Peace lily (Spathiphyllum) is a popular indoor houseplant valued for its glossy green leaves and elegant white “flowers” (actually a modified leaf called a spathe). It’s one of the easiest decorative plants to grow indoors, especially for beginners.
🌿 Basic Description
- Scientific name: Spathiphyllum
- Type: Tropical evergreen perennial
- Appearance: Dark green, lance-shaped leaves with white hood-like blooms
- Size: Usually 30 cm to 1.2 m depending on variety
☀️ Light Requirements
- Prefers low to medium indirect light
- Can survive in low light areas (offices, shaded rooms)
- Avoid direct sunlight—it can scorch the leaves
💧 Watering Needs
- Likes consistently moist soil, but not soggy
- Water when the top 2–3 cm of soil feels dry
- Overwatering can cause yellow leaves and root rot
- Underwatering leads to drooping leaves (it usually recovers quickly after watering)
🌡️ Temperature & Humidity
- Ideal temperature: 18–27°C
- Doesn’t tolerate cold drafts or temperatures below ~10°C
- Loves high humidity, but adapts to normal indoor conditions
🌸 Flowering
- Produces white blooms mainly in spring and summer
- In good conditions, it may flower multiple times a year
- Lack of light is the most common reason it stops blooming
🧪 Air Purification
- Known for filtering indoor air pollutants like:
- Formaldehyde
- Benzene
- Carbon monoxide
(This is why it’s often used in homes and offices)
⚠️ Toxicity
- Toxic to cats, dogs, and humans if ingested
- Contains calcium oxalate crystals → can cause:
- Mouth irritation
- Drooling
- Vomiting
🌱 Soil & Fertilizer
- Use well-draining potting mix
- Fertilize lightly every 4–6 weeks during growing season (spring/summer)
🌿 Common Problems
- Yellow leaves: overwatering or poor drainage
- Brown tips: dry air, underwatering, or too much fertilizer
- Drooping leaves: usually thirst, but also can be root issues
- No flowers: low light or nutrient deficiency
🌱 Propagation
- Best done by division (splitting the plant during repotting)
- Each section must have roots and leaves
