i think some people call the ghost plant (Graptopetalum) but i dont know it for sure :)

I would say it's either Graptopetalum paraguayense or xGraptosedum 'Ghosty', depending on the bloom. Are the blooms white with a red spot/blotch on each petal? Or are they yellow? From the look of the petals, I'll guess it is the first, with white flowers. :) But let's hear what color, though, before I say that's for sure.

Thanks for replying. Here are some better images:

I need to rearrange them but they are so fragile I am reluctant to try.

So should I put them in a large trough type pot and just let them all grow together and some hang over the sides, or what?

Yes, with white flower, it is Graptopetalum paraguayense, (some call it by its common name, Ghost plant).

It's up to you how you have them planted-large pot or trough, together or separate. If you are not beheading them & the stems grow long, they will hang over the edge, as they are now. My hanging pot looks good like this. :) If they are in the ground, they will just root wherever they touch the ground as they grow.

rosemarie, thank you for the definite ID. I don't think I will put them in the ground just for the reason you mentioned. Thanks again.
