Peace lily is a common houseplant that bears broad, dark green leaves and charming, white calla-like flowers on tall stems above the foliage. When in bloom, the plant looks best when grouped in clusters of three or more. Peace lily fits in well in just about every style of interior design, particular country and causal looks. Large specimens look great on the floor; smaller peace lily plants are perfect for tabletops or plant stands. Because peace lily is one of the most efficient houseplants at filtering indoor pollutants from the air, it's a great pick for bedrooms.
Peace lily blooms best in high-light situations. It will tolerate low-light conditions well, but won't bloom much, if at all, so keep lighting in mind if the flowers or foliage is more important to you.

Water peace lily enough to keep the potting mix moist, but not wet or soggy. The plant will wilt dramatically when it gets too dry, but happily, its leaves pop back quickly after it gets moisture. 

Being a tropical plant, peace lily prefers high levels of humidity. If the leaf edges turn brown, supply more humidity by grouping it with more houseplants (which release moisture into the air as they breathe) or set it on tray of gravel and water so the pot sits on top of the gravel, above the water. 

Fertilize peace lily once or twice a year (every six months or so) at the minimum. You can fertilize your plant more frequently if you wish, especially if you want it to grow faster or bloom better. You can use any general-purpose fertilizer; peace lily isn't particular as to types or brands. Do be sure the follow application rates as recommended on the product packaging. 

Note: Peace lily is not intended for human or animal consumption.
