Heuchera 'Dark Secret' is a striking evergreen perennial valued for its rich, dark foliage and compact growth. The glossy leaves emerge deep purple to almost black, providing bold contrast throughout the year, particularly when planted alongside lighter foliage plants. In late spring and early summer, delicate white flowers rise above the foliage on slender stems, adding a light, airy detail. Hardy and easy to grow in moist, well-drained soil, this variety is an excellent choice for shaded borders, containers, and modern planting schemes where strong leaf colour is desired.
