Jelinda, I agree with Lori.
I am in zone 8 also, in a very wet climate this time of year and through most of spring. My sedum do the same thing as what you are showing in your photos. Most of the time they just site there in a semi-dormant state until spring, for me at least.
This year seems also to be through us a curve ball in the weather department, tricking some plants into thinking spring is arriving. Even my pineapple guave is sending new bloom and fruit set the beginning of Nov.
Lori is correct about the drainage, just make sure the water has a place to go and doesn't fill up the containers, or form ponds around the plants that are in the ground. They should be fine.
