The Peace Lily or Spathiphyllum is a tropical flower native to parts of  the Americas and South East Asia.  While this plant can be grown outside  in some areas, it also makes for an attractive and even common  houseplant due to its easy care and charming beauty. Peace Lily is not a lily at all, but rather is a member of the Araceae family. While there are 47 different varieties of Peace lilies most of these  plants look very similar.
