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.

Notes

The populations now considered to be this species were formerly considered to be three separate species of the yellow pond-lily (Nuphar lutea). We recommend against using the common name "yellow pond-lily" because it most frequently refers to that species. The names "spatterdock", "broadleaf pond-lily", and "cow lily" are more often used to refer to this species, so we prefer them.
