Heuchera vs heucherella
Heucherella, or foamy bells, is a cross between coral bells (Heuchera) and foamflower (Tiarella). It takes the coloured leaves of coral bells and the lobed, often dark-veined leaf and frothy spring flowers of foamflower, and it takes more shade and moisture than coral bells. Coral bells come in the wider range of leaf colours and take more sun. With either, repeat one leaf colour along a bed rather than mixing several.
