Yes, you can start new plants from any part of the old one.

If not just about any little piece you put in the ground will root. I agree with Tarav about making well draining soil mix, I use extra perlite in my succulent pots. I have lots of this plant, they are easy to grow and have an attractive bloom. Good luck!
