I have been trying to propagate this plant for 4 years with no success. Has anyone had success propagating this plant?
I have never propagated it, but....two suggestions.
1) Have you tried heel cuttings dipped in rooting hormone?
2. Search this Forum for the postings I have done titled "Toothpick technique". August is the month to initiate the first part of this rooting method and it really does work on difficult to root woody plants. Easy to do.
Here is a link that might be useful: Toothpick
