One of the most widely planted variety of Coral Bells, award-winning Heuchera micrantha 'Palace Purple' features very large, lustrous, star-shaped leaves, ranging in colour from deep olive green to purplish-bronze to brilliant deep purple. Their undersides are a striking metallic amethyst purple. In late spring to midsummer, panicles of small, bell-shaped, creamy-white flowers bloom on slender, dark red stems rising up to 20 in. (50 cm), well above the evergreen foliage. A great addition to the rock garden, perennial border, as edging along paths or in containers.
