Peace Lilies are elegant flowering houseplants known for their glossy dark green leaves and striking white spathes (modified leaves that look like flowers). They are one of the few flowering plants that bloom reliably indoors with minimal effort.
Care Guide
Light
Low to medium indirect light. One of the best flowering plants for low-light spaces. Direct sun will scorch the leaves. If it stops blooming, try moving it to a spot with slightly more light.
Water
Keep soil consistently moist but not waterlogged. Water when the top inch of soil dries out — typically every 5–7 days. The plant will dramatically droop when thirsty (it bounces back within hours of watering).
Humidity
50%+ preferred. Brown leaf tips are the classic sign of low humidity. Group with other plants or use a humidifier.
Temperature
65–80°F (18–27°C). Sensitive to cold drafts. Keep above 55°F at all times.
Soil
Rich, well-draining potting mix with peat moss. Likes slightly acidic soil (pH 5.8–6.5).
Fertilizer
Balanced liquid fertilizer monthly during spring/summer. Over-fertilizing causes brown leaf tips and reduces blooming.
⚠️ Toxicity
Toxic to cats and dogs. Contains calcium oxalate crystals causing oral irritation, drooling, and difficulty swallowing. Note: Despite the name, Peace Lilies are NOT true lilies and are not as toxic as Lilium species.
✂️ Propagation
Division during repotting. Separate clumps ensuring each division has roots and several leaves. Cannot reliably propagate from leaf cuttings.
Common Problems
Drooping → needs water (most common, bounces back fast)
Brown tips → low humidity or over-fertilizing
Yellow leaves → overwatering or too much direct sun
No flowers → insufficient light or needs fertilizer
Black leaves → cold damage or severe overwatering
Peace Lilies were part of NASA's Clean Air Study and were found to remove benzene, formaldehyde, trichloroethylene, ammonia, and xylene from indoor air — one of the best air-purifying plants tested.
