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 species was formerly widely cultivated in gardens, but in recent years it has not been as widely grown. As a result of its former widespread planting, it has established in the wild east of its native range; we mark the new range as expanded because it is close to the native range, separated only by short distances not any longer than exist in its native range.
