Obsidian Coral Bells

Heuchera ‘Obsidian’ Obsidian Heuchera is prized for its dramatic, near-black foliage that provides rich color and contrast throughout the growing season. Its large, glossy leaves retain their deep coloration better than many other dark-leaved coral bells, making it a standout in shade gardens, borders, and containers. In late spring to early summer, delicate creamy white flowers rise above the foliage on slender stems, attracting hummingbirds and other pollinators. Compact, evergreen in mild climates, and easy to grow, Obsidian Heuchera adds year-round texture and bold color to the landscape. It thrives in well-drained soil and is an excellent choice for brightening shaded spaces or complementing flowering perennials.
