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 only rarely cultivated in gardens, but it is somewhat weedy and can escape cultivation; it can grow along roadsides and railroads, and humans have created more habitat for it in the east by clearing land. Although the northeastern populations are mostly established from garden escapes, we mark it as expanded because it seems to be fairly predictably expanding east of its native range, with more introductions closer to its range, and the new range is relatively well-connected, separated only by distances not much longer than exist in its native range.

Notes

Both BONAP and POWO list Mirabilis albida (Walter) Heimerl and Mirabilis hirsuta (Pursh) MacMill. as synonyms of the same taxon. However, the USDA lists them separately and reports separate maps for them. We have not been able to explain or reconcile these differences.
