I'm curious what the purpose of hybridizing with this species might be. Are enthusiasts trying to incorporate its curious growing habit into something with more attractive foliage or something maybe?

That makes sense - I was at a distance shooting the blue-gray bird with a smaller lens and by the time I reached him, he flew into a thicket and when I looked into the thicket I found the catbird. They didn't seem like one and the same bird. Thanks for the IDs, TMFF, and clearing up my confusion. Shyamala

I would go with one of the many varieties of graptosedum, or sedeveria.

Hablu, how big is this E. Albicans? Mine is very small, bought it in 1-inch pot.
