Introduced

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 native to southern Mexico and the Tropical Americas; BONAP reports the Florida and North Carolina populations as adventive, which we report as introduced because they are separated from the native populations by a large gap in which this species currently does not occur. We have not yet built the portion of this species' range map in Mexico.
