It's a retard. Hurry, cut it down, and use it to make a paste to paint your face and pray to the 'It doesn't matter' God. It really doesn't matter, at least it's growing something.
I know it sounds crazy, but it works. Also, dip the end of your pecker in peanut butter, that always works. In all seriousness, I don't think it's a problem, it just seems funny. Maybe you's got yourself one of them 'slow' plants.
