The Calathea triostar has a special feature: the leaves close when the amount of light decreases. The plant therefore has a day and night rhythm, which has earned it the nickname of 'living plant'. The closing of the leaves is also audible, with a rustling sound. The Calathea 'Triostar' is a real jungle plant and really does not like full sun. The Calathea 'Triostar' likes a high humidity, so spray the leaves regularly with rainwater to keep them nice and fresh looking. If the air is too dry, you will see the edges of the leaves dry out and turn brown.
