Solidago tortifolia

Twist-leaf goldenrod

Solidago tortifolia Elliott is native to dry, usually sandy soils in pinelands and embankments on the coastal plain of the southeastern U.S.  It has linear to linear-lanceolate leaves that are reduced upward and lower leaves that often twist into coils when senesced but persist on the stem (). Unlike the closely related S. juliaeÌý²¹²Ô»åÌýS. leavenworthii, which have elongated narrow secund pyramidal inflorescences, the inflorescence of S. tortifolia can be broadly pyramidal with more elongated lower branches. In a multivariate study of possible related species, S. tortifolia was the most strongly supported species statistically (Semple & Lopez Laphitz 2016). The species is diploid (2n=18). Semple (2023) presented the cytogeography of the species.
