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 cultivated, and sometimes escapes cultivation. However, it is also expanding its range eastward along the gulf coast and southern portion of the east coast. It probably benefits from humans clearing land and creating more open, disturbed areas in which it thrives. We marked California, Illinois, and Connecticut populations introduced because they are separated from the rest of the range by great distances.


Although Coreopsis basalis (Otto & A.Dietr.) S.F.Blake and Coreopsis wrightii (A.Gray) H.M.Parker ex E.B.Sm. are listed as synonyms by POWO, and BONAP also treats them as a single species, the USDA maintained two separate pages on them. When we imported data from the ERA, we originally had separate records and maps, but we have since merged them and now treat them as one species.
