Expanded or Not Present

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 native to Mexico but is now found in south Texas and Florida, with isolated populations in coastal Alabama and South Carolina. We mark some of the new populations introduced because they are separated from the native range, but this was a subjective judgment call and these populations could probably be marked Expanded as well. We have not yet built the portion of its map in Mexico.
