Coral bells is a traditional perennial foliage plant, with new varieties introduced 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 begin 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. Besides traditional green-leaved coral bells, newer varieties have leaves in shades of purple, rose, lime green, gold, and more. Coral bells are best planted in late fall or early spring and will grow at a moderate pace, making them a great option for woodlands, rock gardens, containers, borders, and ground covers. But they are short-lived perennials; unless divided regularly, they will die out in a few years.
