Ecology

L. perenne is predominantly a species of improved lowland pasture, leys, and hay meadows, but is found widely in other habitats, including downland, rush-pasture, inundated grasslands, amenity grassland and road verges; also in open ruderal habitats. It favours fertile, heavy, neutral soils, but is also found on those which are mildly acidic or basic. 0-570 m (Alston Moor, Cumberland).
