A rhizomatous perennial herb of freely-draining, nutrient-poor soils. It is most frequent in Fraxinus woods on limestone in N. and W. Britain, but also grows in the grikes of limestone pavement, in acidic woods in S.E. England, and in a fen in Cumbria. It is a common garden escape. 0-470 m (Carreg-goch, Brecs.).
The native distribution of C. majalis is probably stable, but is now very largely obscured by naturalised plants. It is often difficult to separate native and alien plants and the map must be regarded as an approximation. Many of the losses had occurred by 1930.
European Boreo-temperate element; also in E. Asia and widely naturalised outside its native range.
