Ranked as one of the best Heuchera, award winning Heuchera 'Obsidian' is a particularly attractive variety of Coral Bells with its foliage of lobed, rounded, long-petioled, rich dark purple to almost black, shiny leaves that remain dark throughout the growing season and do not fade.
- 'Best New Plant' Award at the 2008 Woking Nursery Exhibition in England.
- In early-mid summer, panicles of small, bell-shaped, creamy-white flowers bloom on slender stems rising up to 24 in. (60 cm) above the semi-evergreen foliage. This sport of Heuchera 'Obsidian' is prized by gardeners for its vigor and consistent performance under a variety of garden conditions and good resistance to powdery mildew.
- This clump-forming perennial forms basal mounds, up to 10 in. tall (25 cm) with a spread of 16 in. (40 cm). This sturdy performer is not only easy to grow, but also requires little maintenance and is pest and disease free!
- Performs best in part shade, in rich, humusy, medium moisture, well-drained soils. If grown in full sun, make sure the soil remains consistently moist or the foliage might decline. Thrives in dry shade, once established. It is attractive to butterflies and often ignored by deer.
- A spectacular addition to beds, borders, rock gardens, woodland gardens and is ideal as groundcover, edger along paths or in containers. Fabulous when planted in groups!
- Divide clumps in spring every 3-4 years.
- Remove stems of faded flowers to promote additional bloom. Apply winter mulch after the ground freezes to help prevent root heaving.
