Solidago flexicaulis A. A. Reznicek

Moist, rich forests, often in moist hollows, ravines, and banks; rocky (especially limestone) forests; shaded stream borders, swamps (cedar, ash).

Specimens of S. patula in which the one-sided nature of the inflorescence branches is obscure would key here (the leaf shape and angled stem are quite similar), but S. patula has very scabrous upper surfaces on the leaves, which are smooth in S. flexicaulis, and is clumping, not colonial from creeping rhizomes. The zigzag aspect of the stem seems to be more striking in the field than on pressed specimens. Rare collections with narrower and sometimes fully glabrous leaves may be hybrids, perhaps with S. gigantea.
