Nerve plant, botanically Fittonia albivenis, is native to the tropical rainforests of South America, with wild populations documented across Peru, Colombia, Bolivia, Ecuador, and northern Brazil, where it grows as a low, spreading, creeping evergreen groundcover across the deeply shaded forest floor beneath the canopy. It belongs to the acanthus family, Acanthaceae, placing it alongside polka dot plant and Persian shield as relatives, and the genus was named in honor of Elizabeth and Sarah Mary Fitton, two 19th-century Irish sisters whose illustrated 1817 book "Conversations on Botany" helped introduce the science of botany to a young general readership — a meaningful early contribution to popular science education that the genus name has quietly preserved ever since. The species epithet "albivenis" comes from Latin, meaning "white veins," a direct reference to the plant's most visually distinctive feature.

Nerve plant earns both its common English name and its alternate nickname, mosaic plant, from the same striking structural trait: intricate, contrasting networks of veins running across each small, softly textured leaf, resembling either the branching pattern of nerves in the human body or the interlocking tessellation of a mosaic tile pattern, depending on which visual comparison an observer favors. These veins appear in white, pink, or red against a base of rich green leaf tissue, and while Fittonia albivenis is the species most commonly grown, extensive hybridization between two historically recognized varietal groups, Argyroneura (white-veined) and Verschaffeltii (red- or pink-veined), has produced a wide range of modern cultivars with enhanced color intensity and vein density beyond what either original wild form displayed. Popular named cultivars include 'Juanita', prized for its especially bold, deep red venation, alongside a range of selections within the broader Argyroneura and Verschaffeltii breeding lines, giving collectors considerable choice in vein color and intensity well beyond the plain white-veined wild-type species.
