Learn How to Grow Nerve Plants (Fittonia)

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 simple to see the place the widespread title “nerve plant” comes from – these veins actually do appear to be a fragile nervous system mapped throughout the foliage.

These compact houseplants not often develop greater than six to eight inches tall, which makes them superb for small areas, terrariums, or wherever you want a pop of coloration with out taking over a lot room.

Native to the tropical rainforests of South America, you’ll additionally see these bought as mosaic or painted web leaf vegetation.

Nerve vegetation are usually not the simplest 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 focus on the whole lot 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 kind dense mats of foliage beneath the cover thriving in dappled mild and fixed humidity.

With a prostrate, spreading development behavior, stems path alongside the bottom or cascade over the sides of containers, rooting at nodes wherever they contact soil.

This makes nerve vegetation glorious selections for hanging baskets, terrariums, or as tabletop vegetation.

The attribute daring veining creates placing patterns throughout every leaf – relying on the range, these veins seem in white, silver, pink, or pink towards a deep inexperienced background.

Although small white flowers could seem on brief spikes throughout summer season, they’re pretty insignificant in comparison with the showy foliage. Indoor specimens not often flower.

Nerve vegetation are non-toxic to people and pets, so I’m fairly completely happy rising these with a curious Labrador retriever in residence. Not like these dumbcanes that I needed to rehome.

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 particular epithet “albivenis” interprets to “white veins,” although trendy cultivars are available a rainbow of colours.

Leaf edges are sometimes gently crinkled or wavy, including to the textural curiosity.

Nerve vegetation have earned a status as drama queens – they’re infamous for his or her theatrical wilting after they want water.

Methods 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 number of toes 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.

If you happen to’re working with low-light circumstances, nerve vegetation can tolerate it higher than many tropicals, however the vein coloration could fade.

You could have to use 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 finest outcomes.

Nerve vegetation can tolerate transient dips to round 55°F but when it drops under that, you’ll doubtless see leaf drop.

Keep away from inserting them close to chilly drafts, heating vents, or air con items the place temperature fluctuations may cause stress.

An important facet of rising nerve vegetation is that they want not less than 50 p.c relative humidity and so they’re happier nearer to 60 or 70 p.c.

Dry air causes leaf edges to show brown and development slows to a crawl.

There are a number of methods to spice up humidity. A toilet with first rate mild is right – the steam from showers supplies a pure humidity enhance.

You may group houseplants collectively in order that they create their very own microclimate or set the pot on a tray stuffed 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 damp 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 objective is soil that stays evenly moist with out changing into waterlogged.

I like Tank’s Home Plant Potting Combine which incorporates a mix of coco coir, compost, biochar, pumice to assist with drainage, and Tank’s natural fertilizer.

Tank’s Home Plant Potting Combine

You will discover this glorious product out there from Arbico Organics in eight- and 16-quart baggage.

Ensure that no matter container you utilize 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 huge, shallow pots quite 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 development.

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 season, this would possibly imply watering each few days. In fall and winter when development slows, you’ll have to water much less incessantly.

The soil ought to really feel like a well-wrung-out sponge always. You may use 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 vegetation aren’t heavy feeders. Throughout spring and summer season, you’ll be able to apply a balanced liquid houseplant fertilizer diluted to half power each two to 4 weeks.

Overfertilization may cause salt buildup within the soil, resulting in brown leaf suggestions and edges. You may 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 fundamental cultivar teams: Argyroneura, which options white or silver veins, and Verschaffeltii, which shows pink or pink veining.

Traditionally, these had been handled as separate species – F. argyroneura and F. verschaffeltii – however taxonomists now acknowledge them as cultivar teams inside a single species.

Trendy breeding has produced dozens of named cultivars in varied sizes and colours. Listed below are some standouts:

Most are bought merely labeled by vein coloration – white, pink, or pink – with out particular cultivar names.

Pink Nerve Plant

You will discover a pink selection in two-and-a-half-inch pots out there from Hirt’s Gardens by way of Walmart.

Pink-Veined Nerve Plant

If pink is extra your model, Hirt’s Gardens has specimens in three-inch pots out there by way of Walmart.

White Nerve Plant

Choose white? Decide up vegetation in four-inch pots from Florida Home Vegetation by way of Walmart.

A number of named cultivars sometimes present up at specialty nurseries. Listed below are a number 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 development 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 sort of silvery white quite than inexperienced.

Upkeep

Pinch again stem suggestions usually to encourage bushy development. Left to their very own gadgets, particularly in low mild circumstances, nerve vegetation can change into leggy.

Pinching simply above a leaf node redirects power into lateral development, 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 widespread when grown indoors, most growers pinch them off as flowering takes power away from foliage manufacturing.

You’ll doubtless have to repot yearly or two. If you happen to see roots rising out of the drainage holes, it’s time to pot up.

The perfect 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 sure, and place it within the new pot on the identical depth it was within the earlier container.

Propagation

One of many joys of rising Fittonia is how simply it propagates. You may create new vegetation by way of stem cuttings or division, each of which have excessive success charges.

Stem Cuttings

In spring or early summer season, choose a wholesome stem with not 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 slightly below a node.

Take away the decrease leaves from the underside inch of the stem, leaving two to 3 leaves on the prime.

At this level you may have two choices: you’ll be able to 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 are usually not submerged.

Change the water each few days to maintain it contemporary.

Roots ought to seem inside two to 3 weeks. When roots attain about an inch lengthy – normally after 4 to 6 weeks – pot up the chopping in soil.

If you happen to want to propagate in soil, fill a small pot with moist, well-draining potting combine and insert the chopping an inch deep.

By Division

You probably have a mature Fittonia that has outgrown its container you’ll be able to divide it to provide new vegetation.

Gently take away the nerve plant from its pot and shake off extra soil so you’ll be able to see the roots clearly.

Utilizing your fingers or a clear knife, separate the foundation 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 contemporary potting combine and water effectively. Keep even moisture, however don’t permit the soil to change into waterlogged.

New development ought to seem inside a number of weeks.

Pests and Illness

Fittonia species don’t are likely to endure from pests or illnesses except they’re careworn by low humidity, overwatering, or lack of sunshine.

Pests

The commonest 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.
