Black spot usually means it is Persicaria decipiens. However the habit and stem appearance look like Persicaria lapathifolia. Photos of the ochrea (at node where stem an leaf) are a big help when ID Persicaria.

Photo 2 shows ocrea, but is not good enough to show whether cilia are present or not.

Can you believe it? I went back for a better picture and the area had been mowed. No sign of the plant.
