This cute little Peperomia is found in Peru and Ecuador, and perhaps elsewhere in South America.  Its leaves only grow to be about 1″, and the entire plant stays under 6″ in my experience.  Perhaps given something to lean on, it could get a little taller.  It is tolerant of a wide variety of terrarium conditions, but doesn’t seem to like standing water on its leaves.

Available plants are cuttings at least 6″ long with many leaves. They will be shipped in moist paper towel in a bag.
