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!
Heucheras are also salt tolerant. They are useful in the north along pathways which are salted in winter or for people gardening in coastal regions. Occasionally in northern regions, heucheras have a tendancy to heave out of the ground because of the freeze/thaw cycle. To combat heaving, add an extra layer of compost around the plant's roots in the fall. In the spring, if the plants have heaved at all, the new roots will grow into the fresh new layer of compost.
