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 this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.

This species may also be native to Canada and Mexico although we have found conflicting evidence on its presence in Canada in different sources. We have yet to build either of these portions of its range map.
