Fittonia spp.
There’s one thing nearly hypnotic about Fittonia leaves. The veining sprawls throughout every leaf in intricate patterns of white, pink, or pink towards deep or brilliant inexperienced.
It’s straightforward to see the place the frequent identify “nerve plant” comes from – these veins actually do appear to be a fragile nervous system mapped throughout the foliage.

These compact houseplants hardly ever develop greater than six to eight inches tall, which makes them preferrred for small areas, terrariums, or wherever you want a pop of shade with out taking on a lot room.
Native to the tropical rainforests of South America, you’ll additionally see these offered as mosaic or painted internet leaf crops.
Nerve crops will not be the best houseplants to domesticate and so they have a status for being a bit fussy. That’s okay, I’m a bit fussy too.
On this information, I’ll talk about every part that you must know to maintain yours thriving. Right here’s what I’ll cowl:
Fittonia species are creeping evergreen perennials native to the tropical rainforests of Peru, Colombia, Ecuador, Bolivia, and northern Brazil.
On the forest flooring, they type dense mats of foliage beneath the cover thriving in dappled mild and fixed humidity.
With a prostrate, spreading progress behavior, stems path alongside the bottom or cascade over the sides of containers, rooting at nodes wherever they contact soil.
This makes nerve crops glorious decisions for hanging baskets, terrariums, or as tabletop crops.
In USDA Hardiness Zones 10 to 12, they are often grown outdoor as floor cowl in shady, protected areas.
The ovate leaves measure two to 4 inches lengthy with a delicate texture and barely quilted look.
The attribute daring veining creates hanging patterns throughout every leaf – relying on the variability, these veins seem in white, silver, pink, or pink towards a deep inexperienced background.
Although small white flowers might seem on quick spikes throughout summer time, they’re pretty insignificant in comparison with the showy foliage. Indoor specimens hardly ever flower.
Nerve crops are non-toxic to people and pets, so I’m fairly completely satisfied rising these with a curious Labrador retriever in residence. Not like these dumbcanes that I needed to rehome.

Genus: Fittonia
Species: Albivenis, gigantea
The genus was named after Elizabeth and Sarah Fitton, Irish sisters whose e-book “Conversations on Botany,” revealed in 1817, helped popularize botanical research amongst girls.
There are two species within the Fittonia genus, F. albivenis and F. gigantea.
F. albivenis is the first species grown as a houseplant. The precise epithet “albivenis” interprets to “white veins,” although fashionable cultivars are available in a rainbow of colours.
Leaf edges are sometimes gently crinkled or wavy, including to the textural curiosity.
Nerve crops have earned a status as drama queens – they’re infamous for his or her theatrical wilting after they want water.
The excellent news is that they bounce again shortly when supplied with the mandatory moisture, often inside an hour or two.
This predictable habits really makes them simpler to look after than many houseplants, since they let you know precisely after they want consideration.
Tips on how to Develop
These tropical natives need circumstances that mimic their rainforest residence: heat, humidity, and constant moisture.
Gentle
Fittonia species thrive in brilliant, oblique mild. Consider the dappled daylight filtering by a rainforest cover.
An east-facing window works effectively or a spot a couple of ft again from a south- or west-facing window the place they received’t be uncovered to harsh rays.
An excessive amount of direct solar will scorch the leaves inflicting them to show brown and crispy.
Too little mild and the plant turns into leggy with stems stretching towards the sunshine supply.
Should you’re working with low-light circumstances, nerve crops can tolerate it higher than many tropicals, however the vein coloration might fade.
You could want to make use of a develop mild if pure mild is proscribed.
Temperature and Humidity
This tropical species wants heat temperatures – however not too scorching! Hold the temperature between 60 and 80°F for greatest outcomes.
Nerve crops can tolerate temporary dips to round 55°F but when it drops under that, you’ll seemingly see leaf drop.
Keep away from putting them close to chilly drafts, heating vents, or air-con models the place temperature fluctuations may cause stress.
Crucial side of rising nerve crops is that they want no less than 50 % relative humidity and so they’re happier nearer to 60 or 70 %.
Dry air causes leaf edges to show brown and progress slows to a crawl.
There are a number of methods to spice up humidity. A rest room with respectable mild is right – the steam from showers supplies a pure humidity increase.
You possibly can group houseplants collectively so that they create their very own microclimate or set the pot on a tray crammed with pebbles and water, ensuring the pot sits on the pebbles above the water line.
You can too develop Fittonia in a terrarium which supplies a moist atmosphere.
Soil
Select a potting medium that’s moisture-retentive however well-draining.
A peat-based or coco coir combine with added perlite or vermiculite is right. The purpose is soil that stays evenly moist with out turning into waterlogged.
I like Tank’s Home Plant Potting Combine which accommodates a combination of coco coir, compost, biochar, pumice to assist with drainage, and Tank’s natural fertilizer.
