A Peace Lily (not really a true lily) or Spathiphyllum originated in tropical forests around the world where it grew close to the forest floor in the shade of larger plants. This helps explain why it is one of the few indoor plants that bloom even in medium to low light. A Peace Lily is a member of the Araceae family and a relative of the Alocasia, Dieffenbachia, Caladium, and Philodendron. All plants in this family contain calcium oxalate crystals and are very poisonous.
Peace Lily Description
A Peace Lily is a beautiful, indoor houseplant that grows between 1- 4ft tall. It has large, glossy, oval, dark green leaves. The leaves do not develop on stems but come directly out of the soil. What we think of as the “white flowers” are really modified leaves called spathes that surround the real, inconsequential flowers. The “flowers” start out as light green and, as they mature, turn white. These tall, impressive white “spathes” (flowers) last for several weeks.

Quick Care Tips
Wait until leaves get soft and droop a little before watering
Grows slowly in low to medium light, but needs bright indirect lightVery few houseplants should be placed in direct sun. High light refers only to bright indirect light since direct sun often burns the leaves of indoor houseplants. An area that is too hot and dry encourages Spider Mites and causes blooms to quickly fade. A northern exposure really doesn't provide enough light for high light plants. These plants need to be placed directly in front of an east-facing window, within 1-3 feet of a west-facing window, and within 5 ft. of a south facing window. A high light area has over 300 ft. candles of light. to flower
Do not over feed or leaf tips burn
Avoid temperatures below 55°F
The tips of the leaves of Peace Lily plants usually turn brown from too much water, too much fertilizer, too much fluoride, chlorine, or salt in the water, or sitting in a location that is too hot.
To help your Peace Lily produce flowers, first move it to a brighter area. I’ve also found that if you stress the plant by allowing the soil to dry out before watering, it produces more flowers.
The leaves are turning yellow because the soil of your Peace Lily is getting a little too dry before you water. Water the plant a little more frequently and I think the yellow leaf problem should disappear.
Your Peace Lily may be getting too much light. Move it to an area where the light is not quite as intense, perhaps an east or north-facing window. If the plant leaves are still pale, try a basic houseplant food diluted to ½ the recommended strength.
