It's a member of the Crassulaceae for certain, possibly a Sedum. I hope that's a starting point.

Looks like the cultivar Sedum 'Adolphi'- I think 'Adolphi' is a cultivar - maybe a species? I could be thrown off by not having anything for scale. WS

Sedum nussbaumerianum looks similar to that, too.

It sure looks like something I have that was labeled "Sedum Adolphi, Golden Glow," when I bought it. Of course, that was a Home Depot label, so it may not be accurate. I love this plant for its color and because it grows so well under benign neglect. I have it in the ground.

I vote for Sedum adolphi also. Golden Sedum it's called. My mom has a nice big pot of this indoors, it's a beautiful plant. Give it full sun & you'll really see the colors come out!

I vote for Sedum nussbaumerianum, although yours isn't quite as highly colored as it can get. Do a Google search on that name and look at the Images, and see if you agree.

It is Sedum nussbaumerianum. Give it more sun, and it get a golden - yellowish looking.
