i know this has been discussed before, but I though I would bring it up, since I have lovely new growth pictures. I have read previous topics where it seems to be the consensus that Prom Queen is probably Prosperity. Does this photo help? it is new growth from near the base and is about 8' long (pretty good since it was small stick when I planted it this spring) The new growth is a gorgeous red with large, sharp thorns about every 2cm.
