Not sure what you are asking here. Do you want to root the cuttings?

Yes, I want to root the cuttings. I did cut some asters and sedum 'Autumn Fire' after work. I cut off the flowers, re-cut the stems when I got home, dipped them in rooting hormone, and stuck them in sandy potting soil. And put a clear bag over them. Peggy

Most sedums are easily rooted by taking a piece from the stem and putting it in the moist soil, either in the flower bed or a pot.

I'm not sure that you will have anything at all next Spring but let us know how that goes. I rooted some Aster cuttings in early summer and they grew really well-are in bloom right now in fact. I plan to root in a lot more next year too.
