|discussion=<p>Two poorly defined varieties of <i>Symphyotrichum campestre</i> have been described. Variety campestre has glabrous or sparsely strigose leaves and occurs in southern British Columbia, Colorado, Idaho, Montana, <i>Nevada</i>, Oregon, Washington, and Wyoming. Bloomer’s <i>Aster</i>, <i></i></i>var.<i><i> bloomeri</i>, has moderately strigose leaves and occurs in California, <i>Nevada</i>, and Oregon. The varieties are not sufficiently distinct to warrant recognition. <i>Symphyotrichum</i> ×columbianum (<i>Piper</i>) G. L. Nesom (syn. <i>Aster</i> columbianus <i>Piper</i>, A. multiflorus Aiton var. columbianus (<i>Piper</i>) S. F. Blake, Virgulus ×columbianus (<i>Piper</i>) Reveal & Keener) is the hybrid between <i>S. campestre</i> and <i>S. ericoides</i> subsp. pansum.</p>
