I topped it due to leaf being directly on top of the main stem like all one in piece, maybe trinodal is the wrong word but it was really weird, so i just cut it off, nothing could have grown from it, by topping it the branches from below took over, didnt really have a choice to be honest. I would probably not touch if you dont have too, I do like to defoliate a bit here and there though.
I think mine is called a "trifoliate" or something.
I hope it grows out nice.. it was the only one out of three to germ.
