Culture

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. Foliage is essentially evergreen in warm winter climates, but the amount of retained foliage color in cold winter climates 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.

Noteworthy Characteristics

This foamy bells cultivar is an intergeneric hybrid between a variety of Heuchera and a variety of Tiarella. It is a clump-forming perennial which typically produces a compact, basal mound (to 6" tall) of rounded, lobed, long-petioled, bronze leaves with a silver metallic overlay. Tiny, white, bell-shaped flowers borne in open, airy panicles appear in late spring to mid summer on slender, wiry, dark stems rising well above the foliage mound (typically to 18" tall). Flowers are larger and bloom is more floriferous than that of most Heucheras. A Blooms of Bressingham introduction.

Problems

No serious insect or disease problems. Frost heaving of roots may occur when winter temperatures fluctuate widely.

Garden Uses

Mass as a ground cover or group. Rock gardens, borders and open woodland gardens. Effective as an edger along paths or walkways.
