A low, spreading plant netted with white or pink veins, the nerve plant demands bright indirect light, soil that never dries out, and humidity higher than most rooms can offer. It is famous for fainting — collapsing flat the moment its soil goes dry — then reviving within hours of a drink. Dry air is its real enemy, which is why it thrives in a terrarium or bathroom.

Care at a glance

Light
Bright, indirect light or light shadePlenty of light keeps the veining vivid, but direct sun scorches the thin leaves. It also does well under artificial light.
Water
Keep the soil constantly, lightly moist — never let it dry outWater as soon as the surface starts to dry; if it dries fully the plant dramatically wilts, though it usually recovers after a soak.
Soil
Moisture-retentive, peat-free houseplant mixA coir-based compost with a little perlite holds the steady dampness it needs without turning to mud.
Humidity
Craves very high humidity, 60–90%Ideal for a terrarium, propagator or steamy bathroom; ordinary dry rooms quickly crisp the leaves.
Temperature
18–27 °C (64–81 °F)Keep above 15 °C (59 °F); it hates cold draughts and sudden chills.
Difficulty
ModerateEasy in a humid, enclosed setting; tricky in a dry open room where it constantly wilts.
Pets
Non-toxic to petsNon-toxic to cats and dogs (ASPCA), a safe little plant for pet households and terrariums alike.

Propagation

Nerve plants root very readily from stem-tip cuttings. Snip a 5–8 cm tip just below a node, strip the lowest leaves, and either stand it in water or push it into damp mix. Kept warm and humid — a covered propagator or sandwich bag helps enormously — it roots within a couple of weeks.

Because the plant spreads along the soil and roots at its nodes, you can also simply divide a full pot into rooted sections at repotting. Taking cuttings regularly is worthwhile anyway, since older plants grow leggy and bare at the centre and benefit from being refreshed.

Common problems

  • Sudden, dramatic wilting and collapse

    Likely cause: The soil has dried out — Fittonia faints theatrically the moment it runs short of water.

    Fix: Water thoroughly straight away; it usually perks back up within a few hours. Keep the soil from drying out to prevent repeated fainting, which weakens it over time.

  • Crispy, shrivelled leaf edges

    Likely cause: Humidity too low for this rainforest-floor plant in a dry, open room.

    Fix: Raise humidity sharply — move it to a terrarium, propagator, or bathroom, or run a humidifier nearby.

  • Faded, washed-out veining and leggy growth

    Likely cause: Too little light, so the colours dull and the stems stretch.

    Fix: Move it to brighter indirect light and pinch the tips to keep it bushy; take cuttings to replace a bare, leggy plant.

Frequently asked questions

Why does my nerve plant keep collapsing flat?

That dramatic collapse is the nerve plant's famous response to dry soil — it faints the instant it runs short of water, then usually revives within a few hours of a thorough drink. The occasional faint is survivable, but repeated wilting stresses the plant, so the real fix is to keep the soil consistently moist so it never reaches that point.

Is a nerve plant good for a terrarium?

Excellent — it is one of the classic terrarium plants. Its love of constant moisture and very high humidity, which makes it tricky on an open shelf, is exactly what a closed terrarium provides. Its small size and vivid veining suit the enclosed space well, though you will need to trim it occasionally to keep it in bounds.

How do I keep a nerve plant alive in a dry room?

Boost the humidity by any means you can: a pebble tray, grouping it with other plants, a nearby humidifier, or growing it under a cloche or in a glass bowl. A steamy bathroom with good light also suits it. Without extra humidity in a dry room, the leaf edges crisp and the plant struggles however carefully you water.

Why are the leaves on my nerve plant shrivelling at the edges?

Shrivelled, crispy edges almost always mean the air is too dry for this rainforest-floor plant, sometimes combined with the soil drying out between waterings. Lift the humidity well above what most rooms offer and keep the soil lightly and constantly moist, and the new leaves should come through smooth and unmarked.
