A tuberous perennial herb of both dry and moist chalk and limestone grasslands, limestone pavement, less acidic heaths, and wetter habitats such as base-rich fens. It also grows in artificial habitats, including quarries and railway banks. 0-610 m (Ben Lawers, Mid Perth).
This species was mapped as `all records` in the 1962 Atlas. It has declined throughout its range, probably due to habitat destruction, ploughing of pastures and drainage. Three subspecies are currently recognised, although each may deserve specific rank (Bateman et al., 1997); they are mapped separately.
Eurasian Boreo-temperate element.
