CDsSister, if you went to DBG, then you are in the Denver area? Some of us in the Denver area are quite willing to give away sempervivum.
As to the advantages of the different types of gardens - it depends on what you like and what space you have. I find the sempervivum, jovibarba, etc. do better in the ground than in pots, but I have many in pots that do pretty good. The nice thing about pots is you can move them around. It looks like you have a very nice hypertufa pot in your vertical garden. Sempervivum do very well in hypertufa pots.
I like the look of rock gardens, but I run out of space for the rocks so just end up with rockless gardens with rock garden plants.
t1nerbelle (Audrey) came over today and we went over to Timberline Gardens in Arvada. . That place is so awesome for semp and sedum lovers.
