Also called String of Turtles, Creeping Peperomia is an easy-to-grow houseplant with small, green, rounded leaves that display purple venation on new growth that matures to white as the plant ages. Brighter light results in more intense colors. It looks great in a hanging basket where it can attractively display its cascading foliage. Water lightly when the soil is dry since the succulent-like leaves store water. Creeping Peperomia is an ideal plant for a terrarium or vivarium since the small foliage has a creeping habit and it thrives in high humidity.
