This tuberous perennial herb grows on a variety of neutral and calcareous soils, and is most frequent in woodland, coppices and calcareous grassland. However, it also occurs in hedgerows, scrub, on roadsides and railway banks and on limestone pavement and moist cliff ledges. 0-880 m (Caenlochan, Angus).
This species, mapped as `all records` in the 1962 Atlas, has declined in some areas, particularly C. England and parts of Scotland. Most losses are due to woodland felling and coniferisation, intensification of grassland management and ploughing. However, it is much better recorded now, especially in Ireland.
European Temperate element.
