Spathiphyllum, commonly known as the peace lily, is a popular houseplant because it is so easy to grow. Spathiphyllum, according to the University of Florida Extension, is native to the tropical rainforests of South and Central America. The plants have dark, evergreen foliage and white spathes that enclose the plant's "true" flower.
Place your spathiphyllum in a spot that receives moderate to low light. It will bloom better with moderately bright light, but it can survive very low light conditions.
Water once a week during the winter, and more frequently when it is blooming. If you forget to water, you may discover your peace lily is totally wilted. However, it's an incredibly tough plant, and a good soaking will bring it back to life. Over-watering your spathiphyllum or leaving it in standing water is much more detrimental to your plant than under-watering.
Fertilize sparingly. If your plant is looking thin or hasn't flowered in months, use a liquid houseplant 20-20-20 fertilizer no more than every two months. According to the Clemson Extension Service, magnesium deficiency can cause peace lilies to become stunted, with the leaf tissue between the veins yellowing while the veins remain green. However, over-fertilizing can lead to leaves with brown edges.
Dust your plant's leaves regularly with a damp cloth.
