|discussion=<p><i>Symphyotrichum novae-angliae</i> is escaped from cultivation and introduced in Montana, Oregon, Utah, Washington, and Wyoming, and has been reported as an ephemeral escape in British Columbia. It possibly escaped from cultivation elsewhere. The Michaelmas daisy is widely sold in the horticultural trade, where cultivars have been developed. Forms have been described that correspond to color genetic variants within natural populations {<i>Aster</i> novae-angliae forma roseus (Desfontaines) Britton; A. novae-angliae forma geneseensis House}; they are not recognized here.</p><!--
--><p><i>Symphyotrichum novae-angliae</i> resembles <i>Canadanthus modestus</i>, but the ranges of the two do not overlap, and the latter has sparsely hairy cypselae with dark ribs. <i>Symphyotrichum novae-angliae</i> hybridizes with <i>S. ericoides</i>, forming the F1 intersectional hybrid <i>S. ×amethystinum</i>.</p>
