Description of specimen

Plants about 18 inches to 2 feet. Looks just like specimen photographed in The Dalles Chronicle of 8/27/16 in an article about knotweed. Tough stems. Leaves about 1 1/2 to 2 inches long; clusters of flower buds present but not opened yet. Pulled a plant and it was very tough to get out.
