White Dead-nettle (Lamium album) is a common wayside weed/wildflower in both town and country. Even so it seems to be especially prolific this year.
 Like other "Dead-nettles" in the Lamium family the leaves resemble Stinging Nettles but do not sting. L. album in particular seems to like growing among them, which is perhaps an evolutionary survival strategy. Lamiums are top bee plants and White Dead-nettle has clam-like flowers which bumblebees shoulder open with great determination.
 A friend of mine who grew up in the Scunthorpe area in the fifties and sixties tells me that children would pluck the flowers and suck them to get a small hit of nectar.
