Nerve Plant
Fittonia albivenis · Acanthaceae
The fittonia, or nerve plant, is a small plant with a big effect: every leaf is covered in a fine network of white, pink or red veins. At no more than 15 centimetres tall it fits on any windowsill or desk and, above all, into terrariums and bottle gardens, where its humidity needs are met automatically. Its famous party trick: when thirsty it collapses dramatically flat — and stands back up within hours of being watered.
- Light
- Bright to semi-shade, no direct sun; also does well under artificial light, for instance in a terrarium.
- Watering
- Regular small amounts, evenly and lightly moist — the small root ball does not forgive days of drought.
- Care level
- Medium

In the trade the nerve plant is usually sold as Fittonia albivenis, with varieties differing in vein colour: white-veined classics such as „Argyroneura“, pink ones such as „Mosaic Pink“ and intensely red ones such as „Red Anne“ or „Forest Flame“. All stay small and grow outward rather than upward — a groundcover in a pot.
As a resident of the rainforest floor, fittonia is used to muted light. It likes a bright to semi-shaded spot but tolerates no direct sun at all, which can scorch the thin leaves within hours. An east or north-facing window is ideal.
Its reputation as a drama queen is well earned: if the small root ball dries out, it drops all its leaves at once. It looks alarming but is reversible — after a drink it usually stands fully upright again. Repeat the performance too often, though, and the plant suffers lasting damage.
The real key to success is humidity. In dry heated air fittonia develops brown leaf edges and dwindles. That is why it is the classic terrarium and bottle-garden plant: in a closed glass with constantly high humidity it practically grows by itself.
Small flower spikes with inconspicuous blooms appear occasionally but cost the plant a lot of energy. We usually pinch them out so the energy goes into the foliage — with fittonia, the leaf is the real show.
Is Nerve Plant toxic to children and pets?

- Non-toxic
The nerve plant is considered non-toxic to cats, dogs and people, making it a good choice for pet households and children's rooms. Larger nibbled amounts can still upset the stomach.
Overview: toxic & non-toxic plants for cats, dogs and children
Care
- 01Bright to semi-shaded spot without direct sun — an east or north-facing window is ideal.
- 02Keep the root ball evenly, lightly moist; the small pot dries out quickly.
- 03Water immediately if the leaves collapse — the plant usually recovers within hours.
- 04Provide high humidity: misting, a terrarium or a spot in a bright bathroom.
- 05Keep warm at 18–26 °C, never below 16 °C, avoid cold draughts.
- 06Feed very lightly once a month from spring to autumn; pinch shoot tips occasionally for compact growth.
Frequently asked
- Is the nerve plant toxic to cats?
- No. The nerve plant is considered non-toxic to cats and dogs, making it one of the best small foliage plants for pet households. As with all houseplants, regular nibbling should still be discouraged.
- My fittonia has collapsed completely — can it still be saved?
- In the vast majority of cases, yes. The sudden collapse is fittonia's typical thirst signal. Water thoroughly or briefly submerge the pot in water — the plant is usually upright again within a few hours. Only leaving it dry for days risks lasting damage.
- Is fittonia suitable for a terrarium or bottle garden?
- It is practically the perfect cast. Constant warmth, high humidity and muted light in a closed glass match its natural habitat on the rainforest floor exactly. In a terrarium it grows denser and more colourful than on any windowsill — only an occasional trim is needed.
- How big does a nerve plant get?
- It stays permanently small at 10 to 15 centimetres tall and spreads in a creeping habit rather than growing upward. That makes it perfect for bowls, table decoration and small flats — and pinching the shoots keeps it compact and dense with little effort.
