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.
This plant is widely cultivated as a food plant and sometimes ornamental. They have widely escaped cultivation and established a broader range which we mark expanded in the east as it is contiguous with its native range. We mark some western populations introduced because they are more geographically isolated. However there is some subjectivity and western populations could perhaps also be marked expanded.
