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 somewhat weedy, able to survive in anthropogenic habitats such as roadside ditches, which has probably contributed to it expanding slightly at the northeastern limits of its range.
