Here is a container I planted with Sempervivum and Sedum a few years ago. It thrives with almost no care, can dry out without problems, and doesn't mind winter or summer.
I decided to plant this strawberry pot with similar starts from around the yards.
The sedums are cuttings. Just cut pieces from existing plants and poke them into the soil. They root quickly with no other effort. I do cut off the growing tips so they will branch and fill in. Sempervivums are splits from my original plant. They don't have many roots but will establish just fine. There are a couple more pockets to plant, plus a second strawberry pot.
