I Love Peace Lilies

“Ren, what would be the best houseplant for someone who kills every plant I touch?”

I love all of my houseplants, but to be fair, I do have some favorites. My Dwarf Banana Tree and my two Monsteras, and my Peace Lily are definitely in the top 10. It is hard to pick, though, because I have over 200 houseplants and I love them all for different reasons.

About the Peace Lily

Scientific Name: Spathiphyllum

  • The peace lily is a flowering plant that is native to the tropical regions of South America. This low-maintenance houseplant can reach up to four feet tall and has large, dark green leaves with white flowers. The peace lily gets its name from the spiky yellow “spathe” that protrudes from the center of the white flower.

Caring for a Peace Lily Plant

Watering:

  • Peace Lilies like to be watered regularly, but not constantly. You should give your plant about one cup of water per week, either all at once or divided up into multiple watering sessions.
  • Be careful not to over-water peace lilies, as this can cause root rot. You will want to choose a container with drainage holes and place a saucer under to catch the water that drains out. If your Peace Lily plant starts to wilt, check the roots to make sure they are firm rather than soggy. If they’re soggy, you’re overwatering or the soil isn’t able to drain. You will want to replace some of the damp soil with new soil so that the roots can dry out a bit.
  • These plants will tell you they are thirsty when they start to droop a little. As seen in the picture below, this is what a Peace Lily will look like when it needs water.

Lighting:

  • Peace Lilies need bright but indirect light to thrive.
  • Place your plant near a window that gets plenty of natural light, but make sure it is not in direct sunlight or the leaves will scorch.
  • I have mine in my home office that has one north-facing window.
  • Peace Lillies need enough light to bloom year-round, but they will bloom a lot more during the spring and summer

Soil:

  • Peace lilies grow well in humid environments, so you should use a potting mix that is high in organic matter and moisture retention.

Fertilizing:

Temperature:

  • Peace Lilies prefer cooler temperatures, so keep your plant in the 65-80º degrees Fahrenheit range.
  • It is important to keep your plant away from dry heat, cold drafts, and/or drastic changes in temperature.
  • Peace lilies are not cold-hardy plants, so they can only be grown outdoors in warm, humid climates (USDA Zones 10, 11). I live in Wisconsin Zone 5B and my Peace Lily thrives indoors.

What is plant root rot?

I have a blog post all about how to get rid of root rot HERE.

Can Peace Lilies be Grown in Water?

Yes, peace lilies can grow in water alone; they are often gifted in vases without any soil. The base of the plant should be set above the waterline, either by a specially-made insert or a layer of tiny river stones.

This allows the roots to grow into the water while preventing the base of the plant and its leaves from getting damp, which can cause rot.

  2. Fill a 6-inch pot with fresh potting soil that is moist.
  3. Immediately plant the clumps in the soil and water thoroughly.

Common Peace Lily Problems and Solutions

  • Shriveled, dry leaves: This is caused by insufficient humidity levels or the plant needs to be watered.
  • Brown leaf tips: Are often caused by over-watering. Remember to keep the soil moist and not soggy.
  • Brown leaf tips, streaks, or spots: You may see this if your plant is placed in direct sunlight for too long. You will need to move the plant into an area with filtered light if this is the case.
  • No blooms: Although the Spathiphyllum can thrive in low light conditions it will very likely not produce any flowers in such conditions. Move it into a well-lit area or purchase a plant light. We have ours on our sun porch in front of a south-facing window that gets great morning light. We supplement its light with a plant light during the winter when there are fewer hours of daylight. Be sure to set a timer (no more than 4 hours at a time) to avoid burning the foliage.
  • Dramatic wilting or drooping: As pictured above, this will happen if the plant is left to dry out too much from lack of watering. Water the plant right away and the leaves will pop up quickly.

Reasons Why I Love the Peace Lily Houseplant 

Peace Lillies can thrive in low light!

This plant is a low-light plant meaning that it does not need direct sunlight. They prefer to have bright indirect light from a window that is nearby.

They can be placed in a room with a window, but the farther away from the window they are, the less likely the flowers will bloom. They can become “leggy,” which means they will have more green leaves and fewer flowers.

Peace Lilies are hearty and will survive in your home year-round! Even in the chilly winters in the midwest! Peace Lilies will flourish indoors at 65-85° temperatures.

Peace Lillies bloom beautiful blooms! At times, the leaves on the Peace Lily can collect dust. Wipe the leaves with a wet sponge or cloth. As flowers and leaves start to yellow and die, just cut them at the base.

There is white pollen that can fall on the leaves. When these spikes appear, cut them off to avoid this pollen from covering the leaves. This will allow the beautiful spathes to show, the flowers to flourish, and add charm to your home.
