Expert Response
Yes, it most likely is purple loosestrife. The square stem is a good indication. Here is a link from the DNR with suggestions on how to control it. One note, similar to quack grass, any small amount of roots left in the soil will produce a new plant. https://www.dnr.state.mn.us/invasives/aquaticplants/purpleloosestrife/control.html
another Master Gardener has suggested it might be this plant: https://www.minnesotawildflowers.info/flower/showy-tick-trefoil
