An early-flowering tufted but shortly rhizomatous herb of various grassy habitats, preferring more acidic soils and more shaded places than L. campestris. It occurs on heaths and moors and in the drier parts of bogs, in meadows and other grassy places, and in open woods and wood margins. 0-1020 m (Breadalbanes, Mid Perth).
Because of past and present confusion with L. campestris, it is difficult to assess the validity of the apparent decline of this species in C. &. E. England. Subsp. multiflora and subsp. congesta are difficult to distinguish and are unevenly recorded; they are not mapped here.
Circumpolar Wide-boreal element; widely naturalised outside its native range.
