|discussion=<p>A. R. Kruckeberg (1996) noted that a population similar to <i></i>subsp.<i> purshiana</i> was discovered on serpentine slopes in the Wenatchee Mountains of Washington. In their shrubby habit, these plants appear to be differentiated from non-serpentine populations elsewhere in the Pacific Northwest, which are treelike in habit. The Wenatchee plants retain their shrubby habit when garden-grown from seeds.</p><!--
--><p>The bark of <i></i>subsp.<i> purshiana</i> is a valuable medicinal crop for its cathartic properties. The tree attracts an abundance of bees and other pollinators during its long flowering season, and the fruits are an important food for songbirds, pileated woodpeckers, band-tailed pigeons, and other wildlife.</p>