Tank’s Home Plant Potting Combine
Yow will discover this glorious product obtainable from Arbico Organics in eight- and 16-quart luggage.
Be sure that no matter container you employ has drainage holes. That is non-negotiable as oversaturated soil can result in root rot.
As a result of these are shallow-rooted, they do effectively in extensive, shallow pots relatively than deep containers.
Water
These houseplants are infamous for his or her dramatic fainting act when they’re thirsty – leaves wilt spectacularly, flopping over like they’ve given up on life.
The excellent news? Give them a drink and so they’ll sometimes perk up inside an hour or two.
Nonetheless, repeated wilting episodes will finally harm the plant, inflicting leaf drop and stunted progress.
Hold the soil constantly moist however not soggy. Water when the highest quarter-inch of soil feels dry to the contact.
Throughout the rising season in spring and summer time, this may imply watering each few days. In fall and winter when progress slows, you’ll must water much less often.
The soil ought to really feel like a well-wrung-out sponge always. You should utilize a moisture meter to information you.
Use room-temperature water to keep away from stunning the roots. See our information to watering houseplants right here.
Fertilizer
Nerve crops aren’t heavy feeders. Throughout spring and summer time, you may apply a balanced liquid houseplant fertilizer diluted to half energy each two to 4 weeks.
In fall and winter, cut back to as soon as a month or skip fertilizing totally since progress naturally slows.
Should you potted in a medium that already has compost or fertilizer, you may skip feeding altogether and simply refresh the soil annually.
Overfertilization may cause salt buildup within the soil, resulting in brown leaf suggestions and edges. You possibly can study extra about fertilizing houseplants right here.
Species and Cultivars
As talked about, the Fittonia genus consists of two species however F. albivenis is by far the commonest in cultivation.
F. albivenis is split into two most important cultivar teams: Argyroneura, which options white or silver veins, and Verschaffeltii, which shows pink or pink veining.
Traditionally, these have been handled as separate species – F. argyroneura and F. verschaffeltii – however taxonomists now acknowledge them as cultivar teams inside a single species.
Fashionable breeding has produced dozens of named cultivars in varied sizes and colours. Listed here are some standouts:
Most are offered merely labeled by vein shade – white, pink, or pink – with out particular cultivar names.
Pink Nerve Plant
Yow will discover a pink selection in two-and-a-half-inch pots obtainable from Hirt’s Gardens through Walmart.
Pink-Veined Nerve Plant
If pink is extra your fashion, Hirt’s Gardens has specimens in three-inch pots obtainable through Walmart.
White Nerve Plant
Want white? Decide up crops in four-inch pots from Florida Home Vegetation through Walmart.
Just a few named cultivars sometimes present up at specialty nurseries. Listed here are a couple of standout choices:
Pink Angel
‘Pink Angel’ is a miniature Verschaffeltii Group cultivar that sometimes reaches simply three to 4 inches tall with a dense, bushy progress behavior.
The leaves are small with intense brilliant pink veining that covers a lot of the floor. Works effectively in terrariums and small containers.
Ruby Pink
A Verschaffeltii Group choice, ‘Ruby Pink’ options darkish inexperienced leaves with wealthy crimson veining.
The pink coloration is deep and saturated, creating daring distinction towards the olive-green background.
White Anne
‘White Anne’ is an Argyroneura Group cultivar with dense white veining that dominates the leaf floor, leaving solely skinny strips of darkish inexperienced between the veins.
The general impact is nearly silvery white relatively than inexperienced.
Upkeep
Pinch again stem suggestions often to encourage bushy progress. Left to their very own gadgets, particularly in low mild circumstances, nerve crops can grow to be leggy.
Pinching simply above a leaf node redirects power into lateral progress, making a fuller, extra dense plant.
You can too take away any yellowed, brown, or broken leaves as they seem. Simply snip them off on the base.
If flower spikes seem, which isn’t frequent when grown indoors, most growers pinch them off as flowering takes power away from foliage manufacturing.
You’ll seemingly must repot yearly or two. Should you see roots rising out of the drainage holes, it’s time to pot up.
The most effective time to do that is in spring, when the plant is actively rising.
Select a brand new pot only one to 2 inches bigger in diameter than the present container. Going too massive can result in overly moist soil since there received’t be sufficient root mass to take up the moisture.
Gently take away the plant, loosen the roots barely in the event that they’re tightly certain, and place it within the new pot on the identical depth it was within the earlier container.
Fill in across the roots with recent potting combine and water effectively.
If your house may be very dusty, wipe leaves gently with a moist material sometimes, or give the entire plant a delicate rinse in lukewarm water if it’s sufficiently small to maneuver simply to a sink or bathe.
