Pulmonaria - Lungwort

Fast growing, long-lived, clump forming perennials that are often evergreen and very often making excellent groundcover that is resistant to deer. They look excellent in the woodland understory, especially when combined with Primulas.
The flowers are tubular in shape and are borne during spring. They are known to attract hummingbirds.
Most are hardy zones 3 to 8 ( unless otherwise noted ) and prefer partial shade ( tolerate full shade ) on moist, fertile, well drained soil. Prune off winter damaged foliage in very early spring to make room for fresh new foliage.
Pest and disease problems are few, however mildew can occur on the foliage of some species especially when plants are stressed.
Propagation can be achieved from division during fall or very early spring or seed sown in containers during spring then later transplanted.
