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.

This species is cultivated in gardens, and can escape. Although it usually grows better in intact wild areas than disturbed habitats, it can occasionally survive in areas along railroads and fallow fields. As a result it has established east of its native range, in scattered populations, where it is common. We mark these populations expanded because they are relatively close to its native range, but they could perhaps be labeled introduced.
