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.


The reported range of this species on BONAP is extends less far west than the reported range from USDA; BONAP considers much of the USDA's reports of western portion of the range to consist of false reports. On the other hand, POWO does not recognize this as a proper species or even variety or subspecies, instead lumping it in with American black nightshade (Solanum americanum), along with other taxa distinguished by USDA and BONAP.

In general, the black-fruiting Solanum, in the "Solanum Section" of the genus, are both hard to distinguish from each other, but subject to a great deal of taxonomic disputes.

Here we have gone with BONAP's classification scheme and based our range map on theirs.
