Horsetail, field, (Equisetum arvense) and Scouringrush (Equisetum hyemale)

Plants resembling grasses

Field horsetail

Perennials with spreading rhizome systems that are often mistaken for a grass. Field horsetail (photos 1 and 2) is unique with two types of stems. The fertile stems that appear in the early spring are unbranched, with "cones" at their ends. Nonfertile vegetative stems appear later in the season, are highly branched (8 to 12 inches tall), and resemble a horse's tail. Scouringrush (photo 3) is found exclusively in ditchbanks and other wet areas and has jointed stems (2 to 3 feet tall) without branches.
