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. 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 it must be grown as a houseplant.
Description
Fittonia albivenis is a creeping evergreen perennial growing to high, with lush green, ovate leaves, 7 to 10 cm long, with accented veins of white to deep pink and a short fuzz covering its stems. Flowers are small with a white to off-white color.Cultivation
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. 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.
Numerous cultivars have been selected, falling into two cultivar groups, the Argyroneura Group with silver to white veins, and the Verschaffeltii Group with pink to red veins, both of which have gained the Royal Horticultural Society's Award of Garden Merit.
