Peace lilies, also known as spathe flowers or spathe lilies, are an easy-to-grow indoor plant that can express purity, support, forgiveness, and healing. Peace lilies are often given as a housewarming or sympathy gift.  They are a great air purifier as well.

They don't need direct sun, preferring bright, indirect light from a nearby window. They'll grow just fine across the room from a window but won't bloom well in such low light and may also become leggy. Give them evenly moist, well-drained soil and temperatures of at least 55 degrees. If peace lilies wilt every two to three days, repot them in larger containers, which don't need watering as often. Fertilize plants growing in bright light about every six weeks with a liquid 20-20-20 product. Feed plants growing in low light half as often. About every six months, take them outside, and flush them with water to remove salt buildup from fertilizer.

Peace lilies contain calcium oxalate crystals that can cause burning of the lips, mouth and throat, vomiting, and difficulty swallowing if ingested by pets or humans.
