L. flos-cuculi is a herb of damp habitats, found in wet grassland, rush-pasture, fen-meadow, ditches, tall-herb fen and damp woodland margins. A dwarf form (var. congesta), known from exposed coastal grassland in E. Kent, Caithness, Sutherland and Shetland, apparently retains this character in cultivation. 0-750 m (Cross Fell, Cumberland).
