|discussion=<p><i>Holcus mollis</i> grows in moist soil and disturbed sites, including lawns and damp pastures. It is a European introduction that has persisted in the Flora region, becoming a problematic weed in ungrazed pastures, prairie remnants, and oak savannahs in portions of the Pacific Northwest. It is also sold as an ornamental. There are two subspecies: <i>Holcus mollis</i> L. <i></i></i>subsp.<i><i> mollis</i> (stems not thickened and tuberous at the base; panicles lax, brownish or purplish) and <i>H. mollis</i> subsp. reuteri (Boiss.) Malag. (stems thickened and tuberous at the base; panicles narrow, whitish). North American introductions belong to <i></i></i>subsp.<i><i> mollis</i>.</p>
