Mediterranean hairgrass is a small annual grass native to the Mediterranean, Macaronesia, parts of Asia and the Himalaya, and now naturalised in parts of Australia. It is a weed of lawns, pastures and disturbed ground rather than a plant grown for ornament, so it is best kept in check by mowing or hand removal before it sets seed.
