Subspecies 2 (2 in the flora).
Solidago sempervirens is common along the seacoast from the Gulf of St. Lawrence to central America and the northern West Indies. Introduced populations are sometimes very large near the Detroit River and Lake Erie in southwestern Ontario, eastern Michigan, and adjacent Ohio. A second disjunct group of populations occurs in Illinois and Indiana in the Chicago area at the southern end of Lake Michigan. Two mostly geographically separate subspecies can be recognized in the flora range. A race also occurs in the Azores and is undoubtedly introduced there [Solidago sempervirens var. azorica (Hochstetter ex Seubert) H. St. John]. Plants cultivated in European gardens have been labeled S. sempervirens var. viminea (Aiton) A. Gray.
