Calathea is a group of plants with one of the most exotic and beautiful foliage you can find. They change position slightly during the day in response to changes in temperature and humidity or moisture requirements.
It is not very easy to care for, but well worth the effort.
Calathea likes bright indirect light, never placing in direct sunlight.
They are sensitive to the water, the best way is to use distilled water, rain water or you can use tap water if you allow it to sit out overnight before watering.
Humidity is very important for Calathea. Misting or a humidifier can help. You may also need to place the plant pot on a tray with wet pebbles.
Calathea is non-toxic plant.
