Wood Nettle (Laportea canadensis). One of the stinging nettles, so don’t touch it; but it is a very decorative plant in the deep woods, where its foamy eruptions of tiny flowers—sterile below, fertile at the top of the plant—make a curious and interesting sight. The large oval leaves with stinging hairs distinguish it from any other local nettles.
