Pulmonaria officinalis
herbLungwort (Pulmonaria officinalis) is a much-loved low perennial for shade, forming clumps of rough, oval leaves boldly spotted with silver-white, above which clusters of funnel-shaped flowers open pink and age to blue in early spring - often both colors at once on the same plant. Among the first flowers of the year, it is a vital early nectar source for bumblebees. The spotted leaves gave rise to its name, and the foliage is the part traditionally gathered. It is a hardy, easy, weed-suppressing groundcover for the damp, shady spots where many plants sulk.

Lungwort thrives in partial to full shade in rich, consistently moist, humus-rich soil - a classic plant for under deciduous trees and shrubs and along the north side of the house. Plant divisions or transplants in spring or fall, spacing them about 12 in. apart to knit into a groundcover. Keep the soil moist, especially in any sun, as dry soil and too much sun scorch the leaves and invite mildew. It is low-maintenance: shear off tired, mildewed, or scorched foliage after flowering and fresh leaves replace it. Divide crowded clumps every few years in fall.

The main issue, worst in dry soil - keep the ground moist, cut back affected leaves after bloom, and ensure airflow
May graze new leaves in the damp shade - use grit, traps, or hand-picking
Gather the leaves in spring and early summer while they are fresh and unblemished, before any midsummer mildew sets in, and dry them in a shaded, airy spot. The young leaves can also be used fresh. Cutting the clump back after flowering both refreshes the foliage and gives a clean second flush of leaves to pick.
Lungwort is grown mainly as a traditional herb and an ornamental rather than a food - the leaves were historically dried for tea, and the very young leaves are occasionally added to salads. Its standout garden value is as one of the earliest nectar plants for bumblebees and as a handsome, silver-spotted groundcover that lights up shade.
