Knotweed
Knotweed is NOT NATIVE to Sutton. It is fairly recently introduced - it is traced back to an arrival in Philadelphia, Pennsylvania in 1910. In those short years it spread all over the US and it is now a fairly invasive species in Massachusetts. In early September it creates beautiful blankets of pink-purple in the area.
Persicaria longiseta - also known as long-bristled smartweed.
