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.
Our map is complete for the US and Canada but this species is also native to Mexico and we have not yet completed this portion of its map.
↑Notes
We recommend against the use of the misleading common name "nodding pogonia", as this species is not in the Pogonia genus by most authorities.
