A Peace Lily (Spathiphyllum) is a popular, low-maintenance tropical houseplant known for its glossy green leaves and elegant white "flowers" (actually modified leaves called spathes) that signal when it needs water by drooping. They thrive in low to bright indirect light, prefer consistently moist (but not soggy) soil, and benefit from warmth, humidity, and occasional misting or pebble trays to keep leaves clean and dust-free, making them versatile for homes and offices.
