Spathiphyllum, generally known as peace liliy, is a genus of 50-60 species of the flowering plants. They are native to America and South East Asia. Because of their decorative leaves, and long-lasting flowers, several of them are popular houseplants. They belong to the Araceae. Even though they are called "lillies", they are not closely related to the true liliy family, Lillaceae. They are perennial, and grow from bulbs, same as the true lilies.
