Your photo is beautiful Arlan. Makes me want to reach out and touch it. : ) I don't remember what growing zone your in. Do you take it indoors for the winter?
Here is my above posted plant last year when it was sent to me in a trade as Ghost Plant. It definitely has a different shape to the leaves that the one I got from you. I'll have to go out and take a photo of it to compare them side by side.
Graptopetalum paraguayense 'Ghost Plant' 3/21/2010
Found this link to Plant Delights Nursery. The grow it in conditions down to 7°F and have it survive. Needs protection from to much moisture in cold conditions. Wow, mine had none stop rain for months this winter and survived down into the mid teens a few times during winter.
