Native to Central and South America, the calathea require the right conditions to thrive. The calathea has many common names including the prayer plant, the rattlesnake plant, or the peacock plant. They love bright indirect light and a light, well-draining potting mix. Keep them out of direct sun and make sure their soil stays evenly moist, but not wet. A good rule of thumb is to water when it is about a third dry.
