Sold as (but clearly not), garden mint seeds. The plant may not be native - but I would like to put a name to it! I've re-posted it with the fully-developed inflorescence.
No interactions present.
It has a look of a Clary (Salvia sp),but your plant has no hood , just a lip.
Apart from anything else, it doesn't seem to be either a mis-labelled culinary herb (smell too faint), or a popular garden plant (flowers not very "showy"). So I'm guessing it's a - for want of a better word - wildflower being passed off for something saleable.
Hence, I hoped that the iSpotters might be able to identify it.
