Peace lilies make excellent houseplants for the home or office. These lovely plants not only brighten up a living space, but are also excellent at cleaning the air of the room they are in. Most commonly, these plants have dark green leaves and white “flowers.” What most people think of as the flower is actually a specialized leaf bract that grows hooded over the flowers. Like many popular indoor plants, peace lilies enjoy medium to low light. Which kind of light you need to provide will depend more on what you want your peace lily plant to look like. Peace lilies that are placed in more light tend to produce the lovely white spathes and flowers more, while peace lilies in low light will bloom less and will look more like a traditional foliage plant.
