More About Heuchera ‘Black Forest Cake’

Heuchera ‘Black Forest Cake’ is prized for its deep, near-black foliage with a subtle glossy sheen that gives the plant a rich, polished look throughout the season. The rounded leaves hold their dark color exceptionally well, even through summer heat, making this one of the darkest coral bells available.

In late spring, delicate flower spikes rise above the foliage, carrying small creamy-white blooms that provide soft contrast without distracting from the dramatic leaves. Even when not in bloom, the foliage remains the star year-round.

Why We Like It (Our Trials)

In our trials, ‘Black Forest Cake’ has shown excellent vigor, color stability, and garden performance. It forms a dense, uniform mound that looks intentional in both containers and in-ground plantings.

We especially appreciate how well it anchors plantings. The dark foliage creates contrast with silvers, chartreuse, pinks, and whites, making surrounding plants appear brighter and more vibrant. It also performs reliably in containers, where its color really stands out.

Heuchera ‘Black Forest Cake’ vs. Other Heuchera

Compared to other dark-leaved heucheras, ‘Black Forest Cake’ offers deeper coloration and better heat tolerance, holding its near-black tone rather than fading to burgundy or brown.

When compared to colorful varieties like ‘Berry Smoothie,’ this selection provides dramatic contrast rather than bold color, making it ideal as a grounding element in mixed plantings. For gardeners seeking a reliable, ultra-dark heuchera with strong year-round presence, Heuchera ‘Black Forest Cake’ is an exceptional choice.
