KAMasud, thank's for the info. That big Jackmanii is still going to stay with the house, because I've got way too many other plants to move, and this one can easily be replaced, but it's nice to know that it's possible to move it, if needed. I don't have the four years it will take to get it ready anyway!
Sorry, but I can't help you with your question about cuttings on the wild clematis. I've only tried to get clematis cuttings to grow a few times, but failed. It sure wouldn't hurt to try though!
