|discussion=<p>Widely cultivated for aromatic oils, <i>Artemisia annua</i> often persists in gardens, becoming naturalized in moist-temperate areas (especially in eastern United States). Reports of naturalization may be exaggerated (reported for Prince Edward Island, but not established).</p><!--
--><p>The systematic placement of this species appears to align most closely with species of the Eurasian subg. Seriphidium (L. E. Watson et al. 2002). Molecular evidence suggests that the <i>Artemisia annua</i> lineage may be ancestral to woody species in the Old World.</p>
