|discussion=<p><i>Eurybia radulina</i> is confined mostly west of the Cascades, from southern Vancouver Island (British Columbia) to the southern Coast Ranges, north Channel Islands, and central Sierra <i>Nevada</i> in California. It often is confused with <i>E. merita</i> in the western, coastal states where both are found, though populations are rarely if ever sympatric, the former apparently thriving at lower elevations than the latter.</p>
