Japanese stiltgrass (Microstegium vimineum) is a non-native, invasive grass species originally from Asia. It was accidentally introduced to the United States in the early 1900s, likely through packing materials. This fast-growing grass spreads rapidly, forming dense mats that outcompete native plants and disrupt local ecosystems. One fun fact about Japanese stiltgrass is that it thrives in shady, disturbed areas such as forests and roadsides, making it especially tricky to control. Its name comes from its unique, slender stems that resemble stilts, allowing it to "walk" over other vegetation and spread efficiently.
