Citronelle Coralbells were discovered in 2002 in Hantay, France, as a sport of Caramel Coralbells. This cultivar is reported to have better tolerance of hot, humid summers than other varieties, although this is more relevant when planting in sites south of Zone 5.
The Heuchera genus includes over 30 recognized species, all native to much of North America. They are found on a wide variety of sites, from rocky outcroppings to wooded meadows, with a variety of different growth habits. Although useful for many landscape applications, Coralbells were not widely used until the 1980s. Today, there are a plethora of cultivars available with different foliage colors, flowers, and growth forms. At Johnson’s Nursery, we try to limit our inventory to those varieties we know are successful for our Southeastern Wisconsin soils and climate.
Coralbells are also known as Alumroot, a name derived from their medicinal properties as a pain reliever and anti-inflammatory. The genus name Heuchera is a reference to the German botanist and physician Johann Heinrich von Heucher.
