Japanese Knotweed is a perennial plant native to East Asia, known for its rapid growth and invasive nature. It can reach heights of up to 10 feet and has hollow stems resembling bamboo. The plant produces small white flowers in late summer and has broad, heart-shaped leaves. This species is often found in disturbed areas, such as riverbanks and urban environments, where it can outcompete native plants. Due to its aggressive growth, Japanese Knotweed can cause structural damage to buildings and infrastructure, making it a concern for homeowners and property developers.
