Itchgrass (Rottboellia chochinchinensis), also referred to a raoulgrass, is an erect annual grass that reproduces by seed. Plants are pale-green in color, have short stiff hairs arising from the leaf sheath and leaf blade, and contain prop-roots near the base of the plant. The seed head is pencil-like and jointed. Mature plants may reach 10 feet in height.
