Help!!!

Invasive Plant –Japanese Knotweed ( Polygonum cuspidatum) is blooming profusely in Maine (and 36 other states) in September and actually looking attractive enough to cause a man to inquire if I sold the plant so he could take it back to Ohio. There are many websites to get info from.  Just don’t give our non invasive, clumping Bamboos a bad name by mistaking it for this terrorist creeper whose rhizomes can run up to 60 feet!
