The leaves are similar to those of S. rugosa except they usually taper abruptly to a short petiole. In addition, S. rugosa is rhizomatous with hairy stems and heads with 6-12 ray flowers. Solidago arguta is another similar species but has leaves that are glabrous on the lower surface, lower leaves that are usually more rounded (like S. flexicaulis), heads with 8-20 disk flowers, and glabrous fruit (cypselae).
