What's in the top L corner of the first pic you put, Gina?
I love smurfs!! The overall mass of each plant will increase, but not the size of the foliage, except for the leaf babies that haven't made any full-size leaves yet. You may need to trim occasionally, guide plants toward a particular direction.
I recognize Sedum lineare, another Sedum that may have been moved to Phedimus, and some of the other bigger ones look like possible hybrids, like Sedeveria.
Carpet Sedum (Sedum lineare 'Variegatum')
