Fittonia albivenis is a species of flowering plant in the family Acanthaceae, native to the rainforests of Colombia, Peru, Bolivia, Ecuador and Brazil. A herbaceous plant, it is notable for its dark green foliage with strongly contrasting veins.
The nerve plant, or Fittonia argyroneura, from the Acanthaceae (Acanthus) family, is a tropically found plant with striking leaves of pink and green, white and green, or green and red. Foliage is primarily olive green with veining taking on the alternate hue. For specific color characteristics, look for other Fittonia nerve houseplant, such as F. argyroneura with silver white veins or F. pearcei, the carmine pink-veined beauty. Named for its 19th century discoverers, the botanists Elizabeth and Sarah May Fitton, the Fittonia nerve plant does indeed flower. The blooms are insignificant reddish to white spikes and tend to blend in with the remainder of the foliage. The blooms of the nerve plant are rarely seen when it is grown indoors as a houseplant.
