Radiator plant Peperomia graveolensThe main feature of the radiator plant (Peperomia graveolens) is its beautiful leaves. The colours and patterns on the leaf will draw all eyes. The Peperomia has a striking red colour on the underside of its leaves. This makes it perfect for combining with other succulents, though it also more than holds its own as a lone specimen. Put the Peperomia in a bright spot, but away from direct sunlight. The radiator plant doesn't need a lot of water;
