Acuba Japonica?? Propagation Hints??

Hey Kids..
I have a couple varieties of Acuba and they thrive for me even though they are Supposed to be borderline hardy here in Z6.
Softwood, Semi-soft, or hard wood?? Should I cut out the terminal node of each cutting and cut or remove the larger leaves?? Glass of water or rooting hormone in a soil less mix??
I'm just a putz but if I can get 30% out of any propagation attempt I am happy.:smile:

Ps.. I'm betting I will have tried it prior to geting a response but such is life. Now back to spreading MULCH!!! ARG!!!!:mad:
TY in advance my dirty friends.
