Milkwort Knotweed (Polygonum polygaloides Wall. ex Meisn.)
POWO has merged other taxa into this one, including a much broader range of populations than those considered under this name by USDA and BONAP. We have not yet reviewed these merges, and for now our map reflects BONAP's treatment.

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 range map.
