Giant knotweed (Fallopia sachalinensis), Japanese knotweed's gigantic congener, just doesn't get the attention of its dimunitive cousin. So it was interesting to find a whole article focusing on giant knotweed, and even more interesting that it was written in Japan. The Japan Times published this article about the towering herb, discussing its propensity for invasiveness in the U.S. and Europe. The article also briefly touches on Japan's apparent lack of concern for environmental health.
