-day sunlight. In southern gardens, coral bell hybrids with a Heuchera villosa<\/em> bloodline are longer-lived where heat and humidity are major issues.<\/p>\n\n\n\n

Additional choice: Plant breeders have successfully crossed heuchera with its botanical cousin Tiarella (\u201cfoam flower\u201d) to produce a more tougher shade plants (written as \u201cx Heucherella<\/em>\u201d).<\/p>\n\n\n\n

Northern gardeners have found that a layer of\u00a0winter mulch\u00a0helps protect the plant crowns in zones 4 and 5. Heuchera<\/em> and x Heucherella<\/em> exhibit\u00a0good drought tolerance. During the dry portion of the growing season, supply an additional 1- inch of water weekly. Avoid planting heucheras in wet soggy soils.<\/p>\n\n\n\n

Heuchera and x Heucherella clumps should be dug up and divided every 3-4 years in early spring. Heuchera<\/em> and x Heucherella<\/em> are generally\u00a0left alone by\u00a0deer\u00a0and\u00a0rabbits. However, when populations are exceptionally high, these critters will eat any plant, including coralbells and their relatives.<\/p>\n\n\n\n

In general, heuchera and x Heucherella are\u00a0not troubled by disease and insect problems. Foliar nematodes\u00a0may disfigure leaves in late summer. There is no suitable control measures against nematodes. Black vine weevil is reported to be a problem in the Northwestern U.S.<\/p>\n\n\n\n

In southern gardens, some cultivars may be damaged by summer dieback identified as\u00a0 Sclerotinia<\/em>\u00a0 fungus. Suggestion: gardeners should talk with one another to select cultivars that perform best in their region.\u00a0Good air circulation\u00a0is the best preventative to avoid diseases.<\/p>\n\n\n\n
