Re: Leaf puzzle
That shrub looks more than this year's baby Carol, so does this happen every year?
Maybe something to do with the original grafting rootstock?
See if this helps:
" Sometimes grafted rootstocks can sucker and send out shoots that revert to the type of growth of the original tree. If these suckers are not cut off and removed, it can overtake the growth of the graft. ... Sometimes scion branches on grafted trees simply die, and the rootstock is free to regrow."
