Calathea Ornata Pin Stripe

Calathea ornata ‘Pinstripe’ is one of those plants that looks expensive even when it isn’t, which explains why it keeps ending up in living rooms next to questionable furniture decisions. This is a rhizomatous member of the Marantaceae family, grown almost entirely for its dark, glossy leaves painted with fine pink lines that look hand-drawn on purpose. The appeal is visual, not floral, and anyone expecting showy blooms indoors will be waiting a long time with a watering can and a puzzled expression.

What it wants instead is bright indirect light that never actually touches the leaves, soil that stays evenly moist without turning into swamp soup, and humidity high enough that the leaf edges don’t quietly crisp out of spite. It is also non-toxic to pets and humans, which matters because the leaves are eye-level and apparently irresistible to curious cats and toddlers. The lack of calcium oxalate crystals or alkaloid compounds, which are the usual culprits behind mouth irritation in many houseplants, keeps this one firmly in the safe category.

Care is not impossible, but it is precise, and improvisation tends to be punished. Treated correctly, Calathea ornata behaves like a calm, decorative housemate. Treated casually, it becomes a very elegant complaint letter written in brown leaf edges.

Introduction & Identity

The leaves look like pinstripes painted by an overconfident intern with a ruler, which is both the charm and the warning.

Calathea ornata is not subtle, and it is not forgiving, but it is specific. Botanically speaking, the accepted name is Calathea ornata, full stop, without the cultivar gymnastics that haunt some other houseplants.

The ‘Pinstripe’ label is a marketing nickname rather than a separate botanical entity, and the plant behaves exactly like the species regardless of how stylish the tag looks.

It belongs to the Marantaceae family, a group of tropical understory plants known for patterned foliage and dramatic leaf movement, not for tolerance of neglect.

Calathea ornata is a rhizomatous evergreen perennial. Rhizomatous means it grows from thickened horizontal stems under the soil surface, called rhizomes, that slowly creep and produce new shoots. In plain language, the plant expands sideways rather than shooting up a woody trunk.

This growth form explains why it eventually becomes a clump instead of a single upright stem and why dividing it is possible while stem cuttings are a waste of optimism. Evergreen simply means it keeps its leaves year-round in suitable conditions, not that it is immune to shedding them when irritated.

Calathea is often confused with Maranta, and the confusion is understandable because they are close relatives and both get branded as prayer plants. The difference lies in growth habit and leaf posture.

Maranta species tend to sprawl and trail, with thinner stems that flop outward, while Calathea ornata grows more upright, with stiffer petioles that hold the leaves aloft like decorative shields.

Both move their leaves daily, a behavior called nyctinasty.

Nyctinastic movement is not magic and not mood-based.

It is controlled by a joint-like structure at the base of the leaf called a pulvinus, which changes internal water pressure in response to light levels.

When light drops, water shifts within the cells, and the leaf lifts or folds. When light returns, the pressure reverses. This movement costs the plant energy, which is why poor light eventually slows it down.

The pink pinstripes are not a sign of nutrient deficiency, no matter how many internet comments suggest magnesium therapy. They are areas of reduced chlorophyll, genetically programmed into the leaf tissue. Chlorophyll is the green pigment responsible for photosynthesis, and where it is suppressed, other pigments and underlying cell structure become visible.

The pattern is stable under correct light and fades when the plant is starved, not when it needs fertilizer.

At the family level, Marantaceae plants produce phenolic and flavonoid compounds as chemical defenses against herbivory.

These compounds taste unpleasant to insects and microbes but are not toxic to mammals in the way calcium oxalate crystals are. This is why Calathea ornata is considered non-toxic, despite being visually similar to some aroids that absolutely are not.

The confusion comes from leaf shape and gloss, not chemistry.

Authoritative botanical references such as the Royal Botanic Gardens, Kew confirm Calathea ornata’s classification and growth habit, and their species profile is publicly accessible at https://powo.science.kew.org.

Quick Care Snapshot

Care Factor	Calathea ornata Preference
Light	Bright indirect light
Temperature	Warm indoor range
Humidity	Elevated, consistently
Soil pH	Slightly acidic
USDA Zone	10–11
Watering Trigger	Top layer just drying
Water Quality	Low mineral content
Fertilizer	Light, during growth

Bright indirect light means the plant can see the sun but should never feel it. In real rooms, this usually translates to a position a few feet back from an east-facing window or farther from a south-facing one with sheer curtains.

Putting it directly in a sunbeam because the room feels dim will scorch the leaf tissue, and once those pale burn patches appear, they do not heal. Temperature preferences are not exotic, just stable.

Normal household warmth works as long as it does not swing wildly, and cold drafts are particularly damaging because the thin leaf cuticle loses water faster when chilled.

