Initially, Horseweed may appear to be a tall, columnar goldenrod with hairy stems, and leaves that tend to angle upward from their bases. However, it dull inflorescence sets it apart. Upon close inspection, the tiny flowers have some resemblance to the more attractive flowers of the Erigeron spp. (Fleabanes), to which genus this plant was assigned in the past. Return
