Solidago curtisii

Curtis’ or Appalachian Goldenrod

Solidago curtisii Torr. & A. Gray is native to much of the Appalachian Mts in eastern North America.  Stems are erect and straight, not bent as in S. flexicaulis (Semple & Cook 2006 FNA).  Two varieties were recognized in FNA var. curtisii and var. flaccidifolia, which are now treated at the species level as Cronquist (1980) had done.
