The peace lily (Spathiphyllum Domino) is an evergreen, flowering tropical that has variegated white and green leaves with striking white blooms. The peace lily is most popular as an indoor plant, but you can grow peace lilies outside successfully if you live in a warm climate. If you give your peace lilies a suitable outdoor location, preferably shaded and moist, you'll have healthy plants with beautiful flowers. Caring for a peace lily that grows outside is slightly different than one kept indoors, however.
Plant your peace lily in partial shade, where it's protected from strong, direct sunlight. Your peace lily will flower better if it gets bright, indirect sunlight.
Plant your peace lily in either in a pot that you'll keep outdoors or in the ground. Make sure you plant the lily in rich, well-drained soil. The best environment for peace lilies is in soil that stays moist all the time but doesn't get soggy or pool water.
Water your peace lily once per week, unless you're getting adequate rainfall. Monitor the soil to make sure it isn't getting saturated, but allow the soil to dry out a bit between watering. You should notice that the foliage is drooping when the peace lily needs water.
Fertilize your peace lily regularly. Unlike peace lilies kept indoors, outdoor lilies need a nutritional boost to grow properly. Use a general plant fertilizer and follow the directions on the package.
