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.
↑Uses
This species is widely planted as an ornamental, but has high invasive potential, particularly in the southeastern US. It has established robust populations from Arkansas east to Virginia, north to Kentucky and south to Alabama and Mississippi, and it likely has potential to colonize areas beyond this range.
We recommend against planting it anywhere in North America and recommend removing it ASAP.
