Fittonia albivenis is a relatively common ornamental taxon, grown especially as a houseplant for its striking foliage. The leaves inspire many common names, including mosaic-plant, nerveplant, silver fittonia, silver netleaf, silver-nerve and silver-threads. The epithet albivenis breaks down to "white-veined", while argyroneura means "silver-nerved". Fittonia, however, was named in honour of two 19th-centurty Irish botanical writers: Elizabeth and Sarah Mary Fitton. Google Books has at least one of their texts available online: Conversations on Botany, written as a textbook for children to learn about plants and the Linnaean system.
The species is native to much of western and central South America, where it is a low-growing, creeping perennial of tropical rainforest floors. Unsurprisingly then, to successfully grow it indoors requires temperatures above 12°C (55F), moderate watering with high humidity and filtered or low sunlight. Additional growing details are available via Missouri Botanical Garden: Fittonia albivenis Argyroneura Group and the Royal Horticultural Society: Fittonia albivenis Argyroneura Group. The RHS has given this Group the Award of Garden Merit (as a refresher, a horticultural group is a "collective name for groups of plants, usually cultivars within a genus that all have similar characteristics"). A second Group is also broadly available in the trade, Fittonia albivenis Verschaffeltii Group, where the leaf veins are pink or red instead of white.
