About Japanese Stilt Grass

Japanese stilt grass is an annual grass that is generally 1-3’ tall but will also spread in a mat-like manner. The stems are hairless and branched with upward pointing tips. Japanese stilt grass can spread vegetatively by rooting at the nodes as well as by seed. It prefers wetlands, streambanks, ditches, mesic forests, floodplains where its large seed bank can be spread by moving water. It out-competes native plants in low light conditions.
