Obsidian Heuchera

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.
