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 aquatic plant is sometimes cultivated, and readily spreads into the wild, leading it to establish at a few sites slightly north and inland of its native range; we mark the new range as expanded because it is relatively close to the native range, and because they occur in a broader region where there are a few native inland populations as well.
