Midnight Rose Coral Bells is a Heuchera plant, of which there are many varieties. Coral bells are the flowers that sprout up from the plant; they resemble tiny little bells from which they get their name. The Midnight Rose has deep purple leaves that almost look black. They fade into a lighter purple and have streaks of hot pink and spots of cream as the summer wears on. The coral bells that rise from the Midnight Rose's foliage are white. These plants are hardy in gardening zones 4 through 9.
Choose a location that has full sun to partial shade. The warmer your climate, the more important a little afternoon shade will be to this plant. Plant in early spring.
Dig a hole for each plant that is twice the diameter and a couple inches deeper than the container you purchased it in. Keep plants at least 3 feet apart from each other, or leave 2 feet from existing plants so the Midnight Rose has room to grow to maturity without being crowded.
Combine the dug-out soil to a ratio of one part compost, one part peat moss and one part soil. Mix well and fill in the hole with the amended soil to the level which you will be placing the root ball. The plant must be at the same level it is in the container.
Place the root ball in the hole and fill with an inch of soil. Water in the soil to compact it around the roots. Continue filling and watering until the soil completely surrounds the roots and is level with the surrounding soil.
Water the Midnight Rose to keep the soil moist. These plants do not like to dry out, so if you notice the top of the soil is dry, water generously. Water it at least every other day during the spring and summer, then cut back watering to once every 3 or 4 days in the fall.
Fertilize with a slow release fertilizer in the fall. Repeat the fertilization in the spring and again the following fall.
Pinch off flower stems when flowers start to die off. Doing this each time will cause the plant to put out more flowers in the spring. Cut back the foliage early in the following spring to encourage new growth.
Mulch with a pine bark or pine needle mulch for the winter. This will nourish the plant with nitrogen and keep the roots warmer during freezes. It will also decompose, and can be worked into the soil the following year.
