Solidago gigantea A. A. Reznicek

Dry or usually moist open ground, roadsides, fields, thickets; prairies, fens, wet meadows, tamarack swamps, marshes; swamps, along streams and rivers; deciduous forests and borders.

This species resembles S. canadensis and S. altissima but has a glabrous stem, while the inflorescence is ± densely pubescent. The stem is often glaucous. The leaves range from glabrous to pubescent, and the uppermost ones tend to be more elliptic and toothed than in S. juncea. Furthermore, the lower leaves in S. gigantea are smaller than the middle ones, rather than distinctly larger as in S. juncea.
