Introduced 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.

Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.

POWO reports this species as also introduced in Southern Mexico, discontiguously with its introduction in the US; we have yet to build the portion of its range map in Mexico.
