Pulmonaria 'Blue Ensign' is a strongly performing ground covering perennial to 30cm tall, with broad, dark green leaves and compact clusters of large and vivid, violet-blue flowers in spring. A well behaved variety of pulmonaria spreading to just 50cm maximum. Excellent ground cover for a shady area where the soil is moist and rich. Grows in most types of soil, provided they are well drained, and will grow in anything from partial sun to full shade.
