Peace Lily
Spathiphyllum wallisii
A popular indoor plant known for its dark green, glossy, lance-shaped leaves and distinctive white spathes that look like flowers.
- Light
- Medium to bright indirect light; direct sunlight can scorch the leaves, while too little light prevents blooming.
- Water
- Water when the top inch of soil is dry. The plant 'tells' you it is thirsty by wilting dramatically, but quickly recovers after watering.
- Growth
- Clumping herbaceous perennial; typically grows to 1-4 feet depending on the cultivar.
Care instructions
Place in bright, indirect light; keep soil consistently moist but never soggy; feed every 6 weeks in spring/summer.
