Question
Another large, many-branched (presumed) Persicaria. This is growing beside a paved path in Somerville, Massachusetts. The green strip beside the path has many non-native weedy to invasive plants.
Answer
Dear jfc, this is Persicaria pensylvanica (Pennsylvania smartweed). It is one of two species in the northeast that lacks a fringe of bristles at the summit of the stipules (the tubular sheaths at each node). This is a common species, frequent in moist to wet soils of New England.
