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 is a weedy plant that spreads prolifically. It can survive in disturbed anthropogenic habitats including abandoned fields, waste areas, and along roads and railroads. Taking advantage of human activity, it has spread on its own into some areas northeast of its native range, but it is uncommon and sporadic in much of this new range.
