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 and to tidy plantings so that the attractive foliage can be fully appreciated. 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
× Heucherella, commonly called foamy bells, is an intergeneric hybrid between Heuchera and Tiarella. It is generally more compact and delicate in appearance than its Heuchera parent. It is a clump-forming perennial which typically produces a compact, basal mound of rounded to lobed leaves usually with distinctive veining. Foliage clump typically rises 5-8" tall. Foliage will usually retain some color in cold winter climates such as the St. Louis area. Tiny star-shaped flowers appear in airy to dense panicles atop stems rising well above the foliage clump (typically to 15-20" tall) in late spring to mid-summer.
‘Dayglow Pink’ is noted for its mauve-pink flowers and for its deeply lobed (maple-like) green leaves with chocolate brown veining. U. S. Plant Patent PP12,164 issued October 23, 2001.
Problems
No serious insect or disease problems. Frost heaving of roots may occur when winter temperatures fluctuate widely.
Uses
Though the flowers are attractive, heucherellas are usually grown for their showy foliage. Mass as a ground cover or group. Rock gardens, borders and open woodland gardens. Effective as an edger along paths or walkways. Showy foliage for patio and deck areas. Shade gardens. Trailers spill nicely out of hanging baskets, window boxes or other large containers.
