Peace Lily

Spathiphyllum wallisii

A plant that visibly wilts when thirsty and springs back within hours. Ideal for the corners of your home that you thought were too shady for anything alive.

Common problems

What usually goes wrong.

Dramatic wilting

The plant is thirsty. Water thoroughly - leaves usually recover within 4 hours. If this happens every 3 days, the pot is too small; if once every 2 weeks, you have the rhythm right.

Yellow leaves

Usually overwatering, or too much light. Peace Lilies prefer to dry slightly and hate direct sun. Move away from the window if the leaves are pale-yellow.

Brown leaf tips

Tap water fluoride or low humidity. Switch to filtered water, or leave tap water out overnight before using. A pebble tray helps.

No flowers

Not enough light. Peace Lilies flower once mature (2+ years) and only in adequate indirect light. Move closer to a bright window - bright enough for you to read comfortably.

Peace Lilies are honest. If yours is drooping, water it. If it's yellow, water it less. If it's not flowering, give it more (indirect) light. There's rarely a third factor - resist the urge to over-diagnose.