Propagation
One of many joys of rising Fittonia is how simply it propagates. You possibly can create new crops through stem cuttings or division, each of which have excessive success charges.
Stem Cuttings
In spring or early summer time, choose a wholesome stem with no less than two to 3 leaf nodes.
Use clear, sharp scissors or pruning shears to take a chopping two to 4 inches lengthy, making your reduce just under a node.
Take away the decrease leaves from the underside inch of the stem, leaving two to 3 leaves on the high.
At this level you’ve two choices: you may root in water or soil.
Set the chopping in a small jar or glass with sufficient water to cowl the nodes however make sure the leaves will not be submerged.
Change the water each few days to maintain it recent.
Roots ought to seem inside two to 3 weeks. When roots attain about an inch lengthy – often after 4 to 6 weeks – pot up the chopping in soil.
Should you want to propagate in soil, fill a small pot with moist, well-draining potting combine and insert the chopping an inch deep.
Cowl the pot with a transparent plastic bag or place it in a propagation tray with a humidity dome to keep up moisture. Set it in brilliant, oblique mild.
Hold the soil constantly moist however not waterlogged. You’ll know the chopping has rooted while you see new progress rising, sometimes inside three to 4 weeks.
By Division
When you’ve got a mature Fittonia that has outgrown its container you may divide it to supply new crops.
Gently take away the nerve plant from its pot and shake off extra soil so you may see the roots clearly.
Utilizing your fingers or a clear knife, separate the basis ball into two or three sections, ensuring every division has each roots and stems with foliage hooked up.
Pot every part in its personal container with recent potting combine and water effectively. Keep even moisture, however don’t permit the soil to grow to be waterlogged.
New progress ought to seem inside a couple of weeks.
Pests and Illness
Fittonia species don’t are inclined to undergo from pests or illnesses except they’re harassed by low humidity, overwatering, or lack of sunshine.
Pests
The most typical pests that present up are sapsuckers: mealybugs, scale, and spider mites. Fungus gnats can seem in oversaturated circumstances.
Fungus Gnats
Fungus gnats are small flies and whereas the adults don’t do a lot harm, the larvae feed on natural matter and roots.
Yellow sticky traps catch the adults. You can too drench the soil with diluted neem oil to kill larvae.
Learn our information to managing fungus gnats right here.
Mealybugs
Mealybugs seem as white, cottony clusters on stems and leaf axils. They suck sap, inflicting yellowing and stunted progress.
For mild infestations, dab particular person bugs with a cotton bud dipped in rubbing alcohol.
Within the case of a heavy infestation, spray the plant totally with insecticidal cleaning soap or neem oil, ensuring to coat either side of leaves and all stems.
Be taught extra about mealybugs right here.
Scale
Scale bugs appear to be small brown or tan bumps on stems and leaves. They’re motionless however damaging – sucking sap and weakening the plant over time.
Take away them manually with a cotton bud dipped in rubbing alcohol, then deal with the plant with neem oil or horticultural oil to catch any you missed.
Take a look at our information to managing scale to study extra.
Spider Mites
Spider mites are tiny arachnids that create positive webbing between leaves. Leaves might develop stippling and finally flip brown.
They thrive in dry circumstances, which is one purpose sustaining humidity is so necessary.
You’re unlikely to see the pests themselves as they’re so small however in case you discover webbing, spray the plant with water to knock them off. You can too use neem oil or insecticidal cleaning soap.
Illness
Most illness points stem from an excessive amount of moisture – both within the soil or on the foliage.
Leaf Spot
Leaf spot can develop when water sits on the foliage for prolonged durations.
Varied fungi and micro organism trigger comparable signs: brown, tan, or black spots on leaves, typically with yellow halos.
Water on the soil degree relatively than from above. Enhance air circulation. Take away affected leaves promptly. If the issue persists, deal with with neem oil or a copper-based fungicide.
Powdery Mildew
Powdery mildew sometimes exhibits up as white, powdery patches on the foliage often in circumstances with excessive humidity however poor air circulation.
Enhance air motion, cut back humidity barely if potential, and deal with with neem oil.
Be taught extra about managing powdery mildew right here.
Root Rot
Root rot, attributable to varied fungi and water molds together with Pythium species, is probably the most critical concern.
It seems as yellowing decrease leaves, wilting regardless of moist soil, and finally mushy, blackened roots.
If root rot develops, take away the plant from its pot, trim away affected roots with clear scissors, repot in recent soil, and regulate your watering schedule.
Our information to managing root rot has extra info.
Don’t Lose Your Nerve
Regardless of their fussy status, Fittonia species aren’t really that tough to develop while you perceive what they want.
Get the humidity proper, hold the soil constantly moist however not waterlogged, and supply brilliant oblique mild. You’ll be rewarded with vibrant, patterned foliage that brings tropical aptitude to small areas.
