|discussion=<p><i>Hydrangea arborescens</i> has escaped from cultivation in Connecticut, Massachusetts, New Brunswick, and Nova Scotia; it is not native in those states or provinces.</p><!--
--><p>E. McClintock (1957) circumscribed <i>Hydrangea arborescens</i> as comprising three partly sympatric subspecies; subsp. arborescens, <i></i>subsp.<i> discolor</i>, and subsp. radiata. R. E. Pilatowski (1980, 1982) concluded that these were best treated as three species (<i>H. arborescens</i>, <i>H. cinerea</i>, and <i>H. radiata</i>), citing chemical, morphological, reproductive, and geographic discontinuities among the taxa. Most herbarium specimens are easily referred to one of these species; occasional specimens appear intermediate between <i>H. arborescens</i> and <i>H. cinerea</i>.</p><!--
--><p>The Cherokee and Delaware tribes used bark and occasionally leaves from <i>Hydrangea arborescens</i> to prepare infusions or poultices to treat various internal and external ailments. The Cherokee used peeled twigs and branches to make tea or cooked twigs and branches as a vegetable (D. E. Moerman 1998).</p>
