Calathea makoyana, also known as cathedral windows or the Peacock plant, is a evergreen perennial. They are also part of a group called "prayer plants" because they will roll up ther leaves.
Despite being a tropical species, peacock plants are not fans of intense, direct sunlight. This can cause the patterns and colors on the foliage to fade. Filtered light conditions are recommended, but these plants can also grow in full shade, although this can slow down growth significantly.
Peacock plants like medium moisture but not standing in water or soggy soil. Water with rainwater, filtered or bottled water at room temperature when they are partially dry (They don't like hard water). Check all the way around the plant for moisture levels. Using a moisture meter may be helpful too.
