This tentative map is based on our own research. It may have limited data on Canada and/or Mexico, and there is some subjectivity in our assignment of plants as introduced vs. expanded. Read more in this blog post.

This species is native to both East and West coasts, but has expanded inland in part due to spreading along roads and railroads. We marked it as Expanded and not introduced, even though its new populations are sporadic and separated by large gaps, because it seems to be spreading and colonizing new habitats on its own, and there is a consistent pattern of such expansion throughout most of the continent.
