Coral Bells are also prized for their large, almost heart-shaped leaves, some ruffled, with striking color variegation. The foliage grows in mounding 10-12" clumps and prefers part to half shade, along with evenly moist and well drained soil. Above is one of my favorites, Snow Angel, with it's unique white and green mottled leaves and brilliant pink flowers.
There are many cultivars with clever names like Creme Brulee, Green Spice and Peach Melba. Another favorite, this Lime Marmalade makes a stunning contrast to surrounding plants with it's chartreuse leaves and white flowers.
As far as propagation, they do not self sow in the garden but respond well to division in early spring.
Sashay has deeply cut dark green leaves with a surprising burgundy contrast on the underside. I think their ruffled leaves add a whimsical touch to the garden.
Here in the West, Heuchera's tend to heave themselves out of the ground slightly during the winter. So every spring, I trim the undergrowth for a more shapely appearance and add fresh soil around the base of the plant.
