Welcome Shaw.
Here is what I found on Autumn Joy.
I realize I am late at this picnic but had to add my 2cents.
Your plants look great BTW.
"Sedum prefer full sun and average to poor well-drained soil. Can be divided in spring. No need to deadhead during the growing season. Cut back in early spring, as new growth will come from the ground, first appearing as little nuggets pushing up through the soil. Pinch back once during early summer if height control is desired. "
I see leaf cuttings here as a propogation method
