Heucherella ‘Onyx’

True black, glossy, deeply cut leaves on a dense medium size mound make this a great landscape plant. We’ve been working for years to get a good black Heucherella. This is it. Loves heat and humidity but great in the northwest. Shy to bloom – always stays neat and clean. Great foliage for mixed containers.
