Light

Bright, indirect light. Too little light = leggy, sparse; prolonged direct sun scorches.

Moisture and substrate

Likes moist-to-wet; use bottom watering or a shallow tray, even semi-aquatic. Moisture-retentive but draining mix, pH 5.5–7.5.

Temperature, humidity, feeding

High humidity, 20–28°C. Feed sparingly, diluted monthly in growing season.

Propagation

Division or cuttings root in weeks (faster in water).

Common problems

Yellowing: over/underwater or nutrient; leggy: low light; algae: improve circulation.

Desktop appeal: Dense round leaves, soothing; water-grown in glass is tidy; coin-shaped prosperity meaning.
