A perennial herb found on sea-cliffs, rocky shores, in coastal grasslands and the uppermost parts of saltmarshes; usually growing in bare rock-crevices or on free-draining sandy or gravelly substrates, but also in flushes and seepage zones on cliffs, and where streams debouch onto the shore. Inland, it occurs in wet meadows, marshes and fens on mineral-rich soils. Lowland.
There has been little change in the distribution of C. distans since the 1962 Atlas, although it has declined inland due to the drainage and improvement of its wetland habitats.
European Southern-temperate element.
