“Crinkle leaf plant”

Another common name is [apparently] “Key Lime Pie,” but it’s the “crinkle leaf” characteristic that attracts my attention every time I walk by this pot in the cactus (succulent) house. My faculty colleague in the Department of Plant Biology (and my botanical-mentor) likes this plant because of the “potsticker-like” appearance of the leaves. Thanks for another late-night ID, Dan! When it blooms, it will send out shoots with small white flowers.

Scientific name: Adromischus cristatus (family Crassulaceae).
