Heuchera Obsidian is a clump-forming, coral bells hybrid that is noted for its dark purple to almost black leaves that remain dark throughout the growing season. The rounded, lobed, long-petioled leaves form a compact basal mound to 8-10” tall and 16” wide. Small, creamy-white flowers borne in open, airy panicles appear in late spring to early summer on slender, wiry stems rising well above the foliage mound, typically 20-24” tall. Obsidian is a dark-colored to black volcanic glass that is often used as a gemstone.

Additional Information

Heuchera, commonly called coral bells or alumroot, is a genus consisting of about 55 species of evergreen to semi-evergreen herbaceous perennials which are all native to North America. Plants grow in a variety of different habitats including woodland areas, Appalachian seeps, prairies, rocky cliffs, and alpine slopes.

Plants range in size from dwarf alpine plants with flower spikes rising to only 5 inches tall to much larger woodland plants with flower spikes towering to 36 inches tall. Species plants are primarily native to the West, particularly in the Rocky Mountains, with a few species extending into northern Mexico. However, some important species are native to woodland areas in the East and Southeast.

The first significant hybrid heucheras were introduced into commerce around 1980, with the volume of new introductions increasing to almost avalanche proportions in recent years. Hybrids have now supplanted species plants in the marketplace. Species plants most frequently used in producing the hybrids of today are H. sanguinea, H. americana, H. micrantha, H. villosa and H. cylindrica.

Leaves of hybrid plants are available in an expanded variety of colors including various shades of green, blue-green, violet, purple, maroon, bronze, silver-black, orange-yellow, yellow, or red, but often with a streaked, mottled, or marbled variegation which sometimes includes bold contrasting veins. Flowers of hybrid plants are also available in a variety of different colors including various shades of white, pink, coral, or red.
