Peace Lily

The peace lily (Spathiphyllum) is an evergreen tropical perennial in the arum family, native to the rainforests of Central and South America and parts of Southeast Asia. Despite its name, it is not a true lily.

Its striking white 'flowers' are actually a leaf-like bract called a spathe that surrounds a central spadix of tiny true flowers. The plant blooms readily even in low light, making it one of the few flowering houseplants suited to dim rooms.

It is also well known as an air-purifying plant and is forgiving of neglect, though it will wilt dramatically when it needs water — and quickly recover after a drink.

• Leaves: Glossy, dark green, lance-shaped leaves with prominent veins, growing in a clump directly from the soil
• Flowers: White or cream hooded spathe surrounding a pale central spadix; blooms fade to green over time
• Habit: Clumping, stemless rosette spreading from a rhizome
• Size: Commonly 1-3 feet tall indoors
• Behavior: Leaves droop noticeably when the plant needs water

Light: Low to medium indirect light. Tolerates shade but blooms more with brighter (still indirect) light. Avoid direct sun.

Water: Keep the soil evenly moist but not waterlogged. The plant will wilt visibly when dry and bounce back after watering, but repeated wilting stresses it.

Soil: Rich, well-draining potting mix.

Temperature: Prefers 65-80°F (18-27°C) and appreciates higher humidity.

Feeding: Light feeding every 6-8 weeks during the growing season encourages blooms.

Propagation: Divide the clump at the roots in spring.

Spathiphyllum species are native to the humid tropical rainforests of Central and South America, with some species in Southeast Asia, where they grow on the shaded forest floor in moist, rich soil.

They are grown outdoors in warm, frost-free climates (USDA zones 11-12) and worldwide as one of the most common flowering houseplants.

Ornamental: Widely grown for its elegant white blooms and lush foliage, popular in homes, offices, and as a gift plant.

Air quality: Frequently cited in indoor-air studies for filtering pollutants such as formaldehyde, benzene, and ammonia.

Caution: All parts contain calcium oxalate crystals and are toxic to cats, dogs, and humans if chewed or swallowed.
