Pulmonaria ‘Cotton Cool’
Plant number: 1.449.560
Lungworts are among the most dependable and showy spring-blooming perennials for shady locations. This British selection features clusters of sapphire-blue bells over a lush mound of long, arching silver leaves. Cut plants back to 3 inches after blooming, to rejuvenate the leaves. Evergreen in mild winter regions. Good resistance to powdery mildew. Plants prefer a rich, moist soil without the competition of surface-rooted trees. Clumps are easily divided in early autumn.
