Discussion

Members of the Artemisia ludoviciana complex with deeply lobed leaves are sometimes confused with A. michauxiana, and there is evidence that plants hybridize in some locations. Artemisia michauxiana is distinguished by its glabrous, bright green to yellow-green foliage and lemony-sweet fragrance.
