You can take 6 inch basal cuttings of ripened wood in Sept/Oct and root in a cold frame or with some protection. They should be ready for potting on in the early summer. Keep them in pots for the first 2 year and overwinter under glass. As you can see it can be done but takes a while.
I don't know about cuttings but I often get seedlings in my garden which can be dug up and potted on.
that's interesting. Mine flowers every year and I've never seen a seed yet, I thought maybe it need a warmer climate to set seed. I do get some suckers though, if I want some new plants
