Heuchera Bressingham hybrids (coral bells) are hardy, flowering perennial plants that grow best in USDA hardiness zones 3 through 9, withstanding minimum winter temperatures down to an impressive -35 degrees F. The plant blooms from late spring through mid-summer in bell-shaped flowers in shades of red, pink and white. The coral bells Bressinghams are low-growing and mounding, spreading 12 to 18 inches wide and up to 2 feet tall. You can grow your coral bells in containers or outdoors in clumps or along borders, in moist but well-draining soil with a neutral soil pH.
Select a planting site for your coral bells Bressingham hybrids that is in full sunlight to partial shade. Coral bells can grow in a wide range of soil types, but avoid planting them in heavy clay soils.
Dig a planting hole that is 1 ½ times the depth and width of the nursery container. Work into the displaced soil generous amounts of peat moss and organic compost or aged manure, so that you have a half-and-half mixture of soil amendments and displaced dirt.
Place the coral bells plant into the planting hole, and backfill the hole with the amended soil. Pat down the soil with your hands, and water the soil deeply and generously to remove any air pockets around the roots.
Water your coral bells Bressingham hybrid deeply once or twice each week to supplement rainfall. Keep the soil evenly and thoroughly moistened at all times during the spring and summer.
Feed your plant a liquid flower fertilizer once each month through the spring and summer, according to the directions on the label. Apply the fertilizer while watering the plant.
