Fittonia

Fittonia (or nerve plant or mosaic plant) is a genus of evergreen perennial flowering plants in the acanthus ('bear’s britches') family, Acanthaceae. The genus is native to tropical and subtropical forested areas in northern and western South America, mainly Peru.

The most commonly cultivated species is F. albivenis and its range of cultivars. They are low-lying, forest floor plants, typically only growing between 10–15 cm (4–6 in) tall, without the 5-10 cm (1-4 in) tall flower stalks. The main feature of the species is its lush, green foliage, streaked with veins of white to deep pink, depending on cultivar; this veining earns the plant its common name of 'Nerve-Plant', as the "network" of vessels appears to resemble the layout of a nervous system. The plants also possess a short fuzz on their stems, like other acanthus family genera. Small buds may appear after a time where the stem splits into leaves.
