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 species is sometimes cultivated in gardens, and can escape into the wild, in part due to the help of birds and small mammals spreading its seeds. Such introductions have led it to establish in new areas east of its range. It has also increased in some areas where it is native, due to overbrowsing in rangeland, which favors it over other plants. We marked the new parts of the range expanded because it is relatively contiguous with the native range, separated only by distances no longer than those that exist within its native range.
