Amos Ziegler Posted September 9, 2016 Report Posted September 9, 2016 I received this request for identification help and thought I would ask the forum community for some assistance. What follows is part of the original message I received: Quote Hello, my name is Milton D. Hill Jr, I'm a resident of Shay Lake located in Dayton Township, Tuscola, County. I also test our lake/canal water for ecoli/bacteria. We have no problems. However, our man made canal is being taken over by a invasive plant. It looks and growslike grass, but has a small thin flower growing on top. It spreads like turf. I have looked at pics on your site and also reviewed pics of other invasive plants and have not been able to identify it. I am attaching a few photos Quote
ErinFuller Posted September 13, 2016 Report Posted September 13, 2016 Perhaps water-pepper (Persicaria hydropiper)? http://michiganflora.net/species.aspx?id=2282 If not that, I think it's related - some kind of smartweed (Polygonum spp or Persicaria spp). Quote
Kevin Walters Posted September 20, 2016 Report Posted September 20, 2016 Spotted ladysthumb (Polygonum persicaria)? http://plants.usda.gov/core/profile?symbol=POPE3 Quote
