I am in Canada, bought an herb that I can't identify. See photos. I thought originally it was scullcap but it is not.
low growing perennial herb with halberd shaped leaf
I would suggest posting your question in the Plant Identification forum--you will get more & faster responses there (this forum is specifically for questions about the Plant Files database so many of the ID experts may not follow it).
