Wood sage

Teucrium scorodonia - possibly! This wildflower was about 50 cms tall and growing in a fairly shady spot along the lane. It has a square stem, is a little bit downy and has no particular smell. I am a bit foxed and my sister the botanist is away on a field trip...
Any alternative suggestions? ?
Not a lot new down there atm but still a lovely place for a walk. :)
