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 prefers some shade (particularly in the heat of the afternoon) in the south. In the St. Louis area, best foliage color may occur in sunny spots with part afternoon shade. Scorch and general foliage decline usually occur if soils are allowed to dry out. If grown in full sun, consistent moisture is particularly important. Remove stems of faded flowers to encourage additional bloom. On the other hand, some gardeners prefer to remove flower stems before flowering if plants are being grown for their foliage texture and color. Foliage is essentially evergreen in warm winter climates, but the amount of retained foliage color in cold winter climates such as St. Louis depends in large part upon the severity of the temperatures. In cold winter climates, a winter mulch applied after the ground freezes will help prevent root heaving. Divide clumps in spring every 3-4 years.
‘Amber Waves’ is a vigorous, clump-forming coral bells cultivar that is best noted for its ruffled, amber leaves. It is the result of a tissue culture of a petiole off a gold leaf found on a Heuchera ‘Whirlwind’. This is a clump-forming perennial which features large, ruffled, amber gold leaves and light rose-pink flowers. Rounded, lobed, long-petioled leaves form a basal mound (to 8” tall) which may spread to 17” wide. Best foliage color occurs in spring. Tiny, very light pink flowers borne in open, airy panicles appear in late spring to early summer on slender, wiry stems rising above the foliage mound (typically to 12” tall). U. S. Plant Patent PP13,348 was issued on December 10, 2002.
No serious insect or disease problems. Frost heaving of roots may occur when winter temperatures fluctuate widely.
Mass as a ground cover or group. Rock gardens, borders and open woodland gardens. Effective as an edger along paths or walkways.
