Obsidian Coral Bells, a variety of Heuchera, is a perennial plant known for its striking foliage and compact growth habit. The plant's standout feature is its dark, almost black leaves that have a glossy, smooth texture, resembling polished obsidian. The leaves are typically rounded with scalloped edges and can exhibit subtle hints of deep purple under certain lighting conditions. During late spring to early summer, slender flower stalks rise above the foliage, bearing small, bell-shaped flowers that are usually white to pale pink. These flowers attract hummingbirds and pollinators, adding a dynamic element to garden spaces.
