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.

In this plant's expanded range, there is only one isolated population reported in West Virginia; we marked it as expanded because it is near its native range, and because it is a weedy plant that is not usually cultivated.
