A tufted or mat-forming perennial herb found in a wide range of, usually fertile, habitats including neutral pastures and meadows, calcareous and acidic grassland, fen-meadows, rush-pastures, heaths and mires, springs and flushes, montane grassland, rocks and ledges, sand dunes and shingle, cultivated ground, waste places and walls. 0-1220 m (Aonach Beag, Westerness).
The distribution is similar to that in the 1962 Atlas. Subsp. vulgare and subsp. holosteoides are common throughout the range of the species, although the latter is more frequent in the north; subsp. scoticum is mapped separately.
Eurosiberian Boreo-temperate element, but widely naturalised so that distribution is now Circumpolar Boreo-temperate.
