'Harmonic Convergence' (PP11,111) has boldly patterned burgundy and silver foliage and showy light pink flowers in mid spring. It wants grood drainage and a neutral pH and is hardy to at least USDA Zone 4. Allan Armitage gave it the highest rating of any dark-foliaged Heuchera in the 2001 University of Georgia trials
