An aggressive annual weed originally from Asia, Japanese Stilgrass could be one of the most invading species in moist areas.
Japanese Stiltgrass grows up to 40 inches (100 cm) tall and has a cool silver stripe on its leaves. It's shallow-rooted and has aerial rootlets. It flowers in late summer, and its seeds look like caryopses. You can usually find it growing next to White Cutgrass. Its leaves are arranged alternately on thin, branching stems, giving it a bamboo-like appearance. The seedheads are pretty small and contain small, elliptical seeds with twisted awns.
