Plants range in size from dwarf alpine plants with flower spikes rising to only 5” tall to much larger woodland plants with flower spikes towering to 36” tall. Plants grow in a variety of different habitats including woodland areas, Appalachian seeps, prairies, rocky cliffs and alpine slopes. Heuchera, commonly called coral bells or alumroot, is a genus consisting of about 55 species of evergreen to semi-evergreen herbaceous perennials which are all native to North America. Species plants may be grown from seed, but hybrids are usually divided in the garden. A winter compost mulch applied after the ground freezes will help prevent root heaving. Louis, the amount of retained foliage color in winter depends in large part upon the severity of the temperatures. Foliage is essentially evergreen in warm winter climates. Remove stems of faded flowers to encourage additional bloom. On the other hand, some hybrids perform well in shady locations, particularly if H. Scorch and general foliage decline may occur if soils are allowed to dry out.
TWIG SCIENCE FULL
If grown in full sun, consistent moisture is very important. Some hybrids will perform well in full sun, particularly in northern climates, but generally prefer some shade in the heat of the afternoon in southern locations. Unfortunately, the parentage of many hybrids in commerce today is unknown. Parentage determines the best culture including optimum sun exposure.
Heucheras are best grown in organically rich, humusy, medium moisture, well-drained soils in part shade.
