I would like to see an actually size of the leaves for Identification, I would need to know if this was grown in shade, or part sun. Thanks,

not lactea this plant have spots around the leaf not in the mid, and more green .a hybrid of arborescens ??or is it more hanging?
Cok.

Or Crassula "silver dollar"

Or a crassula flammea...that becomes red in full sun exposure and few watering!!!

Probably Crassula capitella ssp. capitella.

Crassula arborescens.

Easily distinguished from allied C.ovata by the glaucous leaves.
