Unknown Succulent Found and Potted

[Update 8/29/16: It’s a Sedum dendroideum subsp. praealtum]

I found this succulent under our Bosc Pear Tree when I was doing some garden clean up and thought I would pot it up.

These have been growing along one of our fence and my Mom seems to think that may have popped up from our neighbor’s yard.

We never really took much notice or it, but when I saw this good sized multi-branch which was already partially rooted, I thought it would look much better properly potted up and given more light.

I’m not really sure what it is. My Mom thinks it’s a Jade (Cassula sp.) while I think it may be a type of Aeonium… We don’t know.

Anyone know what it is?
