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 widely used in landscaping and often escapes cultivation. It has established beyond its native range in the northeast; we mark these populations expanded because they are extensive and contiguous with its native range.
