|discussion=<p><i>Quercus palustris</i> is especially common in landscape and street plantings. Its persistent dead branchlets (pins) and branching pattern (drooping lower branches, horizontal middle branches, ascending upper branches) are quite distinctive.</p><!--
--><p>This species reportedly hybridizes with <i>Quercus coccinea</i> (E. J. Palmer 1948) and with <i>Q. imbricaria</i> (= Q. ×exacta Trelease), <i>Q. marilandica</i>, <i>Q. nigra</i>, <i>Q. phellos</i> (= Q. ×schochiana Dieck), <i>Q. rubra</i>, <i>Q. shumardii</i>, and <i>Q. velutina</i>.</p><!--
--><p>Some Native American tribes used infusions prepared from the bark of <i>Quercus palustris</i> to alleviate intestinal pains (D. E. Moerman 1986).</p>
