Expanded or Not Present

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 widely agreed-upon to be native to Mexico, and to have expanded its range into the US. We mark the entire new range Expanded because it is largely connected and separated from the native range only by small gaps not appreciably larger than those found within its native range. BONAP and Go Botany mark it as native to California, but Calflora, which we defer to for local considerations, considers it non-native. We do not know exactly where the original native range of this species ended, but for now our map (rather arbitrarily) considers the US-Mexico border the cutoff. We have yet to build the portion of this species' map in Mexico.
