ON THIS PLANT

Pulmonaria angustifolia, the narrow-leaved lungwort or blue cowslip, is a species of flowering plant in the family Boraginaceae, native to central and north eastern Europe. Growing to 30 cm (12 in) tall by 45 cm (18 in) broad, it is an herbaceous perennial with hairy oval leaves and masses of bright blue flowers in spring. The subspecies azureus has brighter blue flowers.The specific epithet angustifolia means "narrow-leaved". Despite the common name "blue cowslip" it is not closely related to the true cowslip (Primula veris). In cultivation it prefers moist soil with dappled shade.

CARE GUIDE

How to keep Pulmonaria Angustifolia.

Light

Pulmonaria mollis subsp. mollis occurs naturally in habitats like forest understories and rocky areas, where it grows in natural shade. It prefers partial sun but can tolerate both full sun and full shade, showing its adaptable and hardy nature.

Water

Cowslip lungwort flourishes in moist, well-drained soil with consistent humidity, reflecting its woodland origins. Although moderately drought-tolerant, it benefits from weekly watering. Planting it in containers can help manage moisture effectively, preventing waterlogging and promoting health and vigor for this herbaceous perennial.

Temperature

Pulmonaria mollis subsp. mollis can adapt to a wide range of temperature conditions, although its distribution may still be limited by various combinations of water and heat. It grows best in warm summers with adequate rainfall or watering. Extended periods of cloudy, rainy weather or prolonged high temperatures can increase the likelihood of Pulmonaria mollis subsp. mollis dying. In winter, proper protection from cold can improve the plant's survival.

Fertilizer

The best time to fertilize Pulmonaria mollis subsp. mollis is in early spring, as it comes out of dormancy and begins active growth. Fertilization supplies essential nutrients needed for healthy development. While this subspecies has relatively low fertilizer requirements, feeding it once a year can improve its survival and encourage better, longer-lasting flowers.

Pruning

Cowslip lungwort showcases beautiful blue flowers and leaves with distinctive spots. To encourage healthy growth, prune the plant from early to late spring, right after it finishes flowering. Remove any spent blooms and damaged foliage during the pruning process. Additionally, thinning older stems will enhance airflow and improve the plant's overall health. Make sure to use clean, sharp tools for the best results.
