How to care for Peace Lily
Spathiphyllum wallisii · Araceae
An elegant, shade-tolerant aroid with glossy dark leaves and white sail-like flower spathes that appear off and on all year in good light. It is famously communicative — the whole plant droops theatrically when thirsty and stands back up within hours of watering. Despite the name it is not a true lily. Water roughly every 5 days while it's growing (about every 9 in winter), give it a bright room away from the window, kept above 59°F (15°C) — average room humidity suits it.
Care at a glance
Keep evenly moist and water at the first hint of drooping; use filtered or rested tap water if leaf tips brown.
Tolerates low light but flowers reliably only in medium to bright indirect light; no direct sun.
Half-strength balanced fertilizer every 6 weeks; overfeeding browns the leaf tips.
Mistakes that kill this plant
- Repeatedly letting it collapse from drought — each wilt costs it leaves.
- Leaving it standing in a saucer of water for days.
- Cold drafts and temperatures under about 55°F (13 °C).
Seasonal tips
- Cut spent flower stalks at the base to redirect energy to new blooms.
- In winter, let it dry slightly more between waterings but never fully.
- A slightly snug pot encourages more flowering.
