    Here's a close up of what I think is Lady's Thumb? Taken roadside, wetlands woodlands, Windham, NH.

    Answer

    tracyd123, sorry, I cannot confirm this with confidence. Your image could be of Persicaria longiseta (Oriental lady’s-thumb smartweed). To tell what species you have for sure, I would need a close-up image of the tubular sheath found at each node (which will have a ring of bristles at the summit). Best wishes.
