Light

  1. Low light 3+ mol Copes
  2. Medium light 6+ mol Best
  3. Bright indirect 10+ mol
  4. Direct sun 12+ mol

Peace lilies do well in a well-lit spot out of direct sun and tolerate shade and low light. They flower best with indirect sunlight.

Direct sun: best kept out of it.

On our scale it grows well from about 6 mol/m²/day and holds on down to roughly 0.5 (how these numbers are set).

Will it grow in my window?

Care

Care level: Easy. Water: Keep the soil evenly moist but not soggy, and let it dry slightly between waterings.

Too much direct sun is one cause of brown leaf tips.
