Tidy mounds of colourful foliage fill in gaps in the landscape. Heuchera are also known as coral bells, named for the tiny, bell-shaped flowers that arrive in summer on tall, slender stalks. But it's the attractive scalloped leaves that steal the show. Tolerant of a wide range of soils and temperatures, this versatile ground cover will perform reliably almost anywhere. Covers 18-22 sq ft when planted together.
