Peace lily

Spathiphyllum wallisii · Houseplant

Glossy dark leaves and white, sail-like blooms make this one of the most popular indoor plants. It tells you when it is thirsty by drooping, then perks up within hours of watering. It tolerates lower light than most flowering houseplants.

When?

Repot in spring when roots fill the pot. Plants that refuse to bloom usually need a brighter spot rather than more fertilizer. Divide large clumps at repotting time.

Step by step

  1. Place in bright, indirect light for the best flowering; low light keeps it alive but with fewer blooms.
  2. Water thoroughly when the top layer dries; empty the saucer after 15 minutes.
  3. Use room-temperature water; if tips brown, try filtered or rested tap water.
  4. Feed every 6–8 weeks in spring and summer with a diluted fertilizer.
  5. Cut faded flower stalks at the base.
  6. Wipe leaves to keep them glossy and dust-free.
  7. Divide crowded plants in spring into clumps with several leaves each.

Common problems

Leaves droopUsually thirst; water and it recovers. If soil is wet, check for root rot.
No flowersToo little light; move closer to a bright window.
Brown leaf tipsDry air, fertilizer buildup or irregular watering; flush the soil occasionally.
Green-tinted flowersNormal as blooms age; cut them off.

Pets

Toxic to cats and dogs. Chewing it irritates the mouth and throat and may cause drooling or vomiting. Keep it out of reach; if your pet has chewed it, contact your vet.
