Uniquely colored foliage on a large, bold, vigorous plant. 'Caramel' is partly derived from the Southeast native H. villosa and as a result thrives on summer heat and humidity. Once established, it will also grow in dry shade. Rarely flowers. All its energy goes into lots of superb foliage.
Best grown in organically rich, humusy, medium moisture, well-drained soils in full sun to part shade. Performs well in full sun in the north, but generally prefers some shade (particularly in the heat of the afternoon) in the south. If grown in full sun, consistent moisture is important. Scorch and general foliage decline tend to occur if soils are allowed to dry out. Notwithstanding the foregoing, 'Caramel' is considered to be more tolerant of hot and humid summers than most other heucheras, in large part because it reportedly has H. villosa (SE US native) in its parentage. Remove stems of faded flowers to encourage additional bloom. Some gardeners prefer to remove flower stems before flowering if plants are being grown as ground covers for their foliage texture and color. Foliage is essentially evergreen in warm winter climates. In cold winter climates such as St. Louis, the amount of retained foliage color depends in large part upon the severity of the temperatures. A winter mulch applied after the ground freezes will help prevent root heaving. Divide clumps in spring every 3-4 years.
