CommentsThis woodland goldenrod has a terminal inflorescence that is rather lanky and spreading, while its lower leaves are lanceolate-ovate and coarsely serrated (superficially resembling the leaves of American Elm, but more narrow and thin-textured). Elm-Leaved Goldenrod is similar in appearance to Canada Goldenrod (Solidago canadensis), but the latter has lower leaves with 3 parallel veins (a central vein and two lateral veins). Canada Goldenrod also has more hairy leaves and stems, and the major branches of its panicles are usually less divergent than those of Elm-Leaved Goldenrod. Other goldenrods (Solidago spp.) can be distinguished by some combination of characteristics involving the appearance of their leaves, stems, or inflorescences. Because there are many goldenrod species in Illinois, they can be difficult to distinguish.
