Calathea zebrina has velvety patterned ovate leaves which are light green in colour with darker green stripes, like Zebra stripes. The underside of the leaves are purple and not always visible because leaves grow horizontally (although some will curve or grow more upright). It's a clump forming plant that produces long stalks (up to 1 metre tall) and the leaves (40cm or more in length) sit at the top .
Calatheas love a warm but shaded spot in greenhouses or conservatories, but anywhere indoors without cold drafts and enough light is suitable. A bright bathroom large enough to house the plant can be a good location, because of the higher moisture levels.
During the growing season water the plant thoroughly and keep the soil moist (remember this plant loves moisture). When it's winter growing slows down or stops, reduce watering and you can allow the top soil to become slightly dry between each watering. If you can - use tepid rain or distilled water and avoid cold hard water.
Misting and keeping the soil moist will help with humidity but if you can and if your plant is showing signs that it's needed - use a humidity tray or electronic humidifier. Placing the Calathea near other plants will also improve humidity.

Potential Calathea Problems
Leaves curling and spots: The most likely cause here is underwatering. Check the soil for dryness and provide water - following the above instructions.
Leaf tips brown: Your plant is most likely needing more humidity because the current air quality is dry.
Leaves dropping: Again, the air could be too dry and the humidity may need to be increased.
Limp stems: Limp stems usually happens when the plant is getting too much water during the winter and the temperature is possibly too low. This can lead to the stems rotting.
