|discussion=<p><i>Physocarpus intermedius</i> often has been treated as a variety of <i>P. opulifolius</i>; it can be distinguished by its densely hairy young carpels that remain hairy, at least on the sutures of the follicles. The species generally inhabits somewhat drier habitats than does <i>P. opulifolius</i>.</p>
