Oh, my! A great deal more information is needed. If you planted any seed in this pot, what did you or could you have planted? Where did the potting soil originate? (If it was a bag of sterile potting mix, or from a landscapers huge mound, or?) While I'm guessing these are all of the same plant, they aren't in order it seems? IMG_0257.JPG appears to be the latest. It's too young for me to have any idea.
