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.

We marked new populations of this species in the interior west as expanded rather than introduced because it is a weedy plant that tends to spread on its own rather than being intentionally planted, and because these new populations are not far from portions of its native range.
