A perennial herb of base-rich marshes and fens, calcareous flushes on peaty soils, stony and muddy areas with seeping water, wet paths and short turf on banks; also in coastal cliff-flushes, dune-slacks and in the upper parts of saltmarshes. It requires open sites and is often dependent on grazing, cutting or disturbance. 0-915 m (Atholl, E. Perth).
Many lowland sites for this species were lost in the 19th century. Since the 1962 Atlas it has been lost from half the extant 10-km squares in lowland England, because of drainage and lack of grazing. It is easily overlooked and is now better recorded elsewhere.
European Boreo-temperate element; also in C. and E. Asia and N. America.
