Height: 8 in (20 cm)
Light: Low to bright light. Protect this plant from direct sunlight. Light from an east- or north-facing window works best. Peperomia caperata thrives under indoor grow lights, making it a good choice for an office plant.
Water: Keep soil barely moist. Allow the top inch of soil to dry between waterings. Water less in winter, allowing the top half of the soil to dry out before watering again.
Humidity: Moderate -- around 40-50% relative humidity. Use a humidity tray or room humidifier, if needed. Or put your plant in an open terrarium -- it thrives in the moist air like its native rain forest habitat.
Temperature: Average room temperatures (65-75°F/18-24°C) year-round.
Soil: Light peat moss potting mix that contains perlite or sand to help drainage. Peperomia likes some air around its roots. This plant will easily get stem and/or root rot if the potting medium is kept wet.
Fertilizer: Feed monthly spring through fall with a liquid or water-soluble fertilizer, diluted by half. Stop feeding in winter, when growth is slow.
Propagation: Take leaf or stem tip cuttings in spring.
