Betonica officinalis, bishopswort?

Hello, after the very helpful responses to my last plant id question I was hoping someone could either confirm or let me know I’m completley wrong about this next id! After researching I believe it’s Betonica officinalis, bishops wort. It does say online it’s not common in Scotland which is where I am. 

I can see I’m going to be a regular visitor to these boards and the huge amount of great information. Thank you
