I think I got them in 2010 from my aunt.
I probably do not notice if it likes being moist in winter since I have it outdoors and we get the rain at the same time. But pretty much my typical rule with my succulents I try not to water them in winter if possible. But hard to avoid when it rains here. My understanding was they are supposed to be dormant in winter, but here they just get chilled and occasionally rained upon, so they get that reddish color hues. So next option is to keep their media really fast draining and plant them shallow, so if it does rain the water drains out fast.
Cold and dry okay, but cold and wet will be bad..so be careful when you keep them moist during winter.
