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 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.
