Fittonia, commonly referred to as Nerve Plant or Mosaic Plant, is a captivating genus of tropical plants renowned for their striking, veined foliage. The genus includes a variety of species, each boasting unique leaf patterns and colors. Fittonia plants are prized for their ornamental value and are popular both as houseplants and terrarium specimens.
Fittonia prefers bright to moderate indirect light. Direct sun bleaches and scorches the distinctive veined leaves. It tolerates lower light well, though growth slows and the vein contrast may diminish. A north or east-facing window, or a spot 1–2 metres from a bright window, is ideal. Excellent for terrariums.
Keep the soil consistently moist — Fittonia wilts dramatically and rapidly when it dries out, giving it the nickname 'drama queen'. However, this wilting is a useful watering signal: the plant revives fully within an hour of watering if not left dry for too long. Do not let it sit in standing water. Use room-temperature water.
Use a moisture-retentive mix with good drainage: 60% peat or coco coir, 40% perlite. The fine root system prefers loose, aerated soil. Slightly acidic pH (5.5–6.5).
Optimal 18–26 °C; minimum 15 °C. High humidity (60–80%) is essential — Fittonia is a tropical rainforest native and thrives in enclosed humid environments. It is one of the best terrarium plants due to its humidity requirement and compact size.
Feed every 2–4 weeks during spring and summer with a balanced liquid fertilizer at quarter strength. Fittonia is a light feeder — excess fertilizer causes root burn.
Pinch off stem tips regularly to encourage a compact, bushy habit. If the plant becomes leggy, cut it back hard in spring — it recovers quickly. Repot annually in spring as the shallow root system fills small pots quickly.
The most common method for propagating Fittonia is by stem cuttings. This involves taking cuttings and rooting them in water or soil. Ensure the parent plant is healthy before proceeding.
Another method for propagating Fittonia is by division, which involves separating the plant at the roots and replanting each section.
