Solidago canadensis var. hargeri

Harger's Canada Goldenrod

Solidago canadensis var. hargeri Fernald is distinguished by its lower to mid stems being moderately hairy (Semple & Cook 2006 FNA). The variety could be confused with S. altissima.  Semple et al. (2015) noted the difficulties in distinguishing var. hargeri and diploid S. altissima var. gilvocanescens.

Solidago canadensis var. hargeri is naturalized in western Europe.
