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.
Different sources report wildly different introduced ranges for this plant in North America; this may reflect different taxonomic schemes. We have not yet investigated this matter. Some sources, including USDA, report this species occurring in Canada; our map reflects BONAP's map and has only been built for the US.
