Fitonia

Normally grown as a houseplant, nerve plant (Fittonia spp.) is a spreading evergreen with delicately veined, deep-green leaves. Although the most popular vein color is silvery white, you can also readily find varieties with veins in pink, white, and green. Nerve plant is a low-growing creeper that is a perfect fit for terrariums or bottle gardens. In USDA hardiness zone 11, nerve plant is sometimes grown as a creeping ground-cover in filtered sun locations. Fittonia typically grows to a height of 3 to 6 inches with a trailing spread of 12 to 18 inches. Although the plant rarely flowers when grown as an indoor houseplant, it does occasionally bloom with insignificant reddish or yellowish-white spikes.
