|discussion=<p><i>Holcus</i> lanatus grows in disturbed sites, moist waste places, lawns, and pastures, in a wide range of edaphic conditions and at elevations from 0-2300 m. A native of Europe, it was widely distributed in North America by 1800. It is an ancestor of the polyploid complex represented by <i>H. mollis</i>. In Europe, it hybridizes with tetraploids of <i>H. mollis</i> to form a sterile triploid that spreads vegetatively.</p>
