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 has bouyant seeds and can spread over open ocean, which likely is how it colonized its current range in the US. We found conflicting reports of exactly where this species is native; it is agreed to be native somewhere in Central America. BONAP reports it as adventive everywhere it occurs in the US. As such we marked its entire range either Native or Expanded. It is also found in Mexico discontiguously with its range in the US, but we have yet to build this portion of its map. The US population may have originated from Cuba and/or the Bahamas, colonizing South Florida and spreading from there.
