Pulmonaria 'Cobalt' is a compact, clump-forming perennial known for its striking cobalt-blue flowers that appear in late winter to early spring. The flowers emerge above a mound of deep green leaves lightly spotted with silver, adding interest even after flowering. Typically growing to 25 to 30 cm high and 30 to 40 cm wide, it is ideal for cottage, woodland, and shaded border garden styles. Plant in partial to full shade with moist, humus-rich, free-draining soil. Space plants 30 to 40 cm apart to allow for natural clump development. Cut back old leaves after flowering to encourage fresh growth. Mulch annually to retain soil moisture and suppress weeds. A hardy, low-maintenance perennial that brings early colour and texture to shaded garden areas. HEIGHT: 35cm WIDTH: 45cm aka Bethlehem sage
