Jose - honestly I am unsure. There is not even an Oakleaf Superba in Moose Land. We need to defer to those who could give you a more definitive opinion. It's a very, very nice looking croton regardless of it's name.
Dean - could you move this thread to the Croton Forum? I believe that is where Jose may have intended it to be posted.
Wow, nice plant, but I was told by someone I can't remember that this was an Oakleaf Superba. Mmmmmmmm, different leaf shapes. Yours has kinda of a Geisha Girl shape.
