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.

We mark the Arkansas populations introduced because they originate as garden escapes and are mostly disconnected from this species native range, but we mark a few other populations as expanded because they are contiguous with the native range.
