Grafting is possible if your bush is large enough and you have suitable rootstock but I prefer to propagate from seed. They grow quite easily but just take a few years to grow to any size.

thanks Bulbaholic Ill try from seeds

Hi, haven't seen you on here in a while. You can also propagate new plants from cuttings. These would be an exact clone of the parent plant. Seeds don't always come true, but you'll still get a few nice plants from seeds, some may even be nicer than the parent. To clone your plant from cuttings, go to this website for detailed instructions.
