Pulmonaria ‘Blue Ensign’ – Deep Blue Lungwort for Spring Shade
Pulmonaria ‘Blue Ensign’ is a classic and much-loved lungwort, valued for its intense blue flowers and handsome, unspotted green foliage. Flowering early in the season, it brings a welcome splash of colour to shaded areas just as the garden begins to wake up in spring.
From early to mid-spring, clusters of vivid, gentian-blue flowers appear above neat clumps of dark green leaves. These blooms are especially attractive to early pollinators, making ‘Blue Ensign’ an important and beneficial plant for wildlife-friendly gardens.
The foliage remains fresh and tidy long after flowering has finished, providing excellent ground cover beneath shrubs or along the front of shaded borders. Its strong colour and clean leaf shape make it a superb foil for softer woodland plants and spring bulbs.
Exceptionally hardy and easy to grow, Pulmonaria ‘Blue Ensign’ thrives in partial shade and moist, well-drained soil. Once established, it is dependable and low maintenance, returning each year with minimal fuss. A timeless choice for bringing early colour, structure, and pollinator value to shaded gardens.
