In your zone I would wait for spring planting. Here is growing info if you have not yet read it: https://www.gardeningknowhow.com/ornamental/cacti-succulents/sedum/sedums-plants.htm
As for being resistant to deer, yes, for the most part they are. However, that said, you should be aware that being deer proof is something altogether different. No plant is 100% deer proof as they will eat anything if hungry enough.
We just moved to San Antonio, TX and need flowers that can grow in this full sun heat. I read your article about the Sedum, and it sounds good. We have rocks and boulders around our yard and also an old wash pot that we would like to put a pot in with flowers.
The plants in this article may also perform well, just remember to give more water to the ones growing in pots: https://www.gardeningknowhow.com/ornamental/flowers/fgen/full-sun-plants.htm
Oh, yes, sedum should perform very well. Most succulents would do nicely.
I have a sedum plant and crassula plant in containers outside my front door. The weather has been really cold and freezing, and I noticed on Sunday that both my plants had frozen entirely and the leaves and main body of the plant had drooped, looking like they had both died! I have now brought them inside and don't know what to do with them. Do I leave them alone or cut back? Will they recover on their own and should I leave them inside until the weather improves? I live in North Wales and the temperatures overnight have been minus ten degrees Celsius. I completely forgot about them and just thought they would be okay, as I have read that they are very hardy. Any help or advice would be much appreciated.
I am sorry to hear about your plants. If the stems are still alive, they will regrow their leaves. I would check the stems and if they are still alive, care for the plant as you normally would and you should see leaves start to grow in a few weeks.

How do I transplant a Sweet Autumn sedum?

How do I care for or prune my potted sedum plants?
Sedums need very little care. In fact, most potted sedums are killed by over care rather than under care. Really, all they need is proper watering. Water only when the soil is dry.
As for pruning, most sedums do not need pruning, but if yours is getting unruly, you can simply cut off unwanted growth with a sharp, clean pair of scissors.
What is the name of a succulent that looks like creeping jenny but has the leaves of succulent plant?
Many succulents of the genus sedum could fit the bill. Here is one for "creeping blue sedum" that has leaves very similar to creeping jenny:
I purchased about 40 'plants' online. They arrived more as 2-3" roots. I did not get specific instructions on how to plant. I made the bad assumption, I guess, that I needed to plant them about 1" deep. Only one ever came up. I've got replacement 'plants' and when they arrived, I researched more thoroughly and came upon this website. It was the only one that explained I should more or less 'lay them' on top of the soil, or under a fine layer of dirt. My question is, how much water until established? As they are succulents, they shouldn't require extra watering once established (other than natural rain in our area). I don't want to under/over water these new starts. Thank you!
Generally, watering for the first couple weeks should be sufficient time for the roots to establish. The, water only when the soil is dry.
