Quick Overview:

‘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. 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.

Description

Best grown in organically rich, humusy, medium moisture, well-drained soils in full sun to part shade. Performs well in full sun in the north, but prefers some shade (particularly in the heat of the afternoon) in the south. The best foliage color may occur in sunny spots with part afternoon shade. Scorch and general foliage decline usually occur if soils are allowed to dry out. If grown in full sun, consistent moisture is particularly important. Remove stems of faded flowers to encourage additional bloom. Foliage is essentially evergreen in warm winter climates, but the amount of retained foliage color in cold winter climates depends in large part upon the severity of the temperatures. In cold winter climates, a winter mulch applied after the ground freezes will help prevent root heaving. Divide clumps in spring every 3-4 years.  (Courtesy of Missouri Botanical Gardens Plant Finder)
