Peperomia rotundifolia, also known as jade necklace, trailing jade, creeping buttons and round leaf Peperomia, is a trailing plant species of peperomia native to the tropical rainforest of South America.
 
Bright light without direct sunlight is best suited. A small amount of morning or evening sun won't harm, but midday sun could scorch the leaves and harm the plant.
 
Overwatering is the worst offender for most Peperomias including this species. This is because of its succulent nature and small roots . Allow the soil to become dry then water thoroughly. During the winter reduce watering to a minimum.
 
This plant is non-toxic to cats and dogs and is a great air purifier.
