Coral bells is a traditional perennial foliage plant with hundreds of varieties available, and new introductions offered every year. Native to North America, the plants form round mounds with a woody rootstock or crown at their base and small bell-shaped flowers that appear in spring or early summer on the tall stems. Rich in nectar, the flowers attract hummingbirds and butterflies, plus make nice cut blooms. Their leaves are rounded, lobed, hairy, and evergreen or semi-evergreen, depending on the climate.
