The peace lily is the common name for different species in the genus Spathiphyllum. It is also called the spathe flower or the white-sail plant.
This pretty plant likes to grow in the shade and has a pleasant scent. It’s one of the most popular houseplants for a good reason.
Young peace lilies are fully grown in three to five years, by which time they have developed dark green leaves and their distinctive white flowers.
The big white petal that looks like a flower and is shaped like an upright leaf is actually a huge spathe.
This wide stem has a lot of small flowers that can grow to be 6 inches long and 4 inches wide. Both the spathe and the spadix (the inner rod that sticks out) do a great job of cleaning the air around them.
This is one of the many reasons why peace lilies are great indoor plants. Keep your peace lily out of reach of kids and dogs because this species is dangerous.
Plant your indoor peace lily in potting soil that can be used for anything and cover it with sphagnum moss to keep water in.
Once a week, or whenever the top two inches of soil feel dry, water this plant. During the summer, when the plant is growing, you may need to water your peace lily more often, but it is usually easy to take care of and doesn’t take much time.
The beautiful, fragrant flowers could last up to six weeks. Even the strongest white peace lily blooms will turn light green in the end.
If you like white flowers, cut them off when the petals turn green so you can enjoy the plant’s leaves until it blooms again.
Best Growing Conditions for Peace Lilies
Even though these plants do well in shaded areas because they don’t need much light, they still need a lot of sun to grow. Shadows here and there are fine, but moderate, indirect light is better (so place yours near a north- or east-facing window if possible).
For your peace lily to bloom, it will need more light. Remember that a peace lily that receives at least a few hours of strong, indirect light will bloom the most. Make sure your plant isn’t in direct sunlight, which could burn its leaves.
This plant needs to be watered often to stay healthy. Your peace lily will let you know when it needs more water. When this plant is thirsty, its leaves start to droop right away.
They usually get back to their healthy, upright shape the same day they are watered. The fact that the leaf tips are black also shows that this species needs more water.
Because this plant is native to the rainforest, it should be kept at temperatures above 65 degrees.
Choose a place that doesn’t have cold drafts. Since peace lilies come from the tropics, keep the air around your plant moist. One way is to put the pot on a tray with stones and water to make it humid.
When water evaporates, it makes the air around your plant more humid. You can also grow a peace lily in your bathroom, where the steam from your shower or tub will help it grow.
Types of Peace Lilies
For example, the Mauna Loa cultivar is known for its huge number of leaves and flowers that may bloom all year.
It may also grow up to 3 or 4 feet tall. Spathiphyllum wallisii is the only peace lily that is not a hybrid. It grows to only 1 foot tall and is a good choice for a smaller peace lily.
How to Propagate Peace Lilies
Peace lilies can’t be grown from stem or leaf cuttings, but they can be spread easily by dividing them at any time of the year.
Even though a good gardener could grow these plants from seeds, it would take a long time for them to bloom. Here’s how to spread your peace lily plant to make more of them:
Step 1: Put fresh potting soil in a new pot that is no bigger than 6 inches in diameter.
Step 2: Gently take the mother plant out of its pot and loosen the soil around its roots.
Step 3: Use a clean, sharp garden blade to cut any roots that connect the leafy piece to the mother plant.
Depending on how big the mother plant is, you may be able to cut more than one clump.
Step 4: Put the new peace lily in the pot with the mother plant.
Step 5: Water the new plant and put it somewhere warm with a lot of bright, indirect light while it gets used to its new pot.
Keep the soil moist but not soaked for a few weeks, until the plant’s roots are established. Take care of the new plant like you always do.
Common Problems With Peace Lilies
Peace lilies are easy to take care of, which makes them a great choice for people who have never had a plant before. But, like any other houseplant, there are a few things that can go wrong with its growth.
When grown in the dark, peace lilies are less likely to bloom and are more likely to get diseases like powdery mildew.
Fungus infections can be stopped by giving the plant enough light and watering only the soil, being careful not to splash the leaves. In some cases, you may need to use fungicide to make your plant healthy again.
Leaves Dying or Falling
As with many popular houseplants, some peace lily leaves will die on their own. If you notice that the health of the leaves is getting worse, you should cut off the dead ones.
If you don’t do this quickly enough, pests will start eating not only the dead leaves but also the healthy ones.
If the tips of your plant’s leaves are turning yellow or it looks like it’s wilting, put it in a new pot with new soil and cut back on how much water it gets.
Potting and Repotting Peace Lilies
In late winter, repot the plant when it starts to grow new branches before the spring growth season. If you want to repot your plant, just go one size up.
If the plant can fit in a 10-inch pot, it won’t need bigger pots in the future. Instead, start trimming it and adding new soil to the same container.
Choose a pot with enough holes for the water to drain. Repotting is also a great time to divide your peace lily into two to make a second plant.
You can grow peace lilies in water without any soil if you don’t want to use soil. Put glass stones or pebbles in the bottom of the vase to keep the roots of the plant below the waterline and the stems and leaves above it. This will keep the green parts of the plant from dying.
How to Get Peace Lilies to Bloom
If they are planted right, most peace lilies bloom twice a year, in the spring and the fall. The flowers usually last for about six weeks, but they can last as long as two months. Most of the time, your peace lily won’t bloom because it doesn’t get enough light.
If your plant isn’t close enough to a window, it might not bloom if you grow it in a place with low light.
Your peace lily might not bloom in direct sunlight or dark rooms because the strong light could burn its leaves and hurt the plant.
If you change how much light your peace lily gets, you might not see the results until the next time it blooms.
Once the plant has bloomed, you can remove dead flowers by cutting them off at the base of the flower, above any healthy leaves. This is called “deadheading.”
Are Peace Lilies Hard to Take Care Of?
Peace lilies are easy-care plants that smell nice. The most important things to do to grow peace lilies are to water them regularly, keep the temperature above 65 degrees, and give them medium to dappled indirect sunlight.
Are Peace Lilies Perennials?
Peace lilies are perennial plants with green leaves that bloom white flowers in the spring and fall.
How Fast Do Peace Lilies Grow?
Your peace lily could grow from 1 to 6 inches per year, and it could be fully grown in three to five years.
Can Peace Lilies Grow Outside?
Since peace lilies are from the tropics, most of them are kept as houseplants to keep the house warm in the winter. However, if you live in USDA Hardiness Zones 10 through 12, you can grow them in the ground outside.
