Bring calm, clean style to any room with the Peace Lily. Its rich green leaves and signature white blooms make an instant upgrade for desks, living spaces, and reception areas—while its forgiving nature suits busy schedules. Place it in indirect light, water when the soil surface dries, and enjoy a polished, professional look all year round.

1. Basic Identification

Common Name: Peace Lily (الشراع)
Botanical Name: Spathiphyllum wallisii
Variant: Standard
Color: Natural
Country of Origin: Iran
Family: Araceae

2. Taxonomy & Classification

The Peace Lily belongs to the kingdom Plantae and the family Araceae. Specifically, Spathiphyllum wallisii is one of the most popular species within the genus Spathiphyllum, known for its distinct flowering structure consisting of a spathe and spadix.

3. Origin & Distribution

Native to the tropical rainforests of Central and South America, particularly regions in Colombia and Venezuela. It has since been cultivated globally and is highly valued as an indoor ornamental plant in diverse climates.

4. Visual Characteristics

This plant features glossy, lance-shaped, dark green leaves that grow directly from the base. Its most striking feature is the white, hood-like leaf called a spathe, which surrounds a central cream-colored spike (the spadix) where the true tiny flowers reside.

5. Size & Dimensions

Under indoor conditions, the Peace Lily typically reaches a height of 30 to 60 cm (12 to 24 inches) and spreads roughly as wide, forming a dense, attractive clump of foliage.

6. Light Requirements

Thrives in bright, indirect sunlight. While it is highly adaptable and can tolerate low-light environments, it requires filtered light to produce its iconic white blooms consistently. Avoid direct sun, which can burn the foliage.

7. Watering Needs

The Peace Lily prefers consistently moist soil but should never sit in water. It is famously communicative, "fainting" or drooping its leaves when it is thirsty, and usually recovers quickly once watered. Water when the top inch of soil feels dry to the touch.

8. Soil & Potting

Requires a well-draining potting mix rich in organic matter. A peat-based mix with perlite is ideal to ensure moisture retention without causing root suffocation. It enjoys being slightly root-bound.

9. Temperature & Humidity

Thrives in standard indoor temperatures between 18°C and 27°C (65°F–80°F). Being a tropical native, it appreciates high humidity levels; using a humidifier or misting the leaves can help prevent brown leaf tips.

10. Fertilization

Feed with a balanced, water-soluble fertilizer every 6 to 8 weeks during the growing season (spring and summer). Reduce or stop fertilization during the winter months when growth slows down.

11. Maintenance & Care Level

Maintenance level is considered easy. Care includes wiping the large leaves with a damp cloth to remove dust, which helps the plant breathe and photosynthesize efficiently. Remove spent flower stalks at the base to encourage new growth.

12. Growth & Propagation

The plant has a moderate growth rate and grows in a clumping habit. Propagation is most easily achieved through division during repotting by gently separating the root clumps into multiple individual plants.

13. Common Problems

The most common issues include brown leaf tips due to low humidity or chemicals in tap water (like fluoride), and yellowing leaves if the plant is overwatered. It can occasionally attract pests like spider mites or mealybugs.

14. Benefits & Uses

Famous for being one of the top air-purifying plants according to NASA studies, it effectively removes indoor toxins like formaldehyde, benzene, and trichloroethylene. It is widely used in home décor, offices, and as a sympathy gift.

15. Toxicity & Safety

The Peace Lily contains calcium oxalate crystals, making it toxic to both humans and pets (cats and dogs) if ingested. Ingestion can cause oral irritation, swelling, and digestive discomfort.
