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.

BONAP reports more populations as adventive than FSUS; for now we follow BONAP's scheme and mark Midwestern and Virginia populations as Expanded, not Introduced, since they are nearly adjacent to the native range, separated only by short distances. This species is also native to Mexico and Canada; we have yet to build these portions of its map.
