'Bertram Anderson' lungwort (Pulmonaria longiflora 'Bertram  Anderson') Genus:  Pulmonaria ‘Bertram Anderson’ is an older cultivar of lungwort with excellent foliage. In early spring, pink buds open to bright blue flowers, then silver-spotted leaves unfurl for a season-long show. Lungworts can have mildew problems, but ‘Bertram Anderson’ is highly resistant. When you cut off the old foliage in late winter, wear gloves; the tiny hairs all over the leaves (which keep the deer away) can irritate your skin. -Irvin Etienne, Fine Gardening #147 (October 2012), page 72 Noteworthy Characteristics:  Speckled foliage and periwinkle blue flowers. Perfect dose of cool color in shade. Care:  Cut away old foliage in winter. Propagation:  Divide after flowering or in early fall. Plants grown from seed may not look like their parents, as lungworts hybridize freely in garden settings. Seeds should be sown when ripe. Problems:  Powdery mildew is a common problem to lungworts, especially in overly dry conditions, but 'Bertram Anderson' is a resistant cultivar.
