↑Summary

One of the most common and widespread goldenrods of northeastern North America. Inconsistencies in the reported range of this species reflect the fact that some authorities include the widely-distributed S. altissima as a subspecies whereas others treat it as a separate species. Even the USDA's own range maps reflect this inconsistency, sometimes on a state-by-state basis, reflecting different standards used in the data reported by different states.

BONAP has more consistent range maps for both species, reflecting the treatment of each as distinct species.
