The closet plant is more commonly known as the peace lily. It is an evergreen perennial flowering plant, native to South America and Asia. Generally the closet plant is used as an indoor plant where it is easy to grow and care for. A bonus for owners of the closet plant is that, according to NASA, it actually helps to clean the air of potentially harmful gases (Zone 10).
Locate an area of the home that has temperatures between 68 and 85 degrees F during the day, and no cooler than 55 degrees F at night. This temperature range provides suitable conditions for the closet plant.
Provide your closet plant with the appropriate amount of light. Though the closet plant can survive in low light--even a dark corner of the room is sufficient--it favors bright filtered light. Keep the plant at least 5 feet from a window.
Water the closet plant thoroughly and then allow the surface of the soil to dry before watering again. If the leaves droop, it is time to water. Use room-temperature water and, if your tap water has high chlorine levels, consider using bottled water.
Mist the plant at least three times a week by spraying it with water from a misting bottle.
Wipe the leaves of the closet plant when they get dusty with a damp, soft cloth.
Fertilize the closet plant every three months with a balanced, liquid fertilizer, such as a 20-20-20 fertilizer.
