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 is a somewhat weedy species that is not widely cultivated, and seems to have spread eastward on its own, probably taking advantage of open habitats and humans moving soil and seeds unintentionally. There are scattered reports in Wisconsin and a few east and south of there, but this species becomes increasingly rare moving farther east and south. We mark the entire new range expanded because it is adjacent to the native range and shows a clear pattern of spread.
