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 a similar 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. 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.
Easy to grow average soil; Heucheras will perform best in organically rich, humus, medium wet, well-drained soil with a neutral pH. Performs well in full sun in the north, but prefers some afternoon shade in the south. If grown in full sun, consistent moisture is particularly important. They grow most vigorously and have the strongest colors when grown in partial shade (preferably afternoon shade). They can also be grown in full shade but their growth rate will be very slow.
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. Remove stems of faded flowers to encourage additional bloom. Foliage is essentially evergreen in warm winter climates, but the amount of retained foliage color in cold winter climates depends upon the temperatures. In cold winter climates, winter mulch applied after the ground freezes will help prevent root heaving. Clumps may be divided in the spring every 3 to 4 years .
