In the garden
Pulmonaria longifolia is a European herbaceous perennial in the borage family that is valued for spring flowering in shady parts of the garden. Its flowers change from pink to blue or violet and appear in the main spring months of March to May. Sit it where it will receive partial shade or full shade, particularly on north, east or west-facing aspects and in sheltered positions. Soil is important: choose a moist, well-drained, humus-rich site with neutral to alkaline pH and avoid drought-prone corners. Mulching with organic material will help the soil retain moisture and supply humus as it breaks down. The plant tolerates semi-shade and will perform where light levels are lower than for many spring-flowering perennials. Use Pulmonaria longifolia as a ground cover or as part of a woodland or shade garden where its spring flowers can be seen before denser summer foliage fills the border. Because it is fully hardy (H7) it withstands UK winters in situ. The pink-to-blue colour shift in its spring flowers is a reliable seasonal marker for shady borders between March and May.
