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 parts of the central to southwestern US and south through Mexico into Central and South America. However, it has expanded its range due to humans introducing it to new areas. Different sources disagree as to where exactly it is native; we mark it Expanded in California since Calflora lists it as non-native, but native in Arizona, and native in Florida but expanded in most of the other eastern states. We have yet to build the portion of the map in Mexico.
