Common name: Spotted Dead Nettle 'White Nancy'
Family: Lamiaceae

How ironic, PoppySue! I was just talking to a customer about this same plant! She was telling me she had a plant with white flowers and white in the leaves, but I didn't seem to have it. It had really spread in her beds. After seeing my "Pink Pewter" lamium, she recognized it, and I had a "White Nancy" on my back table I had purchased from an Anchorage greenhouse this spring. So... your addition to the PDB was very timely!
