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 with wind-dispersed seeds, able to grow in disturbed habitats including lawns, roadsides, and waste areas. It has expanded north and east of its native range; our map is based on BONAP, but this species may have a broader expanded range than reported here. In the east, wool-combing mills have played a role in its spread.
