Fittonia albivenis

Fittonia albivenis is a species of flowering plant in the family Acanthaceae, native to the rainforests of Colombia, Peru, Bolivia, Ecuador and northern Brazil. 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.
