Swamp Rose (Rosa palustris Marshall)
Also classified as Rosa obtusiuscula Rydb.
Per POWO's treatment, we consider the "Appalachian valley rose" Rosa obtusiuscula to belong to this species; some authorities including USDA PLANTS, BONAP, and NSE, treat it as a separate species but mark it as "taxonomically questionable". Whatever choice is made has little relevance as there is only a single record with that name and it has been little studied since.

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 also native to Canada but we have yet to build this portion of its map.
