Fittonia gigantea

Common name: Giant nerve plant · Giant mosaic plant

Fittonia gigantea is an evergreen perennial in the acanthus family (Acanthaceae), native to the Amazonian rainforests of South America. As its name suggests, it is a much larger plant than its better-known relative Fittonia albivenis, reaching roughly 60 cm tall, with bigger leaves marked by the genus's characteristic network of pink to reddish veins. It is grown as a foliage houseplant and in warm climates as ground cover in shady spots, and it shares the nerve plant's love of warmth, moisture, and humidity.

Fun facts

  • The epithet "gigantea" refers to its size relative to F. albivenis — it can be four or more times taller.
  • Its leaves can reach around 10 cm long, far larger than those of the common nerve plant.
  • Like other fittonias, it produces small flower spikes, but it is cultivated almost entirely for its veined foliage.
  • It is sometimes used in paludariums and large terrariums where its scale suits bigger displays.
