Spathiphyllum — the peace lily — is loved because it communicates: it flops dramatically when thirsty, then springs back after a drink. It also flowers indoors, which few easy plants do.

The drama is a feature

A peace lily that flops at 5pm is usually fine by morning after water. Don't panic; just don't let it stay wilted often.

Getting blooms

White "flowers" (actually spathes) appear with bright, indirect light and steady moisture. If yours never blooms, it likely wants more light. Brown leaf tips usually mean dry air or tap-water fluoride — use filtered water.

Why are the tips brown?

Low humidity or fluoride in tap water. Filter the water and raise humidity.

Is peace lily toxic to pets?

Yes. Keep away from cats and dogs.

Getting blooms and clean tips

Peace lilies flower with bright indirect light and steady moisture. If yours never blooms, it likely wants more light. Brown leaf tips almost always mean dry air or fluoride in tap water — switch to filtered or rainwater and raise humidity with a pebble tray. The dramatic flop is a thirst signal, not a crisis; water promptly and it recovers within a day.

Peace lilies are communicative — that's their gift. Learn its flop, and you'll rarely lose one.
