Knotweed (Polygonum aviculare) is a very common plant in mowed areas. It grows where it does because it survives mowing and it can grow where the ground has been compacted by people walking on it. This knotweed is at the corner of River Road and State St. in West Lafayette, at the entrance to the Levee area. Picture taken August 2, 2009.
