Japanese Knotweed

Japanese knotweed (Fallopia japonica) is an invasive plant species known for its aggressive growth and ability to damage infrastructure. It thrives in a variety of soils and can tolerate poor growing conditions. Leaves are heart or spade-shaped with a pointed tip, arranged in a zigzag pattern along the stem. Stems are bamboo-like, hollow, and segmented. Appearing in late summer, the flowers are small, white or cream-colored. Its roots penetrate deep into the ground and form clumps of roots called rhizome that store massive amounts of energy making it very difficult to kill.
