A short-lived perennial herb that is most prominent in lightly shaded habitats such as hedgerows, coppices, and woodland clearings and rides. It can, however, survive in deep shade in a non-flowering form. It also occurs in coastal habitats, including sheltered cliff-top grassland and scrub, rock crevices, sea-bird rocks and stabilised shingle, and is also found on montane screes and cliffs. 0 - 1065 m (Lochnagar, S. Aberdeen).
There is no change in the distribution of S. dioica since the 1962 Atlas.
European Boreo-temperate element; also in C. Asia.
