Description of specimen

Following the purchase of our home 3 yrs ago the tenant next door confirmed the plant was knotweed between our homes. We have periodically dug at new rhizomes but our efforts are not controlling the proliferation on the neighboring property. At time of writing there is a patch approx. 40 ft. in length, 6 feet in width and 10 - 15 feet in height.
