Any ideas what this is?

It looks like Orostachys malacophylla var. iwarenge:

Dunce's Cap (Orostachys iwarenge)

Scroll down for picture of immature plants.

That would be the one thanks Connie

Good call Connie.
Nice photo Daniel.

Thanks Lynn. I'm slowly adding a few sedums to the garden and found a piece of this in a homedepot shopping cart about 3 months ago and was thinking it was some type of a sedum . It grows likes crazy and I can't believe one little nearly dried up piece could do what it has done. I wish I could find Orostachys Malacophylla VAR Iwarenge 'Fuji'

You and me both. I would love to have that one. I have not found it offered anywhere in the U.S.

If I find it I'll share a pup with you

Thank you Daniel. I will send you something from my collection in return.
