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.

There is disagreement as to the exact native range of this species; we use BONAP's cutoff; POWO reports it mostly limited to the tropical Americas but also native to Kentucky, in conflict with BONAP. This species may occasionally be used in bird seed blends, which can spread it to new locations, but it is also a weedy species that spreads readily on its own. It is able to survive in disturbed, anthropogenic habitats, which aids its spread. We mark new eastern populations expanded because they are relatively contiguous with the native range, whereas we mark western ones introduced because they are separated from the rest of the range by great distances.
