Enliven an existing shade garden with these easy-care perennials. In April and May, Lungworts are topped with clusters of delightful blossoms in colors ranging from raspberry pink to icy blue. Most have lavishly dappled, silvery foliage that brightens shady nooks all season long. Plants spread slowly to form an attractive ground cover, and they are great companions for Bleeding Hearts, Hostas, and spring-flowering bulbs.
