I first saw the handiwork of French breeder Thierry Delabroye on a 2004 trip to Holland. I returned home with a plant of Heuchera 'Caramel' and planted it beside other coral bells that were on trial. By the end of the summer (more than 100 days over 86 degrees F), most of the coral bells were dead. However, Heuchera 'Caramel' loved the weather. The reason is the use of the heat-loving Heuchera villosa in the breeding line. The 1' tall x 2' wide hairy clumps emerge with butterscotch foliage which changes to peachy-orange as the season progresses. These sun-tolerant plants are topped in summer with tall spikes of small white flowers.
