Here is the uncropped image of this plant...
This is Solidago uliginosa (Bog Goldenrod), growing amongst Equisetum arvense, Aster umbellatus, Calamagrostis canadensis, Rubus pubescens, Polygonum sagittatum, and others. Justin suggested the possibility of Solidago speciosa, which as he noted grows in drier conditions. Solidago uliginosa has thicker textured leaves that have a longer length to width ratio than those of S. speciosa. The lower leaves of S. uliginosa are somewhat clasping the stem, but this character isn't obvious in the quiz photo.
Solidago uliginosa is a polymorphic species of eastern North America, where it grows in bogs, marshes, and wet woods (Semple & Cook 2006). These photographs were taken on August 18, 2009 in Superior, Wisconsin. Plants of this species that we saw in Wisconsin look somewhat different from those that I typically see in Indiana. In fact, the first time I saw it, I had to ask our local expert which Solidago it was. Individuals of this species that I see in northern Indiana have fewer stem leaves and inflorescences that are less dense.
Solidago is from the Latin solido, meaning “to make whole or heal,” a reference to the medicinal qualities of the genus; the specific epithet uliginosa means “of marshes (Wisplants 2010).
