|discussion=<p>Eurybia surculosa is of conservation concern in Virginia and Alabama. It is often confused with E. compacta, its close relative from the coastal plains. In states where both are present, it is found only inland in the southern Appalachian Mountains and not on the coastal plains; its larger heads help to differentiate it from E. compacta.</p>
