I'm thinking maybe a xSedeveria hybrid, but I'm having trouble tracking down the exact one, Does it get flowers, Adam?

This looks like Burro's Tail of Donkey's Tail succulent. They'll create long cascading chains which is ideal for hanging baskets.

Bathgate you beat me to it! I think the same as you.

It could be straight Burro's Tail, but it looked pretty short and branchy to me, so that's why I started looking at the hybrids first.

Sedum morganianum Burrito / Burro's tail.
Mine was like this when I bought it but it has grown longer now.
