I had some small leaves to grow into plants; was not even trying to propagate. Cuttings rooted too. BTW, plants seems to be somehow etiolated (incl. whatever you have in the background (possibly sedum-jelly bean?) - not the C. muscosa/lycopodioides, I can't see much of that). Are they receiving enough light?

Thank you. I believe the other one is corsican stonecrop, it flowered last year. The weather still isn’t completely sunny in Wyoming yet. Mostly cloudy in the afternoons. They get bright morning sun when it is sunny and I put them west facing in the afternoon if it’s still sunny. The stem of the main one pictured turned red after it was very sunny for a couple days.

I don't have any idea what zone is Wyoming. The plant doesn't look like mexican stonecrop - but photo is not clear enough to tell. It has needle-like leaves, and I think I see the rounded leaves. What were the flowers like?

If I am correct with ID of your plant, it should be much more compact. That means it needs more light. I am in z5 in Canada, and winter is long and there is very little sun. But growing succulents requires good light - so I use supplementary lights. In summer, plants go outside (they needs to be aclimatized to the direct sun). Here is a photo of my plants, they get reddish color in good light

Yes, I see you are right. I will go buy a grow light. Looking back to the pictures when I first got them, there is a difference in their appearance. They did not get enough light over the winter

If you have access to the outdoors, you could keep them there until late fall. If not, grow light will help. Either way, make sure you aclimate plants to better light.

I was wrong about the small plant; it is a sedum. Could be hardy Sedum album. It should be compact, and because it's hardy, it will overwinter outdoors.
