the quickest way to get may plants is to use seed.or division.
The flower stalk often will not root but can try

Years ago, I sent away for twelve different kinds of "Hen & Chicks" Some of them looked almost exactly alike, so I took the time to label them correctly, etc. The next day, my pet goose pulled them up and took them to my fish pond and had a ball with them. She damaged them so badly that I couldn't plant them in that condition. So I pulled off the leaves that weren't too badly damaged and planted them in sand and peat combination. Almost every one of them survived. I then had a LOT of plants, but didn't know their names!!
