The Peace Lily's charm lies in its elegant simplicity. Lush, deep green leaves rise from the base, framing its iconic white, spathe-like flowers. These flowers are modified leaves, surrounding tiny true flowers. Peace Lilies typically reach 1-2 feet tall, making them ideal for various indoor spaces. While some enjoy success growing them outdoors in warm climates, their adaptability to low light and moderate watering makes them perfectly suited for brightening any indoor environment.
Peace Lily flowers feature pointed white blooms that rise above spiking green leaves. This upright growth habit allows it to reach up to 3 feet tall, but it can be happily maintained in containers to suit your preference. Thriving in indirect light, it adds a touch of elegance and a pop of color to any indoor space. While not suited for outdoor landscapes in most climates, the Peace Lily brings its air-purifying properties and tranquil beauty indoors, with its lush, deep green leaves gracefully framing its iconic white flowers.
How to Care for Peace Lily (Spathiphyllum)
Peace Lilies grow best in bright, indirect light. They tolerate low-light conditions, making them popular indoor plants, but too little light may reduce flowering. Avoid direct sunlight, which can scorch the leaves. East-facing windows or filtered light through curtains provide ideal growing conditions.
Peace Lilies prefer well-draining, rich soil that retains some moisture without becoming soggy. A high-quality potting mix with peat moss, perlite, or coconut coir works well. The key is to balance moisture retention with airflow to prevent root rot.
Keep the soil consistently moist but never waterlogged. Water when the top inch of soil feels dry, usually once a week. Peace Lilies are sensitive to both overwatering and underwatering—drooping leaves are a sign the plant needs water. Use filtered or distilled water to avoid brown leaf tips caused by chlorine or fluoride.
Feed every 6–8 weeks during spring and summer using a balanced, water-soluble houseplant fertilizer diluted to half strength. Over-fertilizing can cause leaf burn or reduce blooming. Stop feeding during fall and winter when the plant’s growth slows.
Prune by removing yellow or brown leaves at the base of the stem. Cut off spent blooms once they fade to encourage new flowers. Regular pruning keeps the plant tidy and helps direct energy toward healthy, new growth.
Common pests include spider mites, aphids, and mealybugs. Overwatering can cause root rot or fungal leaf spots. Maintain moderate humidity, avoid soggy soil, and wipe leaves occasionally to prevent pest buildup.
No—Peace Lilies are not frost-tolerant. They thrive in temperatures between 65°F and 85°F and should be kept away from cold drafts or open windows. Exposure below 50°F can damage the foliage and stunt growth.
