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 is occasionally planted in gardens, and can escape from cultivation. There is uncertainty as to its exact native range. BONAP reports the eastern portion of this species range, from Alabama eastward, as adventive. Weakley's FSUS reports it as native to the coastal plain north to SC, and introduced only in NC and the Piedmont. We report these populations as expanded because, regardless of where you draw the lines, new populations are contiguous with the native range.
