Heucherella 'Heart of Darkness (PP#14,489) combines the leaf coloring of Heuchera and Tiarella in a dramatic manner. 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. In the spring 'Heart of Darkness' produces branching spikes of pure white flowers to about 24". 'Heart of Darkness' has the cultivation requirements of Tiarella, that is, it should be given rich, moist, humusy soil in light shade. |
