Solidago chapmanii A. Gray is native to sandy soils at the margins of open pine and oak woods mostly in Peninsula Florida. The stems are short-hairy entirely or in lines or strips running down from supper stem leaf bases (Semple & Cook 2006 FNA). The species is diploid 2n=18.
The species was treated as S. odora ssp. chapmanii (A. Gray) Semple in FNA (Semple & Cook 2006 FNA). Plants can be similar to S. fistulosa or broader leaved S. odora. In a multivariate study of S. subsect. Venosae, S. chapmanii separated well from S. odora and more so from S. fistulosa (Semple, Bzovsky, & Tong 2016).
