Obsidian is the result of volcanic lava coming in contact with water. This process results in a glassy finish. Heuchera 'Obsidian' PP14836 exhibits this same glassy sheen and is closer to black than any other heuchera. The surface and edges of the rounded leaves are so smooth they look like they have been polished. Their undersides are deep purple and exhibit the same glassy finish.
Though this selection is grown mainly for its unusual foliage, its ornamental value is enhanced by the 24 inch tall scapes which bear smoky purple buds that open to cream flowers.
This selection forms a very compact, tight mound of foliage, making it ideal as an edging or in containers. It's fabulous when paired with brightly colored flowers and foliage in the garden. This new variety is destined to become a favorite!
Coral bells are easy to grow and blend easily with most other perennials in the landscape. Because of their low, mounding habit, they are often used as edging along paths or in containers.
