The peace lily is typically considered a houseplant. In warm humid regions, the peace lily(Spathiphyllum) can be planted in a shady border. However there isn’t a region in the United States where the peace lily can survive outside year round.

Peace lilies are found naturally in damp tropical forests in places like Costa Rica, Panama, Columbia and Venezuela.

My suggestion if you want it outside would be to place the potted peace lily in the shadeduring the warm months but take it inside during the cold months.
