Not the easiest plant in the world to strike from cuttings :-) In fact, this method of propagation is not highly recommended. Layering would be a much better option if you are up for that but if you really want to try, this article is an excellent how-to. And yes, it's a bit late....softwood cuttings are preferred.

Lilyfinch, I have rooted many. Just take a cutting, put in pine bark fines, wet, place in dappled shade and wait. I was surprised at how easy it is. I did softwood and hardwood. Now, we are in a hot humid zone and I am sure that really helps things. I don't know if I would do them now. Did mine over the summer.
