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.
↑Notes
The ERA data showed this plant also native to some regions in the southeastern U.S., but none of the sources we checked, including the USDA that the ERA supposed used as their source, cite this population so we assume it must be an error.
