About the Spathiphyllum wallisii peace lily

The Spathiphyllum wallisii is the beautifully classic peace lily that you’ve seen many times before, with large, dark green glossy leaves and twice-yearly sophisticated white flowers, it adds a touch of charm to the corner of any room.

The peace lily is easier to care for than most indoor plants, requiring nothing more than typical indoor conditions away from direct sunlight.

This flowering plant will be happy with once weekly watering, typical indoor humidity and indirect, dappled light. All things considered, this is an easy house plant to take care of.

Perfect for beginners, this tropical plant from Colombia and Venezuela proves to be no trouble and will reward you with moderate growth for up to five years, reaching up to 50cm in height and spread, with beautiful, long-lived white flowers twice each year.

Peace Lilies in the House & Office

Placing your peace lily indoors is easy, as it will be happy with most indoor conditions so long as the light isn’t too strong.

Keep your lily within five feet of north, east or west facing windows, and five or more feet from south facing windows, moving it nearer or further away depending on both how strong the light is and how your plant reacts. Burning leaves, or browned edges suggest you should move the plant further from the light.

While this plant will be happy with most indoor climates, you should try to increase the humidity to above 50% for optimal growth, but it will survive a humidity level of 40%.

Interestingly, studies from NASA on the ability of certain plants to remove contaminants from the air. Alongside other air purifying plants, they concluded that the peace lily was among the best plants to improve air quality indoors, making this an excellent option for homes and offices.

Spathiphyllum wallisii Care

Light: Your plant should be kept away from direct light and will enjoy bright, indirect light. Consider that this plant would see light dappled by larger plants and trees in the wild, so will usually never experience very bright and direct sunlight. Keep your plant within 5 feet of bright windows, except for south-facing windows where it should be kept 5 feet or further away. If the leaves begin to burn, move your plant further away.

Soil: A moist but well-draining potting mix should be used to ensure that your plant doesn’t develop root rot. Mixing regular potting soil with perlite, orchid bark or gravel will increase drainage.

Watering: When the top inch of soil is dry, the plant should be watered. You should be able to limit watering to once per week, but should increase watering if the plant ever begins to droop.

Humidity: While peace lilies will survive in most indoor climates, a humidity of 40% is an ideal minimum, and a humidity of 50% or more is ideal for the best and fastest growth. You can raise the humidity by misting the plant daily, grouping it together with other plants or by sitting the pot on top of pebbles and water.

Feeding: Your spathiphyllum wallisii won’t feed too heavily, so you can limit plant food to just once every 6-8 weeks during spring and summer, with a typical liquid houseplant food.

Temperature: Typical indoor temperatures of at least 18°C / 64°F are fine for your plant, but it will be happy up to 28°C / 82°F. Don’t allow the temperature to approach freezing levels as this will begin to cause damage.

Ailments: Browning leaves suggest that the humidity level is too low and / or your plant is receiving too much sunlight. If the plant receives quite bright and direct light, move it further from the window, otherwise try increasing the humidity levels. Peace lilies can also become infested with aphids or spidermites, which can be removed by spraying daily with either an oil and water solution, or a detergent and water solution.

Where To Buy Spathiphyllum wallisii Online

The Spathiphyllum wallisii peace lily is a fairly common houseplant that you should find readily available at most garden centres, plant shops and online stores.

Online, you should always make sure to check reviews and feedback, as well as return / refund policies. Always buy from a seller with positive ratings and a reliable history.

Regardless of where you buy your plant from, don’t settle for a damaged, infected or infested plant. If you are at all unhappy, you should complain and start the process to return your plant. If you do decide to keep an infected or infested plant, do not introduce it to your other plants until you are confident that it has been successfully treated.


Where should I place a peace lily in my house?

An ideal location would be within a few feet of a window that doesn’t face south. This will give your plant indirect light for most of the day, which is ideal. While it can survive humidity levels of 40% or more, the more the better. A kitchen or bathroom often has the highest levels of humidity in the home, so these may be suitable.

How do I make my peace lily variegated?

It is not possible to take a regular peace lily and variegate it. Variegation is a genetic trait and plants either are or are not variegated from the moment they sprout from the seed. If you want to increase the variegation of a variegated plant, you can provide it with more light, as this usually brings out more and stronger flecks and stripes of white and cream.

Should I cut the brown tips off my peace lily?

While opinions on this topic do sometimes clash, we recommend to not cut browning leaves from a plant until the entire leave has browned fully, unless the leaf is clearly infected by a disease or infested by a parasite. Plants will pull water and nutrients from older leaves, but if they are removed too early then the plant is unable to retain those nutrients, which is why we recommend to wait until it has finished.
