White dead-nettle (Lamium album) has hairy, toothed leaves like all nettles I know of. It doesn’t sting, unlike other nettles.
The dead-nettle leaves in the photo are the small ones around the flower. The big leaves in the photo are from a different plant.
If you were to carefully pull off one of the white flowers and suck gently on the tubular opening at the base of the flower, you’ll enjoy a puff of a sweet aromatic taste.
