We've had this plant in many times before, but it continues to dazzle us every time with its glossy, thick, green and yellow/white leaves.
Light: Does best in bright, indirect light, but can also handle lower light levels. Not enough light will lead to paling leaves and loss of variegation.
Soil: Use a well draining potting mix.
Humidity: These guys like humidity. Mist often, or keep near a humidifier.
Fertilizer: Fertilize once a month using a water soluble houseplant fertilizer. Do not fertilize over winter months.
