Discussion Japanese Stiltgrass, also called Nepalese Browntop, was probably accidentally introduced into the United States when it was used as a packing material for porcelain products shipped from China. It is considered an invasive or noxious weed in many parts of the East. This grass can form dense colonies in forest understories to the exclusion of other, native plants. Seeds can remain viable in the soil for at least three years, which makes removal of an infestation a long-term process.
