Description

Peperomia is a genus of small, perennial houseplants that have over 1000 species, each having unique characteristics. This group of plants is a member of the black pepper family, Piperaceae. The plants are native to the tropical and subtropical areas of Central and South America, Africa, Southeast Asia, and parts of Australia. They are found in rainforests and thrive in areas that are warm and humid.

The genus name, Peperomia, originated from the Greek word for pepper, peperi, and from homoios which means resembling. In other words, the genus name implies the plant is very similar and related to the black pepper plant, Piper Nigrum. The common name, Radiator Plant, references their preference for warm conditions. Many species of Peperomia are used as houseplants or greenhouse plants. In warm climates, they are used as garden plants.

They are popular houseplants because of their easy care, compact habit, and their beautiful ornamental foliage. They usually reach a height of 6 inches to 1 foot and are equally as wide. The species have a variety of leaf textures, colors, and shapes. The leaves may be heart-shaped, lanceolate, rounded, or oblanceolate, and they may be green, blue-green, silver, brownish, or may have a variegated leaf pattern. The leaf texture also varies from smooth, glossy, fleshy, or fuzzy. Many species are succulent-like and can store water in their fleshy leaves. Their growth habits also vary from erect, bushy, trailing, cascading, or climbing. In their native habitats, these plants will also produce small, flower spikes that are greenish-white to brown during the summer. Typically, as a houseplant, they will not flower. 

They are winter hardy in USDA hardiness zones 10 through 12.  They prefer bright indirect light and will tolerate low light conditions. Moist, well-drained, soil mixture of loam and sand is recommended. Avoid overwatering and protect them from cold drafts. They are adaptable and can thrive in the humidity levels of most homes, but if your home is very dry consider a humidifier. They are typically slow-growing and will not need to be repotted very often. Propagated by leaf cuttings, stem cuttings, or divisions, depending on the species.

Peperomia plants are perfect plants for a desk or tabletop in the home or office. Some species are perfect for hanging baskets while others can be used in terrariums. The decorative foliage will bring a splash of color to any indoor space.  

Insects, Diseases, and Other Plant Problems:  Monitor for mealybugs, spider mites, aphids, scale, fungus gnats, and whiteflies. Root rot and yellowing or curling of the leaves indicate overwatering. To prevent leaf spots, avoid wetting the leaves and provide good air circulation. Direct sunlight can scorch the leaves.
