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.

Although the new populations in New York state and Arkansas are separated by some distance from the native range, we marked them as expanded because the eastern edge of this species' native range contains many isolated populations and the distances between these are similar to the differences to these new populations. This species is also native to Canada and Mexico; we have yet to build these portions of its map.
