Description of specimen

Some sort of Knotweed, think it's Japanese, is billowing into pedestrian walkway behind property owner's fences. Bamboo-like nodes, alternating zig-zag leaf pattern, red stems. Lots of plants.

Commentary

Hey, David. Sorry for the delay in getting back to you. That's certainly knotweed, and that patch will be mapped. Feel free to reach me directly (mitch.bixby@portlandoregon.gov) if you want to know more about management strategies or any other aspect of this crazy plant.
