This tuberous perennial herb grows on neutral or base-rich soils in a wide range of habitats, including deciduous woodland, scrub, roadsides, chalk grassland, meadows, marshes, dune-slacks, fens and mildly acidic heaths. It can become abundant in artificial habitats such as waste ground, abandoned gravel-pits, quarries and railway embankments. 0?530 m (Garrigill, Cumberland).
There has been little change in the distribution of this species since the 1962 Atlas, and losses have been balanced by its ability to colonise newly available, often man-made, habitats.
Eurosiberian Temperate element.
