As a smaller plant, the heuchera, commonly called coral bell, is a versatile perennial that works well in large masses or as an accent plant for almost any garden. Although coral bells produce a delicate stem of beautiful, bell-shaped flowers that extend over the plant in the early summer, they are grown mostly for their unique leaf colors. The perennials tend to be evergreen, holding their leaves through the winter months, although that depends widely on the severity of our winters.
