1.Pulmonaria Officinalis — Overview
Pulmonaria officinalis, commonly known as lungwort, common lungwort, or Jerusalem sage, is a charming herbaceous perennial native to woodlands, hedgerows, and shaded banks across Europe. This member of the Boraginaceae family, which also includes borage and forget-me-nots, is distinguished by its distinctive basal rosette of ovate to cordate leaves. These leaves are typically hairy and often feature prominent white spots or blotches, a characteristic that historically contributed to its use in traditional medicine under the 'doctrine of signatures' for lung ailments.
Growing up to 15 cm long, the foliage provides a striking backdrop for its early spring blooms, from March to May. The plant produces clusters of funnel-shaped flowers that display a fascinating color transformation: emerging as pink buds, opening to vibrant pink, and gradually shifting to deep blue or violet as they mature. This chromatic change is attributed to fluctuations in the pH level within the flower petals.
Pulmonaria officinalis spreads slowly via rhizomatous roots, forming attractive groundcover and serving as a vital early-season nectar source for bees and various other pollinators. It thrives in moist, well-drained soil and prefers partial to full shade, making it an excellent choice for woodland gardens and shaded areas.
