Peace Lily
Spathiphyllum wallisii
Peace Lily. Spathiphyllum wallisii, the peace lily, is an evergreen rhizomatous perennial native to the tropical understory of Central and South American rainforests. Glossy lance-shaped leaves form a dense clump from which white sail-like spathes rise on slender stalks, surrounding a creamy white spadix that is the actual flower. Among the most tolerant houseplants of low light and one of the few that visibly droops for water and recovers within hours.
Growing & care
- Light: medium to low indirect. Tolerates rooms with no direct sun. Bright direct light bleaches leaves.
- Water: when the leaves begin to droop slightly — peace lily is unusually communicative about thirst and bounces back fast. Water with room-temperature distilled or filtered water; fluoride and chlorine cause brown leaf tips.
- Soil: any well-drained potting mix.
- Pot: slightly snug; peace lilies bloom more reliably when modestly root-bound.
- Humidity: 40%+ ideal; mist or place on a pebble tray in dry rooms.
- Fertilizer: monthly during spring/summer at half strength; skip in winter.
Propagation
Divide established clumps in spring when the plant becomes crowded. Lift the entire root mass, rinse off soil, and separate at the rhizome with a sharp knife — each division needs at least 2–3 leaves and visible roots. Seed propagation is not practical for home growers.
Common problems
Brown leaf tips trace to tap-water chemicals or low humidity more often than under-watering — filter water and run a humidifier in winter. Yellow leaves indicate overwatering or normal aging of oldest leaves. Lack of blooms usually means too little light; move closer to a window. Despite the name, peace lily is not a true lily and does not cause kidney failure in cats — but it does contain insoluble calcium oxalates that cause oral irritation, drooling, and vomiting in dogs and cats. Keep out of pet reach.
