Normally grown as a potted houseplant, the nerve plant (Fittonia spp.) is a spreading evergreen perennial with delicately veined, deep-green, ovate leaves. Although the most popular vein color is silvery-white, you can also readily find nerve plant varieties with veins in red, pink, white, and green. Fittonia typically grows to a height of 3 to 6 inches with a trailing spread of 12 to 18 inches. Although the slow-growing plant rarely flowers when grown as an indoor houseplant, it does occasionally bloom with insignificant reddish or yellowish-white spikes. In the right zone, the plant is sometimes grown as a creeping ground cover in filtered sun locations. As beautiful as it is, Fittonia is somewhat temperamental and tricky to grow as a houseplant. It requires very high, constant humidity, such as is 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.

Introduction to the Nerve Plant
The Nerve Plant, scientifically known as Fittonia albivenis, is a popular houseplant celebrated for its stunning, intricately veined leaves. These tropical beauties, native to the rainforests of South America, bring a touch of elegance and vibrancy to any indoor space. The Nerve Plant is also known by common names such as mosaic plant, fittonia, and painted net leaf. It belongs to the Acanthaceae plant family.
Common Names and Botanical Classification
The Nerve Plant, also known as the mosaic plant, fittonia, or painted net leaf, is classified botanically as Fittonia albivenis, belonging to the Acanthaceae plant family. This tropical perennial originates from the lush rainforests of South America.
Plant Characteristics and Growth Habits
Nerve plants are spreading but slow-growing, compact evergreen perennials. In balmy tropical conditions, a nerve plant can grow as creeping ground cover in shady areas with filtered light, but it’s usually grown as a house plant as it is very sensitive to low temperatures. As a houseplant, nerve plant can be placed in small pots on tabletops, bookshelves, and desks in homes or offices in indirect, bright light. The plant typically grows to a height of 3-6 inches with a trailing spread of 12-18 inches.
Nerve Plant Care
Light Requirements
Nerve Plants thrive in bright, indirect light. Direct sunlight can scorch their delicate leaves, so it’s best to place them near a north or east-facing window where they can enjoy filtered light. They can tolerate lower light conditions, but their growth may slow, and their vibrant colors might fade. Nerve plants do well under fluorescent lights or near diffused light coming in from a sheer curtain. They can also be placed in bathrooms with low lighting.
Watering Needs
Nerve Plants prefer consistently moist soil but are sensitive to overwatering. Water them thoroughly when the top inch of soil feels dry to the touch, ensuring excess water drains away to prevent root rot. They enjoy high humidity, so misting the leaves regularly or placing the pot on a humidity tray can help maintain the moisture they crave. During winter, reduce watering frequency slightly to match the plant’s slower growth rate.
Soil Mix and Potting
A well-draining potting mix is essential for Nerve Plants. A blend of peat moss, perlite, and standard houseplant soil works well. This mix retains moisture without becoming waterlogged, providing the perfect environment for healthy root development. Any conventional potting soil mix and standard houseplant pot with bottom drainage holes will work for Fittonia. Repot annually in spring or early summer, always using fresh potting soil to prevent soil compaction and waterlogging.
Temperature and Humidity Preferences
Nerve Plants thrive in warm, humid conditions, ideally between 60–80°F (15–27°C). They are sensitive to cold drafts and sudden temperature changes, so keep them away from open windows, doors, and air conditioning vents. To boost humidity, consider using a room humidifier or grouping your Nerve Plant with other humidity-loving plants. Regular misting will keep the plants from drying out, and in arid climates or during the dry months of winter, using a room humidifier may be helpful.
Nerve Plant Fertilization
To keep your nerve plants (Fittonia spp.) thriving, it’s important to provide them with the right nutrients during their growing season. During the spring and summer months, when nerve plants are actively growing, feed them weekly with a weak solution of a balanced liquid nerve plant fertilizer. A nerve plant feeding regimen using a 5-5-5 nerve plant nutrients formula diluted to half strength works well.
As the cooler months of fall and winter approach, reduce the frequency of fertilizing to match the plant’s natural slowdown in growth. Providing the right balance of nutrients at the appropriate times will help your nerve plant maintain its lush, vibrant appearance indoors.
Pruning and Maintenance
Regular pruning helps maintain the compact, bushy shape of Nerve Plants. Pinch back the tips of the stems to encourage branching and remove any yellow or dead leaves to keep the plant looking its best. Nerve plants require little pruning when grown in the right conditions because this keeps the plant looking full. Pruning is necessary when the nerve plant gets too leggy, and can be done by pinching back the stems about a quarter of an inch above its leaf node.
Repotting
Repot the nerve plant every one to two years, in the spring, to help refresh the soil and provide more room for growth. Select a container with drainage holes that is one size bigger (no more than 2 inches wider in diameter) than the previous pot, and use fresh, well-draining potting mix. Place the plant so the top of the root ball is level with the potting mix and gently press in around the plant.
Nerve Plant Propagation
Nerve plants propagate readily from stem-tip cuttings, taken in late spring or early summer, at the same time you repot the plant. Using clean, sharp garden shears, make stem-tip cuttings at an angle, making sure to include at least two growing nodes on the bottom of the cutting to obtain the best results. Bury the bottom of the cutting in a pot filled with a peat-based soil mix. Use of a rooting hormone is not usually necessary, but if your conditions are less than ideal (too dry or too cool), rooting hormone might increase your chances of success. Keep the soil moist but not wet, and expect roots to sprout within two to three weeks.
Seed Propagation
While nerve plants can also be propagated from seeds, this method is less effective compared to stem cuttings. Seed propagation can be more challenging and have lower success rates than vegetative propagation.
Nerve Plant Varieties and Cultivars
The nerve plant, also known as Fittonia, comes in a wide array of captivating color variations. These nerve plant varieties and cultivars offer gardeners a diverse selection to choose from when adding these tropical beauties to their indoor plant collections.
Popular Cultivars and Their Characteristics
One of the most popular nerve plant cultivars is ‘Pink Angel’, featuring bright pink veins against a backdrop of deep green leaves. Another stunning variety is ‘Purple Vein’, which boasts a striking lavender-striped pattern across the foliage.
For those seeking a more substantial nerve plant, the ‘Leather Leaf’ cultivar is a great choice, producing large, leathery leaves with prominent nerve plant color variations in shades of white and grey.
The ‘Daisy’ nerve plant is a true showstopper, with its large, variegated leaves in a harmonious blend of white, grey, and green tones. This cultivar adds a touch of elegance and visual interest to any indoor space.
Whether you prefer delicate pink veining, striking lavender striations, or bold, variegated foliage, the diverse selection of nerve plant varieties and cultivars ensures there is a perfect option to suit any gardener’s taste and decor.
Pests, Diseases, and Troubleshooting
Nerve plants can be susceptible to common houseplant pests like fungus gnats, mealybugs, aphids, and spider mites. Infestations should be treated immediately—an insecticidal oil, like neem oil, works well—and keep affected plants isolated to prevent the bugs from spreading to other indoor plants.
Diseases and Prevention
Many of the problems associated with Fittonia are the same ones that can affect other tropical houseplants, such as root rot, leaf spot diseases, and powdery mildew. The best way to prevent these diseases is by properly circulating air and maintaining moist foliage that isn’t overly saturated.
Troubleshooting Common Issues
Common issues with nerve plants include yellowing leaves (usually a sign of overwatering), leaf drop (often due to dehydration or cold temperatures), and leaf scorch (indicating too much direct light). Adjusting the plant’s watering, humidity, and light exposure can help resolve these problems.
