This little one also needs to sleep at night! During the day the Calathea cleans the air in the room, and at night it sleeps. The Crocata does this by pointing its leaves straight upwards in the evening.  The plant grows all year round; the flowers bloom for 2 or 3 months a year. This jungle plant needs high humidity. Always keep the soil moist, without letting the plant stand in water. Spray the leaves at least once per week.
