About the species

Identification

Perennial 10–30 cm, softly bristly. Stems branch from the base. Two leaf types: on the spring flower shoot the leaves are narrow and without stalks; in summer a low circle of long-stalked leaves grows from a creeping underground stem; these are large, broadly heart-shaped with a pointed tip and plain green (no pale spots). Flowers are in loose, one-sided curls; about 1.5 cm long, funnel-shaped, opening pink to red and turning blue. Seeds come in fours; each small and dark with a pale tip that attracts ants. Differs from garden Spotted Lungwort, which has white-speckled leaves. Flowers in Finland in May–June.
