A perennial herb of damp or wet habitats on a wide range of soils, including fen- and water-meadows, rush-pasture, marshes, streamsides, wet heath, springs and flushes on hill slopes and occasionally in wet woodland. It is also established from cultivation in churchyards, and on roadsides and waste ground. 0-770 m (Cross Fell, Cumberland).
A. ptarmica was mapped as `all records` in the 1962 Atlas. It is now better recorded in some areas, but has declined in others. Analysis of the database reveals that while many losses occurred before 1950, they have accelerated since then; most are due to drainage and habitat destruction.
Eurasian Boreo-temperate element; widely naturalised outside its native range.
