probably the first grass deliberately sown for pastures’. As a result it has been sown in many countries and has become extremely widespread both as a cultivated species for livestock grazing and for fodder (as hay or silage), and as a useful cover crop for soil stabilisation and pasture improvement, as well as an excellent grass for lawns and turf.
Can form a dense turn which can outcompete native vegetation. Produces large quantities of seed which is easily dispersed. Deliberately sown as a forage crop, for erosion control, and for lawns and sports fields.
