The more I look at it, the more it looks like pix of Graptopetalum paraguayense I see online, with that tight rosette and the long stem (this one is about 30 cm). However, it doesn't look like the plant I already have labeled G. paraguayense ...though I guess it could be differences due to environment...hmm. Will post a photo later. Curious to hear what you plant people think...

Very hard to tell without flowers.
Paraguayense(hybrid) I should say.
I have two more candidats: x Graptoveria 'Blavä' and Gr. helios. (both probably wrong guesses)

Thanks Hablu,
Hopefully I can get this one to bloom for me after a summer outside next year!

Happy growing,
Breton

It is such a pristine plant ~can't say I've seen one that neat! If you see yellow blooms, I'd lean toward x Graptosedum 'Ghosty'. But, hard to say without the blooms.Nice that you go a piece back after losing it. Pay it forward...that kindness! :)
