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.

Some sources show this species as also native to Utah and Wyoming; we follow BONAP's treatment which says it does not occur there and never did. This species is also native to Mexico; we have yet to build this portion of its map.
