Heuchera sanguinea "White Clouds" (Coral Bells, Alum Root)
I like this Coral Bells not just because the flowers are white but also because there are just so many of them. They are long lived on this 12-18-inch plant, and they also make excellent cut flowers. But that's not all: the marbled foliage makes an attractive plant with or without the spires of diminutive blooms. Give this Heuchera extra shade to maintain the marbled foliage in Zones 3-10. Part shade. Quarts.
