For fun, I grew three Ussurian pears from seed. They're now 1 ft tall, and I'm wondering what I could do with them. Can I graft a northern-hardy, edible pear selection like Parker, Luscious or Seckel onto them? Since the parent trees are 30+ ft tall, would I end up with a tree of that size after grafting, or do the scionwood selections impart any dwarfing characteristics of their own?

Thanks!
