Is this wood nettle?
This plant grew out of cow manure that I put in my new garden in KY. In early spring I saw a lot of seedlings of this plant that stung me when I planted veggie seeds.There are hairs on the stem. The leaves are opposite and seem to be bigger and rounder than stinging nettle. The flower is tiny white. The flower stalk seems to be longer and more straight (not dangling) than nettles that I have seen on photos online. Is this wood nettle or another kind of nettle? I would appreciate it if someone could positively ID this plant.
