Hi Marilyn. So sorry if I disrupted your genealogy work. But we really must spend time outdoors, and what better way to do that?
I see you are gathering quite a collection of succulents.
Semps, sedum and Jovibarba are all succulents belonging to the Crassulaceae family. Semps and Jovibarba are closely related, but have different growing habits.
Semps reproduce offsets on stolons with the offsets rooting while still attached to the parent rosette.
Sempervivum 'Ford's Spring'
Jovibarba have two different ways of reproducing.
The roller type produce offsets on very brittle, short stolons that break away from the parent rosette, causing the offset to roll away from the parent before rooting. This is very interesting to observe. They can even settle on top of their little heads, and some how right themselves to form roots. See how the tiny offsets are rolling away from the parent?
Jovibarba f/Col De Turini
Jovibarba heuffelii form their new rosettes from the parent rosette's crown/root. The only way to have new, separate plants from this type is to surgically divide them through the crown and root, using a clean sharp knife. You must have a healthy section of root attached to each rosette when doing this procedure.
These are all growing from the same crown/root system.

Aren't you lucky to have Tabby, picklepuff and t1nerbelle living close by. They are all a wealth of knowledge when it comes to growing succulents in your area of the United States.
I sure had a great time nursery hopping with you while we were visiting. Wish we lived closer.
