What it is, and who it suits

A peace lily is a clump of glossy dark leaves with white flag-shaped spathes rising through the middle — both a foliage plant and a flowering one without the upkeep flowers usually demand. Its standout trait is how clearly it signals thirst: the leaves droop dramatically when it needs water and stand back up within an hour of a drink, so almost nobody lets it die of dehydration without warning. It suits first-time plant owners who want a visual cue they cannot miss.

Where to put it, and how much room to leave

Indirect light is enough, and it tolerates shade fairly well — a corner a few metres from a window will still flower, just more slowly than a brighter spot. Avoid direct sun: the thin glossy leaves scorch into brown streaks quickly under strong light. Because it likes high humidity (level 3, tied with the fern for the highest in the foliage group), a bathroom with a window or a kitchen are its two best spots; a dry air-conditioned room is its worst. The canopy reaches about sixty centimetres and spreads about as wide, so leave roughly sixty centimetres of clearance around the pot so the leaves can fan out without bending against a wall.

The year-round rhythm

Roughly every five days, but the most accurate approach is watering by the LEAVES rather than the calendar: as soon as they start to droop slightly, water right away and the plant stands back up within the hour. This is one of the few species where the thirst signal is not something to worry about — it is the plant's own built-in warning system, as long as you do not let that state drag on for days at a time. Ordinary moisture-retentive potting soil is enough, no special mix needed. Trim browned spathes off at the base of the stalk so the plant channels its energy into new blooms. Feed weak fertiliser monthly in the warm season for more even flowering. Repot annually, sizing up once the roots feel cramped.

Which pot suits it

Size M for a normal plant, L once the clump is dense and flowering heavily. A bowl or a medium cylinder both work — no special shape requirement the way a trailing or a strictly upright plant has. Because the dark leaves and white spathes are a strong contrast pair, a pale glaze like Bone or Tan gives both colours a good backdrop; too dark a glaze blends into the leaf colour and loses the contrast that is the plant's best feature. Glazed ceramic suits it slightly better than terracotta, since it holds moisture a little longer, easing the pressure of the five-day rhythm.

Three things that go wrong

Continuous drooping even when the soil feels moist: the roots may already be rotting from earlier overwatering — check the soil, and if it is waterlogged, stop watering for several days. Dry brown leaf tips: usually chlorinated water or air that is too dry — switch to water left out overnight and raise the humidity around the plant. No flowers despite healthy green leaves: not enough light — move it a little closer to a window; even indirect light needs to reach a certain level before spathes will form. Important note: this species is not pet-safe, containing calcium oxalate crystals that cause mouth burning and breathing difficulty if a cat or dog chews the leaves — for a pet household, a snake plant or a succulent is the safer choice over a peace lily.
