Summary
Heuchera, also known as coral bells or alumroot, are a favorite of gardeners everywhere. Their popularity is proven by the huge array of cultivars available today. The incredible amount of excitement surrounding Heuchera has led to an excessive amount of choices as well as the occasional release of inferior or redundant plants before adequate trialing. For these reasons, Mt. Cuba Center set out to evaluate 83 different cultivars derived from two species native to the eastern United States. Those species, H. americana and H. villosa, have lent hardiness, vigor, and important color components to modern hybrids. After three years of evaluating plant habit, vigor, bloom time, flower color, sun tolerance, pest and disease resistance, and overall adaptability, ten cultivars stood out as top performers. These prominent performers are ‘Citronelle’, ‘Bronze Wave’, ‘Cajun Fire’, ‘Color Dream’, ‘Steel City’, ‘Caramel’, ‘Apple Crisp’, ‘Frosted Violet’, ‘Southern Comfort’, and ‘Spellbound’.
