One of the easiest perennials to grow, heuchera aka coral bells are virtually carefree. Here are the basics:
- Hardy in USDA zones 4-9, coral bells are tolerant of a wide range of light conditions, poor soil, heat, cold, humidity and drought.
- Foliage comes in nearly every color imaginable, from silver to nearly black. Leaves are patterned, ruffled, wavy or smooth.
- Flowers occur in hues of coral, red, white or pink and are attractive to butterflies and hummingbirds, and are long-lasting in cut arrangements.
Soil: Heuchera does best in rich well-draining soil, but is tolerant of clay or rocky soils and salt. If you have heavy clay garden soil, amend it to improve the drainage before planting your new coral bells or plant them in a raised bed.
Watering: Keep soil evenly moist but not soggy. Heuchera is somewhat drought-tolerant once established. Provide extra water during hot spells.
Fertilizing: In spring, spread a thin layer of compost or apply a balanced slow-release granular fertilizer around the base. For container-grown plants, supplement with a water-soluble fertilizer according to instructions.
Pruning: Trim back tattered foliage in early spring.
Pots: Coral bells grow beautifully in containers. Just make sure there is a hole in the bottom where the excess water can drain from. Transplant into the landscape in early fall if you'd like them to come back again next year. If you garden in zones 6b or warmer, they can be overwintered in containers.
