Peace Lily Meaning: What It Symbolizes and When to Give One

People look up the peace lily meaning when they’re choosing a gift for a funeral, an apology or a new home. In gift-giving tradition, the peace lily (Spathiphyllum) stands for peace, purity, renewal and sympathy, its white bloom held above dark leaves like a flag of truce. It’s one of the few plants that suits both sympathy and celebration. This guide covers what it means, when to give one (and when not to), Feng Shui placement, the NASA air-purifying story and why the flowers turn green.

Meanings come from gift-giving tradition; toxicity from the ASPCA.

The Core Meanings

The meanings come from what the plant looks like. Its “flower” is a white spathe, a modified leaf, wrapped around a spike of tiny true flowers; NC State Extension notes that the genus name is Greek for “spathe leaf.”

• Peace and truce. The white spathe reads as a white flag, which is why the peace lily is a common apology gift.
• Purity. A clean white bloom against dark green leaves.
• Renewal. The plant can bloom again and again rather than once, and a living plant outlasts a bouquet, which is why it suits sympathy gifts.
• Healing and resilience. A peace lily droops visibly when dry and recovers after watering, an easy picture of recovery.

Despite the name, it isn’t a lily. Clemson Extension places it in the Araceae family with caladiums, elephant ears, anthuriums and callas. True lilies (Lilium) are a different plant with a different, more dangerous toxicity for cats.

When to Give a Peace Lily (and When Not To)

Condolences. This is where the peace lily is most at home. Cut flowers last a week; a peace lily can keep growing for years, so the gesture stays with the person. Choose one with buds still opening so it keeps flowering after it arrives.

Housewarmings and new starts. Purity and renewal add up to a clean slate. A short note explaining the meaning turns a nice plant into a message.

Offices. It tolerates lower light than most flowering houseplants (Clemson), and its calm associations suit a new job or office opening. For a plant that signals growth and abundance instead, see our monstera symbolism guide.

When not to give one. White flowers are associated with mourning in some cultures, so for a wedding, know the recipients first. And skip it for any home with cats, dogs or young children: the ASPCA lists it as toxic to dogs and cats, and Clemson notes its calcium oxalate crystals can cause toxicity in pets and children if eaten. Our cat-safe plants list has alternatives.

Feng Shui, Placement and the NASA Air Story

In popular Feng Shui writing, the peace lily is a calming plant suggested for bedrooms, meditation corners, home offices and entries. Treat that as tradition, like the language of flowers, rather than measurement. For the plant itself, Clemson says it grows best in bright, indirect light and should be kept out of direct sun, which scorches the leaves.

The air-purifying claim needs context. In NASA’s 1989 Interior Landscape Plants for Indoor Air Pollution Abatement study, plants including Spathiphyllum ‘Mauna Loa’ removed chemicals such as benzene from the air inside sealed test chambers. Iowa State Extension explains that the highly controlled test conditions don’t translate to real homes, and that houseplants have little effect on air quality in the home or office. Buy a peace lily for its meaning and its looks; use ventilation or an air purifier for air quality.

Why Peace Lily Flowers Turn Green

Aging is normal. NC State says the white blooms change to pale green after about 10 days and then stay attractive for at least another month. Clemson describes the same change. If you like, a memorial plant whose blooms go from white to green can read as peace turning into continuing life.

Few or no flowers. Clemson says the plant tolerates low light but grows best in bright, indirect light, so a plant in a dim corner may stay leafy and bloom less. NC State recommends fertilizing at one quarter of the recommended strength and flushing the soil between feedings, because peace lilies are easily over-fed. For yellowing leaves rather than green flowers, see our yellow leaves guide; for repotting, our aroid soil mix suits this aroid.

Frequently Asked Questions

Is a peace lily an appropriate funeral gift?

Yes. It’s one of the most common living plants sent for condolences, and because it keeps growing and can bloom again, it suggests continuing life rather than a bouquet that fades in a week.

What does it mean when someone gives you a peace lily?

Usually peace after a conflict, comfort in grief, wishes for healing, or a fresh start, depending on the occasion.

Is a peace lily safe for cats and dogs?

No. The ASPCA lists it as toxic to both, with insoluble calcium oxalates causing mouth irritation, drooling, vomiting and difficulty swallowing.

Why is my peace lily flower turning green?

It’s normal aging. NC State says the white blooms turn pale green after about 10 days and stay attractive for at least another month.

Do peace lilies really purify the air?

Not noticeably in a normal room. NASA’s tests were in sealed chambers, and Iowa State Extension says houseplants have little effect on air quality in homes and offices.

Is a peace lily a real lily?

No. It belongs to the arum family, Araceae, with anthuriums and callas (Clemson), not to the true lilies, Lilium.
