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 also native to eastern Canada; we have yet to build this portion of its map. Although it is not found in Mexico, there is a disparate native population in Honduras, outside the scope of our site.
