Heuchera plants form round mounds with a woody rootstock or crown at their base. Small bell-shaped flowers on tall stems attract hummingbirds and make nice cut flowers. Their leaves are rounded, lobed, hairy, and evergreen—even when covered in snow. Besides traditional green-leaved coral bells, new varieties of heuchera have leaves in shades of purple, rose, lime green, gold, and variegations in between. Heuchera are native North American plants that are at home in woodlands, rock gardens, containers, borders, and when used as ground covers.
