From what I know about them, they form their thick trunk quickly and some times stem cuttings don't. However, type and flower color is mostly drab. They use seedlings to graft special kinds onto. It is very hit and miss, mostly miss to obtain a nice specimen. But knowing this, your chances are good to get one great one for every 8 normal ones. If you can grow a large amount of them, wait two to three years to see what you have, them have a buyer for the baulk for grafting stock. You will come out a winner. Grafting is one area I just can't seem to do. My touch seems to kill them. I have been showed and have tried many times only to fail each time.
