looks like cross between garlic mustard and lamium?

Found in sunny opening in rocky woods of northern VA. Most likely a weed...square stem basal rosette of scalloped leaves...looks a bit like smaller lamium or garlic mustard but leaves are very big....seed heads on stem were similar in position to Lycopus...so around stem. I can take picture of seed heads but they look like clusters of typical mint seeds...no scent to crushed leaves.

Thank-you for any suggestions.

Motherwort, Leonurus cardiaca, is very close but leaves are more rounded...seed heads are very similar.
