Distinguishing Carpgrass from Stiltgrass

Most people are familiar with Japanese stiltgrass (Microstegium vimineum), the now ubiquitous annual grass that forms dense pastures of green in the shade of forests, and thrives in miniature in lawns.

Less common, confined to wet areas, is an invasive look-alike called carpgrass (Arthraxon hispidus). The curly edges of the leaves give it away. Google "carp grass" and you end up with links to information on grass carps, an Asian fish brought to the U.S. to control invasive aquatic plants.
