Over winter Gazania

I have bought this year as most years Gazania bout now with the prospect of the new greenhouse and using the conservatory as a stand by greenhouse I was just thinking can I over winter these plants also how would you propagate this plant.

While I'm on the subject of propagation the link for taking cuttings from violets is broken

Would someone please explain how to take a cutting from this plant please?

Gazania can you propagate by root cutting??

Looking forward to your replies
