Lungworts are among the most dependable and showy spring-blooming perennials for shady locations. This selection has clusters of large violet-blue bells, over a stunning mound of heavily silvered green leaves. Cut plants back to 3 inches after blooming, to rejuvenate the foliage. Evergreen in mild winter regions. Powdery mildew is sometimes a problem; use a fungicide to prevent this. Plants prefer a rich, moist soil without the competition of surface-rooted trees.
