Heucherella 'Heart of Darkness (PP#14,489) is a 2002 introduction from The Primrose Path. It was selected for its unusual foliage coloration and relatively large, showy flowers.

Growth Habit - A loose mound of 3.5 to 4"-wide leaves that is about 8" high X 14" wide. The flower stems are branched and spreading, reaching a height of about 24".

Foliage - The ground color of the foliage is green, but each leaf has a large central zone of dark maroon surrounded by silver-gray. This is seasonally variable, but when these marking are most extensive, only a narrow margin of light green is left on each leaf.

Flowers - In the spring 'Heart of Darkness' produces branching spikes of pure white flowers to about 24"

Special Features - 'Heart of Darkness' combines the leaf coloring of Heuchera and Tiarella in a dramatic manner. It has the cultivation requirements of Tiarella, that is, it should be given rich, moist, humusy soil in light shade and not be allowed to dry out.
