Peace lilies (Spathiphyllum), also known as closet plants, are a popular choice for offices and homes. When it comes to indoor plants, peace lily plants are some of the easiest to care for. But, while peace lily plant care is easy, proper growing conditions are still important.
Peace lilies are one of the best air filtering indoor plant. The NASA Clean Air Study found that Spathiphyllum cleans indoor air of certain environmental contaminants, including benzene, and formaldehyde.
Peace lily lives best in shade and needs little sunlight to thrive, and is watered approximately once a week. The soil is best left moist but only needs watering if the soil is dry. Peace lilies do not need frequent fertilizing. Fertilizing with a balanced fertilizer one to two times per year will be enough to keep the plant happy.
