BTW two different 'square stem' pics? The first one could be Agastache or Motherwort (Leonuris cardiaca?) or a Speedwell (although not similar to any I know of here, there are a lot of different kinds). All of which have a flower spike which could look similar to the unflowered one in the first square stem pic.
The plant with deeply lobed leaves.. is not any of the labiatiae that I know personally, doesn't look like the same one you pictured first.
