The Peace Lily (Spathiphyllum) is a tropical plant that grows wild throughout much of Venezuela and Columbia where it thrives in the humid, shady environment.

In the 1870s, it gained popularity as a houseplant throughout Europe.

Recently, the U.S. NASA Clean Air Study was released which examined the best plants for purifying the air and making an abundance of oxygen. The research revealed that the Peace Lily was a leader in removing air pollutants.

Growing the Peace Lily Indoors

As a houseplant, the Peace Lily is remarkably easy to grow. It tolerates lack of care and continues to thrive.

Due to the plant’s popularity, many cultivars have arisen.

Currently, there are about 30 varied species available. The most common include the Piccolino, the Little Angel, Patricia, Domino, Picasso, and the Jetty. They all produce lush dark green leaves and white flowers that resemble the white flag of peace (thus the origins of the plant’s name).

Peace Lilies can survive outdoors in tropical locations where there is ample humidity and warmth. However, in most parts of the world, they are grown as indoor plants.

Peace Lily Maintenance

Light and Location

In the rainforest, where the Peace Lily naturally grows, it receives only dappled sunlight due to the dense canopy of trees.

In a home environment, the peace lily can thrive in low light situations where there is partial shade. If you are concerned about the level of light then you can always add a grow light, but in most situations, the Peace Lily does well when placed by a window.

It is a favoured plant for a desk because it will tolerate fluorescent lights well.

Temperature

As mentioned, the Peace Lily does not tolerate cold well. Ideally, the plant thrives when the temperature hovers from 18 to 27 degrees Celsius (65 to 80 degrees Fahrenheit).

Place the plant in an area where it is just exposed to drastic changes in temperature or drafts.

Also, avoid putting the plant in a location where a heater frequently blows on the foliage during the winter months.

Peace Lily Watering

Peace Lilies thrive when watered frequently but do let the soil dry out between watering. Also, make sure that the pot has ample drainage holes, so the soil does not become overly soggy.

The Peace Lily does not tolerate wet roots well so don’t let the pot sit in water for an extended amount of time or the roots of the plant could start to rot.

When to Water a Peace Lily


If the foliage start to droop, the Peace Lily is in desperate need of water.

If the foliage of the plant starts to droop or wilt, then the Peace Lily is in desperate need of water. Avoid letting the plant reach the stage of wilting before you water because this causes undue stress on the plant and can weaken its overall growth and ability to survive.

Ideally, water about once a week will suffice to keep the Peace Lily healthy and happy.

You can also spritz its leaves with water during the summer months to help keep the plant hydrated and remove any accumulation of dust and debris from the surface of the leaves to keep them looking pristine and green.

Care of Peace Lily Plant

Fertilizing

During the spring and summer months, the Peace Lily will enjoy an application of organic fertilizer. The fertilizer will help encourage the plant to bloom.

Try to avoid using chemical fertilizers because the Peace Lily has shown that it is sensitive to certain chemicals which can negatively impact the plant’s growth and health.

Repotting

When you start to notice your plant’s roots showing across the surface of the soil then it might be time to transplant the plant to a larger container.

Repot the peace lily in a container that is one size larger than its previous container for best results. All peace lilies do well in a pot that is at least 25 centimeters.

Propagating the Peace Lily

Propagate the peace lily via stem or leaf cutting. You can propagate the plant any time of the year. Some gardeners also gather seeds but if you decide to propagate with seeds, remember that it will take several years for the plant to grow large enough to bloom.

How to Get the Perfect Bloom

Peace Lilies produce a flower or flowers twice a year – in the spring and fall.

However, they do require the correct conditions to flower. The blooms appear on a long stem with a spathe and tower above the plant like a peace flag.

To ensure flowering, make sure your Peace Lily receives at least six hours of sunlight per day. Water at least once a week (do not let the plant wilt or it might not produce flowers) and also mist its leaves frequently to maintain a consistent humidity level.

It’s not unusual for your Peace Lily to not bloom the first year that you own the plant. It takes time for the Peace Lily to acclimatize your home’s environment but eventually the plant will produce flowers as long as it receives adequate light and water.

Growing Peace Lilies in Water

Some people abstain from using soil and grow Peace Lilies in water alone such as in a vase with a fish to create an aquaponic environment. Suspend the Peace Lily so the top portion of the plant is above the water line and the root system is floating in the water. You can use a layer of small river stones for support. The Peace Lily will grow well in such a fashion as long as you keep the base and leaves of the plant from getting constantly wet which could lead to rot.

Peace lilies are a remarkably hardy and easy-to-grow houseplant. The plant will live for years with minimal care while creating an abundance of clean oxygen.
