Peace lilies flower best in bright but indirect light, and usually flower in spring, producing one or two white hooded blooms that can last for over a month. They may occasionally flower again in autumn. Once the flowers have faded, deadhead them to keep the plant looking neat.
How do I get my peace lily to flower?
Peace lilies are very tolerant of low light, but low light doesn't mean no light! To encourage flowering, move the plant to a brighter location, where it will receive bright, indirect light. Green flowers, weak-looking flowers, or a general lack of flowers can be caused by improper fertilizing.
How often do peace lilies bloom?
Healthy peace lily plants will bloom twice a year, in spring and again in fall. The flowers usually last for one to two months before turning brown.
