Peace Lily

Spathiphyllum wallisii

Updated Jul 26, 2026

Peace Lily (Spathiphyllum wallisii) is a shade-tolerant indoor plant with glossy leaves and white spathes that grows best in low to medium light, warm rooms, and moist well-draining organic soil.

About Peace Lily

Peace Lily is a shade-tolerant indoor plant grown for its glossy green leaves and elegant white spathes. It works especially well in homes and offices where the light is too soft for many other flowering houseplants.

The foliage stays attractive even when the plant is not blooming, and in better light it produces white spathes more regularly. That combination makes Peace Lily useful both as a foliage plant and as a reliable indoor bloomer.

It performs best with warm indoor temperatures, a rich mix that drains well, and a watering routine that keeps the soil evenly moist without leaving the roots in stagnant wetness.

How to Care for Peace Lily

Watering

Water moderately, keeping the soil evenly moist but not waterlogged. Let the top inch (2–3 cm) of the mix dry slightly before watering again, then water thoroughly until excess drains away.

Peace Lily should never sit in standing water, because constant saturation can lead to root rot and yellowing leaves. If the plant wilts between waterings, that usually means it should be watered a little sooner next time rather than being kept on a harsher dry cycle. Room-temperature water is best.

Sunlight

Provide low to medium indirect light. Peace Lily stays green in lower light better than many houseplants, but it usually blooms more reliably in bright filtered light set a little back from a window.

Strong midday sun through glass can scorch leaves and bleach the spathes. If the sunniest side starts to look pale or scorched, the plant is likely receiving too much direct sun.

Temperature

Keep the plant in moderate, stable temperatures, ideally around 64–77°F (18–25°C). Peace Lily does not respond well to cold drafts or sudden temperature drops.

Avoid placing it next to exterior doors, cold winter windows, heaters, or air conditioners. Brief cooler periods are usually tolerated, but prolonged cold can slow growth, damage leaves, and reduce flowering.

Humidity

Aim for moderate humidity, with a little more if possible. Peace Lily can live in typical indoor air, but very dry heated rooms often lead to browning at the leaf tips.

Grouping plants, using a pebble tray below the pot, or placing Peace Lily near a small humidifier can help. Light misting is optional, but leaves should not stay wet for long in cool rooms.

Soil

Use a rich, organic, well-draining potting mix. A quality houseplant mix containing coco coir or composted bark, along with some perlite, works well.

For Peace Lily, the mix should hold gentle moisture and nutrients while still allowing water to move through fast enough that the roots are not trapped in a heavy soggy mass. A pot with drainage holes is essential.

Feeding & Grooming

Feed lightly during spring and summer every 4–6 weeks with a balanced, diluted houseplant fertilizer. Peace Lily usually performs better with modest feeding than with heavy doses.

Too much fertilizer can cause brown tips and salt buildup. Remove yellowing leaves and spent spathes at the base, and wipe the broad leaves from time to time so Peace Lily stays clean and keeps its natural gloss.
