Bev, I know what you mean! I wondered why this one was assembled of plants with different needs, because it seemed it could so easily be done otherwise.
Here are some pictures of how I dealt with the different plants:
This container will live inside this winter: You can't really see but the jellybeans are mostly in here. Some of them I stuck here and there outside too, just to see how they fare:
This is the one you think is likely Sedum makinoi, and it's in a pot sunk in the ground, next to a couple other sedums I am not sure where they will go next season. Some I also put in the dish that will live inside, just for looks:
And these are the semps and a sedum that were in there, which I am pretty sure are hardy; I plunked them right into the ground:
Fingers crossed!
The one in the dish, that is budded out and which you had no idea what it is, (it's on the right in the picture) sadly some of its stems are mushy, and I don't know why! because the soil in the original container was bone dry to the bottom. Anyway, I laid them in under some potting mix in hope they'll somehow recover or at least last long enough I can see the blooms.
