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.
This distinctively marked Marcgravia (no pun intended) is from Ecuador and seems to be one of the easier species to grow, and is rather quick once established. The intense white leaf venation gets more dramatic as the plant matures, with new foliage looking rather bland in comparison. The maroon stem offers a nice contrast.
A more elaborate frond than the true ankersii, this one is also painfully slow and has an even thinner membrane than ankersii. The fronds are about 3″ but only stand an inch off the ground as they are kept low by the weight of the fronds.
