Heuchera 'Southern Comfort'

Soil: Coral bells like well-drained soils that are rich in organic matter.
Light: As a general rule, they do well in shade, but for the brightly colored varieties, some morning sun ensures best color development. The color can wash out in full sun, and too much heat and light can cause the leaves to scorch.
Water: Average -- it's better to err on the side of caution and keep heuchera on the dry, rather than the wet, side. Keep the soil evenly moist, but not consistently wet to prevent root rot. In nature, heuchera are typically found growing between rocks.
Spacing: 2 ft
Fertilizing: spread a layer of compost or rotted manure in early spring. Mulch is a good idea, but keep it from mounding on the crown (center) of the plant. Heuchera does not require fertilization during the fall or winter months.
Winterizing: Winter mulching will prevent the freezing and thawing that can heave plants roots.
Maintenance & pruning: Cut back the entire flower stalk after flowering to put the plants energy into growing more leaves.
