About
Fittonia albivenis is a species of flowering plant in the family Acanthaceae, native to the rainforests of Colombia, Peru, Bolivia, Ecuador and northern Brazil. An evergreen perennial, it is notable for its dark green foliage with strongly contrasting white or red veins. It is commonly called nerve plant or mosaic plant. In temperate regions where the temperature falls below 10 °C (50 °F) it must be grown as a houseplant.
How to grow it
The species is used as an ornamental plant that requires fertile soils or substrates based on peat. It is best kept in a moist area with mild sunlight, although it does not demand much light, and temperatures above 55 °F (13 °C). As such, in temperate locations it must be kept under glass as a houseplant.
It must be watered regularly. Without water for a few days, it is known to "faint" but is easily revived with a quick watering and resumes its healthiness. Fittonia albivenis is known to be hard to grow, so it is best bought at a nursery then cared for. Its spreading habit makes it ideal as groundcover.
Uses
The Kofan, Siona and Secoya tribes of the Ecuadorian Amazon use F. albivenis as a treatment for headaches, and muscular pain, its leaves were used by the Machiguenga as a hallucinogen before they were introduced to Psychotria viridis. They are said to "produce visions of eyeballs." The leaves of this species are prepared as a tea in the northwestern part of the Amazon region and used for toothache.
