English ryegrass (Lolium perenne L.) comes originally from England, where it has been grown since 1680. The study presents the most important morphological and biological features of Lolium perenne. Because of those mostly positive features Lolium is very suitable to different turf use (on gazons, sport fields, recreations area and so on) Lolium perenne is able to produce more than 10 thousand tillers per 1 m², has a good ability to different management, good response for nitrogen fertilisation and it is resistance for low and frequently cutting. Some of Lolium disadvantages do not change the opinion that it is one of the most important turf grasses in Poland and Europe.
