Ecology

Found in a wide variety of damp, grassy habitats, this rhizomatous perennial herb is particularly common in areas influenced by man: waste ground, tracksides, roadside verges and hedge-banks. It is also frequent, however, in rough grassland, hayfields, and occasionally sand dunes, marshes and damp, open woods. It avoids highly acidic, infertile soils. 0-470 m (Hartside, Cumberland).
