Spathiphyllum is a genus of around 50 species of clumping, evergreen perennials native to the forest floors of tropical Central America and Southeast Asia. The typical aroid-type inflorescences are made up of a leaf-like spathe and spike-like spadix. The leaves are dark green and glossy. Commonly called peace lilies, these plants are popular houseplants and indoor landscaping plants. They flower freely if provided the proper growing conditions.
