This grower is fairly sure of this plant identification.
Very similar to the ghost plant, the sugar almond plant (the leaves aren't edible!) has more of a powder white farina that protects them from direct sun. This marks easily when touched. Tiny bright red flowers held deep in rows of white cups-(Summer).
Moonstones, Sugared almond plum
Pachyphytum oviferum (Moonstones). This is a perennial succulent with rosettes of bloated, spoon-shaped, blue-green leaves with a whitish red, powdery coating. The flowers are a deep red-orange or pale green, they will appear in short-stemmed, pendent clusters from late winter to early spring.
They will need full sun with a little shade, with moderately fertile, very well-drained soil. You can propagate from seeds or cuttings.
