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 generally prefers some shade (particularly in the heat of the afternoon) in the south. If grown in full sun, consistent moisture is important. Scorch and general foliage decline tend to occur if soils are allowed to dry out. Remove stems of faded flowers to encourage additional bloom. Some gardeners prefer to remove flower stems before flowering if plants are being grown as ground covers for their foliage texture and color. A mulch applied after the ground freezes will help prevent root heaving. Divide clumps in spring every 3-4 years.
‘Mahogany’ is a vigorous, clump-forming coral bells cultivar that is noted for its mahogany leaves. It typically grows in a dense basal mound to 8” tall and to 16” wide. Rounded, lobed, ruffled leaves emerge mahogany with purple tones in spring, but mature to mahogany-red by summer. Tiny creamy white flowers appear on slender stems rising above the foliage mound to 14” tall in summer. U. S. Plant Patent PP19,072 was issued on August 5, 2008.
No serious insect or disease problems. Frost heaving of roots may occur when winter temperatures fluctuate widely.
Effective in groups or massed as a ground cover. Also effective as a specimen or accent. Rock gardens, borders and open woodland gardens. Interesting as an edger along paths or walkways. Containers.
