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.

BONAP reports this species as adventive in Wisconsin, but most other sources note it native. We marked it as expanded because this region is contiguous with its native range. However we note that it is uncommon and scattered in this part of its range.
