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 occasionally grown in gardens, and self-seeds and spreads into the wild readily, where it thrives in disturbed, anthropogenic habitats, including overgrazed pastures, fallow fields, and areas along roads and railroads. As a result it has established both east and west of its native range. We mark both new portions of the range expanded because the new populations are mostly contiguous with to the native range with only small gaps.
