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.

We found conflicting reports of whether this species is native to California; Calflora reports it as native whereas BONAP reports it adventive. If it is adventive, it is best classified as Expanded because its range in California is adjacent to its native range in Oregon and also not far from its native range in Arizona.


This species has been introduced in numerous places, including California, which is adjacent to its native range, and other places that are not, including Europe and Hawaii. It has many of the characteristics of species that have become invasive, but as of yet this species does not seem to be causing any negative environmental or economic effects.
