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 British Columbia; we have not yet built the portion of its range map in Canada. It is also native to east Asia, outside the scope of our site.
