Spathiphyllum wallisii, commonly known as peace lily,[1][2] white sails,[3] or spathe flower,[4] is a very popular indoor house plant of the family Araceae.

The plant produces offsets at the base and in time becomes a dense clump.

Spathiphyllum wallisii is one of approximately 40 species in a genus of tropical evergreens.

A number of cultivars, many of hybrid origin, are commercially available, such as the larger hybrids "Mauna Loa", named after the Hawaiian volcano, and the even larger “Sensation", which are both popular indoor plants.

Its wide natural range includes parts of Mexico, the Caribbean Islands, and northern South America.
