About Peace Lily

The peace lily is one of the best indoor plants for Indian apartments because it tolerates low light and dramatically droops when thirsty — then recovers within hours of watering. It appeared in NASA's 1989 Clean Air Study. Later research showed that you would need hundreds of plants per room to match normal ventilation, so it is best enjoyed as a beautiful, easy houseplant rather than an air purifier.

Botanically known as Spathiphyllum wallisii, it belongs to the Araceae family. It is native to Tropical Americas and grows best in a tropical/shade climate. The parts most often used are the leaves (air filtering).
