Weed or Volunteer Narive Plant - 2018 Edition

[greenthumbomaha]

I may have planted this one last summer in my herb bed as it is front and center in a large planter. Pay no attention to the sorrel going to seed leaning on the left side of this monster.


Next am I coddling a privet or a weed? The new growth is a very brite greenish yellow, about 3 feet tall in total.


This has square stems. Is this thug growing all over different beds a weed, monarda that is spreading wildly with the rainy weather, or some speedwell that is blooming much later than other varieties, or ???


The grey plant was from a plant exchange. I was told it was invasive, but didn't expect this much so soon. I don't recall the name but would like to know what it is.
