Description:
Pulmonaria officinalis is an evergreen perennial species of lungwort. It is a rhizomatous plant in the Borage family. In spring, it produces small bunches of pink flowers which turn to blue-purple. The plant has been cultivated for centuries as a medicinal herb, the ovate spotted leaves held to be representative of diseased lungs, following the Doctrine of Signatures.
This attractive plant is prized as a groundcover both for its striking, white-spotted green foliage and it’s pretty, tubular flowers that are pink when they first open, then fade to shades of blue and purple. It grows to a height of only 9 inches. This is a great choice for shady spots in zones 3-9 except in Florida and along the Gulf Coast.

This is a genus of about 18 species, from Europe and Asia, of deciduous or evergreen, low-growing perennials with spreading rhizomes.
Pulmonarias are grown for their early flowers and attractively spotted leaves. They are good ground cover for a shady area and can be grown in woodland, the front of a shrub border or in a wild garden.
The leaves are simple, basal, ovate to elliptic or oblong, hairy and often spotted with white or silver.
The few stem leaves are smaller and stalkless. The leaves that develop after flowering have the best markings.
Flowers are borne in terminal cymes and may be pink, red, violet, purple, blue or white. They are funnel-shaped, 5-10mm (0.25 – 0.5in) across with five petals.

Cultivation:
Lungwort is a perennial herb which is propagated by root division in autumn or seed sown directly in spring. When dividing clumps, keep them well watered to encourage good root development before winter sets in. Plants requires a shady and reasonably moist environment and the soil should be rich in organic matter. Give it a little extra water during hot spells. In winter, cut back the flowering stems and mulch well. Divide clumps three or four years after planting. The soil can be acid or alkaline.
Grow in humus-rich, fertile, moist but not waterlogged soil in full or partial shade.
Remove old leaves after flowering and divide every three to five years.
Powdery mildew may be a problem in dry conditions and slugs and snails may damage new growth.
Propagation:
Sow seed in containers outdoors as soon as ripe. However, plants raised from seed of garden specimens often do not come true.Divide plants in autumn or after flowering or take root cuttings in mid-winter.
Harvesting
Harvest the whole plant in the middle of summer during the flowering period.
Medicinal Uses
Pulmonaria comes from the Latin pulmo, the lung. According to the Doctrine of Signatures, the plant was considered to be an effective remedy for diseases of the lung because the spotted leaves were supposed to resemble diseased lungs. However, the common name in some East European languages is derived from the word for honey, probably as an indication of the attraction of the flowers to bees.
For medicinal purposes, make an infusion or tincture of leaves that have been gathered during the flowering period.
*Lungwort is traditionally used bronchial complaints. But there is little evidence to support the effectiveness of this plant.
*It has astringent properties and can be used to cleanse the digestive system, for diarreha, and for cystitis.
*It’s often used to strengthen the utereus during pregnancy and to facilitate childbirth.
*It makes a soothing gargle for hoarseness or sore throat.
*It helps to stop bleeding after passing kidney stones.
Other Uses: A tolerant and slow growing ground cover plant for open woodland and border edges. Plants should be spaced about 50cm apart each way.
