Out of 1,000 species of peperomia, only 100 are raised in the U.S. (many by collectors). A handful of varieties are raised as easy-care, low-growing houseplants. Peperomia are commonly found in pots three to six inches in diameter and hanging baskets up to 10 inches in diameter. Plants that grow upright or have rosettes make good potted plants.
Peperomia prefer warm spots with periods of direct sunlight. These are semi-succulent plants that require light watering. Peperomia can be planted in most flower gardens and brought indoors before the frost arrives. Perennials that survive solely outdoors are common to tropical and subtropical regions.
Peperomia are compact plants with short, thick stems and fleshy leaves. Some species are planted as ground cover. Peperomia leaves may be green and striped or bordered with pale green, red, or gray, while the flowers are tiny corded spikes. Propagation is done by separation of roots, stem cuttings, or seeds. Peperomias are susceptible to a variety of diseases caused by viruses, bacteria, and fungi. Root rot occurs when the plant is exposed to excess moisture. Mealybugs can be destructive pests, and exposure to drafts can be fatal.
