Discussion

Artemisia serrata is closely related to A. ludoviciana and A. longifolia; it is distinguished by its prominent, serrated leaf margins. It is apparently native to the upper Mississippi Valley and naturalized in New York, presumably following introduction as a garden plant. Reports from Kansas and Missouri may be based on collections of A. ludoviciana.
