Caryopteris Propagation

I do not tend to have much luck with stem cuttings...so I am hoping that if I take a couple of smallish Caryopteris I purchased recently, and repot them such that only their little branch tips are showing, they may root along each branch?

Has anyone tried this and if so, tips and tricks appreciated! I want to plant this out as it is so good for the honeybees, and gives them feed very late in the season when there is so little out there for them.

Regards,
Janet
