Landscape: An arching yellow addition to your shaded meadow garden or woodland.

Comments: Blue-stemmed goldenrod differs from zigzag goldenrod in that the zigzag goldenrod has wider leaves that are coarsely toothed and petiolated.  If you see the blue-purplish stem, it is most likely the blue-stemmed goldenrod.   

Etymology: The epithet name caesia comes from the Latin word, caesius, meaning "bluish-grey" due to the bluish stem color.  The genus, solidago, comes from the Latin word, solida meaning "whole" and ago meanining "to make".
