Original caption: These hardy perennials are mainly natives of North America. Alum root, as they are commonly called, grow from 12 to 18 inches high. Some types are mainly grown for the beauty of their foliage and others for their dainty flowers. Not many wild types are now grown in gardens, because many beautiful named varieties have been developed which provide an abundance of pretty flowers. --- Image by © David Roseburg/CORBIS
