Spathiphyllum, also known as a peace lily, is a popular indoor plant not only because of its glossy, dark green foliage and long-lasting flowers, but because of the plant's ability to thrive in low light. The showy blooms start out as a pale green and gradually turn to sweet-smelling, creamy white flowers. In spite of its exotic beauty, Spathiphyllum is an easy-to-grow plant with few demands.
Place Spathiphyllum in bright, filtered light. Avoid placing the plant directly in a sunny window, which can scorch the plant. Spathiphyllum can grow in very low light, but will do best a few feet away from a window, or near a window covered with a sheer curtain.
Water when the top of the soil feels slightly dry to the touch, but don't allow the soil to become bone dry. Excessively dry soil can cause the edges of the leaves to turn brown. Water the plant with water at room temperature.
Keep Spathiphyllum in a warm room, with daytime temperatures between 65 degrees and 85 degrees Fahrenheit, and nighttime temperatures slightly cooler.
Fertilize every two to three months, using a balanced fertilizer for indoor plants. Withhold fertilizer during the winter months. Spathiphyllum is a low-feeder, so an occasional forgotten feeding won't damage the plant.
Clean the leaves occasionally, as the wide, shiny leaves will collect dust, which will block sunlight and air. Dust the leaves with a soft, clean cloth.