Humidity needs to be higher than the average living room, especially in winter. Elevated humidity slows water loss from the leaves, which reduces edge browning.

This does not mean turning the plant into a bathroom ornament unless there is real light.

Steamy darkness still counts as darkness. Soil pH being slightly acidic simply reflects what happens naturally when organic matter breaks down. Most quality houseplant mixes already fall into this range, and attempting to adjust pH manually usually causes more problems than it solves.

The USDA zone rating of 10 to 11 tells you this plant evolved in frost-free climates.

Indoors, that translates to zero tolerance for cold windowsills in winter.

Watering should be triggered by the top portion of the soil drying slightly, not by a calendar reminder. Sticking to a rigid schedule ignores changes in light, temperature, and humidity, which is how roots end up rotting in February and desiccated in July.

Water quality matters because minerals accumulate in the soil over time. Hard tap water leaves salts behind as water evaporates, and Calathea roots are sensitive to that buildup.

Using filtered or rainwater avoids tip burn caused by mineral stress. Fertilizer should be diluted and used only during active growth. Feeding a stressed plant in low light does not help it recover and often burns the roots instead.

Where to Place It in Your Home

An east-facing window is ideal because it provides gentle morning light that brightens the leaf surface without overheating it.

Morning sun is lower in intensity, which means the mesophyll cells inside the leaf can photosynthesize efficiently without being damaged. South-facing windows are workable, but distance matters.

A few feet back or filtered through a sheer curtain prevents direct rays from striking the leaves.

Ignoring this and placing the plant directly in a bright southern window often results in pale patches and crispy margins within weeks.

West-facing windows are problematic because afternoon sun is both intense and hot.

The leaves heat up faster than they can regulate water loss, which leads to edge scorch that looks like dehydration even when the soil is wet. North-facing windows provide light that is too weak to maintain the pinstripe contrast long-term.

The plant survives, but the pattern fades, petioles elongate, and the overall look becomes floppy and dull.

That is not mystery decline; it is slow starvation.

Bathrooms without windows fail despite the humidity because photosynthesis still requires light.

High moisture in the air cannot replace energy input. Dark corners elsewhere in the home cause similar issues, with petioles stretching toward distant light sources and eventually collapsing under their own weight.

Cold glass is another quiet problem. Leaves pressed against winter windows lose heat rapidly, damaging the thin cuticle and causing translucent patches that later turn brown.

Heater vents are worse.

Hot, dry air blasting directly onto the foliage accelerates water loss so quickly that the leaf margins die before the roots can compensate.

Floor placement versus table height matters because light intensity decreases closer to the ground, especially in rooms with deep window frames. Raising the plant to table height often improves growth simply by improving light exposure.

Airflow should be gentle.

Stagnant air encourages pests, but strong drafts dry the leaves. Rotating the pot occasionally helps maintain symmetrical growth because the plant will always orient its leaves toward the brightest source. Frequent relocation, however, confuses its light-response rhythm and causes stress.

Stability matters more than novelty, and constantly moving it around to “find the perfect spot” usually achieves the opposite.

Potting & Root Health

The rhizomes of Calathea ornata are sensitive to hypoxia, which is a lack of oxygen at the root level. Roots respire just like leaves, and when soil stays saturated, oxygen is displaced by water.

Oversized pots make this problem worse because excess soil holds moisture longer than the roots can use it.

Choosing a pot that only slightly exceeds the root mass helps the substrate dry evenly.

Drainage holes are non-negotiable.

Without them, water accumulates at the bottom, creating anaerobic conditions that invite rot-causing microbes.

Bark in a potting mix improves macroporosity, which means it creates larger air spaces that allow oxygen to move through the soil.

Perlite contributes by keeping the mix from compacting and by facilitating gas exchange. Coco coir retains moisture without collapsing the way peat can, maintaining structure over time.

Dense peat-only mixes compress, exclude air, and suffocate roots, especially when watered frequently.

This is why plants sold in nursery peat often decline after purchase unless repotted.

Plastic pots retain moisture longer because they are non-porous, which can be useful in dry environments but dangerous in humid ones.

Ceramic or terracotta pots allow some moisture to evaporate through the sides, reducing the risk of saturation but increasing watering frequency.

Repotting is typically needed every one to two years, based on rhizome crowding rather than a strict schedule. When the plant dries out unusually fast or pushes against the pot walls, it is time.

Winter repotting delays recovery because growth is slower and root damage takes longer to repair.

Compacted or hydrophobic substrate shows up as water running straight through the pot or pooling on the surface without soaking in. This indicates the organic components have broken down or dried out completely. Research on root oxygenation and container substrates, such as studies summarized by university horticulture departments like North Carolina State University at https://horticulture.ces.ncsu.edu, explains why air-filled pore space is critical for root health.

