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.

POWO and several other sources report this species as not occurring anywhere in the US, only reaching to southern Mexico. We have not yet resolved the discrepancy between these sources and USDA and BONAP which report it in the southeastern US. Currently our range map is based on BONAP's.
