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 Mexico; POWO and FSUS both consider it introduced in Texas and Louisiana, although BONAP marks it as native in those states. Although some of the new populations of this species are separated from the rest of its range by long distances, we have marked all of its new range as "Expanded" because it shows a clear pattern of expansion adjacent to its native range, and it seems to be spreading on its own.
