Invasive Plants of Oklahoma
Maps for confirmed county distributions in Oklahoma are by Oklahoma Biological Survey and should be considered works in progress.
Also known as Japanese grass, it has short, flat leaves, generously gapped and alternately arranged along stem that gives the appearance of very thin cane except for the leaf sheaths. Low branches can be root at nodes spreading the plants rapidly.
