|discussion=<p><i>Deschampsia flexuosa</i> grows on dry, often rocky slopes, and in woods and thickets, often in disturbed sites. In the Flora region, it is primarily eastern in distribution, with records from west of the Great Lakes and Appalachians probably being introductions. It is also known from Mexico, Central America, South America, Borneo, the Philippines, and New Zealand.</p>
