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).
L. perenne has been cultivated since at least the 17th century, and cultivars developed by plant breeders are currently amongst the most commonly sown agricultural grasses. Its distribution is stable.
European Southern-temperate element; widely naturalised outside its native range.
