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.

This species is widely agreed to be native to the central US, but to have expanded beyond its original range. Different sources disagree as to the extent of its native range; BONAP considers it adventive in Illinois and Missouri, whereas POWO considers it native there. The easternmost populations are more likely to be transient and FSUS marks them as waifs. We treat it as expanded rather than introduced even though there is a large distance between some of these new populations and the native range, because it shows a clear pattern of expansion adjacent to its native range, and it seems to be spreading on its own. This species is also native to Mexico, but we have yet to build this portion of its map.
