Eternal Flame Plant Calathea crocataThis 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 Calathea crocata owes its nickname 'Eternal Flame' to the orange flowers protruding above the foliage. 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,