Ignoring these principles leads to root decline that no amount of leaf misting will fix.

Watering Logic

Calathea ornata requires consistent moisture without saturation, which sounds simple until it is applied in real homes with changing seasons. During active growth in spring and summer, the plant uses more water because light levels and temperatures are higher. In winter, water use slows, not because the plant wants to dry out, but because evaporation and transpiration decrease.

Humidity affects water use as much as temperature.

In dry air, leaves lose water faster, pulling more from the roots even when it is cool.

Soggy rhizomes rot faster than slightly dry ones because anaerobic conditions allow pathogens to proliferate.

Letting the top portion of the soil dry slightly before watering introduces oxygen into the root zone. Finger-depth testing works when translated into behavior.

If the soil feels dry an inch or two down, it is time to water thoroughly.

Pot weight is a reliable diagnostic tool. A freshly watered pot feels heavy, and as it dries, it becomes noticeably lighter. Learning this difference prevents both overwatering and neglect.

A sour or sulfur smell from the soil signals anaerobic activity.

That smell means roots are suffocating, and continued watering will accelerate decline. Leaf edge curl is an early dehydration response, caused by loss of turgor pressure, which is the internal water pressure that keeps cells firm.

Bottom watering can help rehydrate dry mixes evenly, but leaving the pot standing in water too long reverses the benefit and suffocates roots.

What not to do matters. Ice cubes shock tropical roots and create uneven moisture distribution.

Misting alone does not water the plant and can encourage fungal spotting if done excessively. Rigid schedules ignore environmental changes and often result in watering a plant that does not need it.

Adjusting based on observation keeps the root system functional, which is the foundation of everything happening above the soil line.

Physiology Made Simple

The dark green background of Calathea ornata leaves is rich in chlorophyll, which absorbs light energy for photosynthesis. The pale pinstripes exist because those areas contain less chlorophyll by genetic design, not because something is missing.

Bright indirect light maintains this contrast by providing enough energy for the green tissue without damaging the lighter areas.

Too little light reduces overall chlorophyll production, making the pattern fade.

Turgor pressure is what keeps leaves upright.

It works like a water-filled balloon inside each cell. When water is plentiful, cells stay firm. When water is scarce or lost too quickly, cells deflate, and leaves curl or droop.

The pulvinus at the base of each leaf controls movement by shifting this pressure in response to light cues. Thin cuticles, which are the waxy outer layer of leaves, increase humidity dependence because they allow more water to escape.

Harsh sun damages mesophyll cells by overheating them, disrupting photosynthesis and leaving permanent scars.

Common Problems

Why are the leaf edges turning brown?

Brown edges are usually a symptom of water stress combined with low humidity.

Biologically, the leaf margins are where water loss is most pronounced, and when transpiration exceeds uptake, cells die first at the edges. Correcting this involves increasing ambient humidity and improving watering consistency. What not to do is trim aggressively without addressing the cause, because the new growth will repeat the pattern.

Why are the leaves curling inward?

Inward curl indicates loss of turgor pressure, often from dehydration or mineral buildup interfering with water uptake. The plant is conserving surface area to reduce water loss.

Restoring even moisture and switching to low-mineral water corrects the issue. Continuing to fertilize or flush with hard tap water worsens stress by adding salts to already compromised roots.

Why is the pattern fading?

Pattern fade happens under insufficient light. The plant reduces chlorophyll contrast to maximize photosynthetic efficiency. Increasing light exposure without introducing direct sun restores pattern over time.

What not to do is assume fertilizer will fix it, because nutrients cannot compensate for lack of energy.

Why are new leaves small or distorted?

Small or misshapen leaves point to root stress or inconsistent moisture during development.

Leaves form while still rolled, and disruptions at that stage cause permanent deformation. Improving root aeration and stabilizing watering helps future growth.

Avoid misting rolled leaves excessively, which can trap moisture and encourage rot.

Why does it look fine one week and terrible the next?

Rapid decline usually follows an environmental shift such as a temperature drop, missed watering, or sudden light change. Calathea responds quickly because its leaves are thin and metabolically active. The correction is restoring previous conditions and resisting the urge to overcorrect with multiple changes at once, which compounds stress.

Pest & Pathogens

Spider mites are the most common pest and act as humidity indicators. They thrive in dry air and feed by piercing leaf cells, leaving fine speckling. Thrips cause silvery feeding scars and distorted growth.

Early detection requires checking leaf undersides regularly. Spot treatment with diluted alcohol disrupts insect cell membranes, but soaking the plant damages leaf tissue.

Isolation prevents spread, and patience matters because eggs hatch over time.

Root rot results from chronic saturation rather than a single watering mistake.

Infected roots turn brown and mushy, losing function.

Removing affected tissue and correcting soil conditions is necessary.

