Solidago latissimifolia Miller occurs in fresh and brackish swamps and thickets of the coastal plain near the Atlantic coast from Nova Scotia to Florida.  The common name is based on a long used binomial for the species S. elliottii Torrey & A. Gray; the Miller name has priority (Uttal and Porter 1988).  Involucres mostly 4–6 mm; broader phyllaries 0.7–1.2 mm wide; stems glabrous below arrays; mid cauline leaves elliptic ().  The species includes diploids (2n=18), tetraploids (2n=36), and hexaploids (2n=54).   Semple et al. (2021) published a cytogeographic map showing the locations of published counts.

Solidago latissimifolia could be confused with S. rugosa var. sphagnophila, but former usually has large elliptic leaves and smooth stems.
