My mystery plant has been potted and seems to be doing great. I dug the thing up, flopped some garden dirt right on top of it and placed it with my other plants in my back yard. I was fine with it until I was informed that it is a weed, now I love it even more! I have no clue what kind of plant it is but it has tiny yellow flowers on it that last for the longest time before wilting.
Any ways the definition of a weed is "any plant that is not wanted" so, with that said what I have is not a weed.
