Pulmonaria longifolia, the narrow-leaved lungwort,[1] is a semi-evergreen clump-forming herbaceous perennial plant, native to western Europe, including Britain, France, Spain, Portugal.

It grows in semi-shaded habitats, such as woodland and scrub, to 2000 m above sea level.

The flowers are funnel-shaped, carried in short hairy cymes in spring.

The corolla is 8–12 mm long, pink turning blue or violet.
