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 plant is widely cultivated and frequently escapes cultivation in some areas; northeasternmost populations were established by such escapes, but we have marked them as expanded because they are adjacent to the native range.
