I mentioned Lamium galeobdolon in a recent post [3rd. April] and also Lamium maculatum a couple of weeks ago [26th. March]. Lamiums are characterized by square stems and double lipped flowers. The two just mentioned have clam-like flowers which are typical of a number of species in the genus.

 Bumblebees stick their snouts between the "jaws" of the flower to get at the nectar and pollen. The smaller bumblebees fit in quite easily but the larger bumblebees will not be deterred...

 White Dead Nettle (Lamium album) is a prolific weed/wildflower from spring onward which is good news for bees.
