|discussion=<p><i>Dichanthelium boreale</i> grows in open woodlands and thickets, wet meadows, and fields. It is restricted to the Flora region. The primary panicles are mostly open-pollinated and are produced in May and June; the secondary panicles are predominantly cleistogamous and are produced from mid-June into October.</p><!--
--><p><i>Dichanthelium boreale</i> occasionally hybridizes with <i>D. acuminatum</i> and <i>D. xanthophysum</i>, producing a sterile triploid sometimes called <i>Panicum</i> calliphyllum Ashe.</p>
