Solidago leavenworthii Torr. & A. Gray is native to wet soils, thickets, edges of bogs, and wet prairies on the coastal plain from North Carolina to Florida.  The mid to upper stem leaves are finely serrate with 1-10 teeth, the largest 0.25–0.5 mm long ().  Plants can be similar to S. tortifolia and has the fine stem pubescence of the Tortifolia group of species.  The species includes tetraploids (2n=36) and hexaploids (2n=54), while S. tortifolia includes only diploids (2n=18).  Semple (2023) presented the cytogeography of S. leavenworthii.

Inventor Thomas Edison had experimentally bred plants of the species grown in Florida for rubber (;Ìý).
