Heuchera hybrid 'Obsidian' flaunts rich, broad, satiny purple-black foliage that will not fade, even in full sun! Coral Bells is a very textural plant adding interest to woodland gardens, landscapes, or large containers. Low maintenence; deadheading not necessary. Deer resistant. Deadheading won't keep them blooming longer. However, removing the flower stems once the plant has finished blooming will keep them looking tidier.
