Japanese Knotweed is an herbaceous shrub that is prohibited under Michigan Law. This perennial plant can grow from 3-10 feet high, has hollow stalks that are persistent through winter, and looks similar to bamboo. Stems have a fine, white coating that rubs off easily. In Michigan, it blooms in August/September, and the flowers are arranged in spikes near the end of the stem that are small, numerous, and a creamy white color. This invasive species is extremely difficult to eradicate. Treatment should happen in the Fall.
