A perennial herb of wet grassy places on moderately fertile, seasonally waterlogged soils in woods, wet meadows, fens and flushes. In upland areas it is also found in rush pasture and bryophyte-rich springs. It occasionally persists in gardens and lawns. It is morphologically and cytologically variable, many clones reproducing by rooting from the leaves. 0-1080 m (Ben Lawers, Mid Perth).
There has been no change in the overall distribution since the 1962 Atlas. Although many of its lowland habitats have been improved, C. pratensis is resistant to some herbicides and can survive in semi-improved pastures.
