Heuchera 'Crimson Curls' (Crimson Curls Coral Bells) - A clump-forming herbaceous perennial that forms a basal mound to around 9 inches tall by about 18 inches wide. The 2 to 4 inch wide leaves emerge in spring a dark burgundy red with purple underneath and are distinctively curly. Leaves fade to a duller gray green in summer. In late spring to early summer appear the small white bell-shaped flowers on slender stems that rise above the foliage to 12 to 18 inches tall (well above foliage). Remove stems of faded flowers to encourage additional bloom in fall. Performs well in full sun in cooler gardens but needs some shade (particularly afternoon) in warmer spots. Plant in well-drained soil and irrigate regularly. Foliage will be scorched and plants will decline if getting too much sun or not enough water. This plant is evergreen in our garden but can be grown in much cooler climates as a hardy perennial. This plant was introduced by Ray Brown of Plant World Botanic Gardens in Devon, England and was released in the United States by PlantHaven of Santa Barbara, California. It was selected as a seedling in 1996 from a planting bed of several named and unnamed Heuchera cultivars and hybrids that had been planted in 1993. The planting was to allow open pollination to occur so selections could be made of seedlings exhibiting new leaf variants. It is thought that 'Crimson Curls' may have derived its foliage color partially from 'Palace Purple' and the crispy metallic leaf texture from the species H. micrantha or possibly H. americana. However, the exact parents are unknown. It received US Plant Patent PP13,729, which has since expired. In their book "Heuchera and Heucherellas: Coral Bells and Foamy Bells" Timber Press 2005 authors Dan Heims and Grahame Ware note that Linnaeus named Heuchera for Johann Heinrich von Heucher, professor of medicine and Botany at Wittenberg University. They further note that the name Heuchera should be pronounced following the person's name it commemorates so the proper pronunciation is HOY-ker-uh.
The information displayed on this page is based on research conducted about this plant in our library and from reliable online sources. We also consider observations that we have made of it growing in the nursery's garden and in other gardens, as well how it has performed in our crops out in the nursery field. We will incorporate comments that we receive from others as well, and welcome hear from anyone who may have additional information, particularly if they have knowledge of cultural information we do not mention that would aid others in growing Heuchera 'Crimson Curls'.
