Nerve plant (Fittonia spp.) is a spreading evergreen perennial with delicately veined, deep-green leaves. Although the most popular vein color is silvery-white, you can also readily find varieties with veins in red, pink, white, and green. Nerve plant is a low-growing creeper that is a perfect fit for terrariums or bottle gardens. Fittonia typically grows to a height of 3 to 6 inches with a trailing spread of 12 to 18 inches.
As beautiful as it is, Fittonia is somewhat temperamental and tricky to grow as a houseplant. It requires very high, constant humidity, such as found in a terrarium, and cannot tolerate stagnant conditions. Nerve plant is also sensitive to strong, direct sunlight and will quickly suffer from leaf burn.