Leaf removal becomes necessary when tissue is irreversibly damaged and draining resources. Integrated pest management principles from university extension services, such as those outlined by the University of California IPM program at https://ipm.ucanr.edu, emphasize observation and targeted intervention over blanket treatments.

Propagation & Pruning

Propagation with Calathea ornata is refreshingly old-fashioned, which means it relies on physical reality rather than optimism. This plant grows from rhizomes, which are thickened horizontal stems that creep just below the soil surface and send up both roots and leaves.

Think of them as underground train tracks with stations popping up as foliage.

Because each rhizome segment already contains the genetic and structural machinery to produce a new plant, division works reliably when done with restraint and a clean blade. What not to do is attempt stem cuttings in water, because there are no nodes on the leaf stalks capable of producing new growth. All that results is a limp leaf slowly decomposing while pretending something might happen.

Division is best timed to coincide with repotting, ideally when the plant has clearly filled its container and the rhizomes are pressing against the pot walls. The biological reason is simple.

Actively growing rhizomes already have stored carbohydrates and active meristems, which are regions of dividing cells that can repair damage.

Cutting them while growth is active allows wounds to seal faster.

Dividing a stressed or dormant plant, especially in winter when metabolism slows, delays recovery and often triggers leaf loss. What not to do is divide out of impatience, because small divisions with only one leaf struggle to maintain water balance while roots re-establish.

Sterile cuts matter more than people expect.

Rhizomes are fleshy and moist, which makes them an inviting buffet for bacteria and fungi. Using a clean, sharp blade reduces tissue crushing and limits entry points for pathogens.

What not to do is tear the plant apart by hand, because ragged wounds heal slowly and rot enthusiastically.

After division, each section should be potted into a snug container with fresh, well-aerated mix and kept evenly moist, not wet.

Recovery usually takes several weeks, during which growth pauses while roots re-anchor. Panic watering during this phase is a common mistake that leads to rot rather than reassurance.

Pruning is less dramatic but still useful. Removing damaged or aging leaves redirects energy toward healthy growth by reducing maintenance costs for the plant.

Leaves with extensive browning will never recover, because dead tissue cannot regenerate chlorophyll or vascular function. What not to do is trim leaf edges into decorative shapes, which only creates more dead margins and increases water loss.

Cuts should be made at the base of the petiole near the soil line, allowing the plant to seal off the entire structure cleanly.

Pruning does not stimulate bushiness directly, because new leaves emerge from rhizomes, not from cut stems.

It simply prevents the plant from wasting resources on leaves that are already past their usefulness.

Diagnostic Comparison Table

Feature	Calathea ornata	Maranta leuconeura	Philodendron sp.
Family	Marantaceae	Marantaceae	Araceae
Growth form	Rhizomatous clump	Creeping, trailing	Climbing or self-heading
Leaf movement	Strong nyctinasty	Strong nyctinasty	None
Light tolerance	Bright indirect only	Moderate indirect	Broad tolerance
Toxicity	Non-toxic	Non-toxic	Often toxic

Calathea ornata and Maranta leuconeura are frequently lumped together under the casual label of prayer plants, which is botanically sloppy but understandable. Both belong to the Marantaceae family and share nyctinastic leaf movement driven by a pulvinus, a flexible joint at the base of the leaf that adjusts water pressure in response to light cycles. The difference shows up in growth habit.

Calathea ornata grows upright from rhizomes, forming a contained clump, while Maranta tends to sprawl and trail, rooting along the stem.

What not to do is expect Maranta-level forgiveness from Calathea, because ornata has thinner leaves and less tolerance for dry air or erratic watering.

Philodendrons are included in this comparison because they are often mistaken for Calathea by new buyers who see large leaves and assume similar care. Philodendrons belong to the Araceae family, which is defined by calcium oxalate crystals that make many species mildly toxic to pets and people.

Calathea lacks these compounds, which is why it is considered non-toxic.

What not to do is assume similar watering or light tolerance.

Philodendrons handle lower humidity and wider light ranges because their thicker cuticles and different internal anatomy reduce water loss.

Treating Calathea like a Philodendron usually results in crisp edges and sulking leaves rather than lush growth.

For beginners, Maranta is generally more forgiving, Philodendron is the easiest, and Calathea ornata sits in the middle with conditions attached. It rewards consistency rather than experimentation.

If the goal is a plant that tolerates neglect, Calathea is the wrong choice. If the goal is patterned foliage that behaves predictably when its basic needs are met, it earns its place.

If You Just Want This Plant to Survive

Survival with Calathea ornata depends less on advanced technique and more on leaving it alone once the basics are correct. Stable placement matters because the plant adjusts its leaf orientation and internal water balance to a specific light environment.

Constant relocation forces repeated physiological recalibration, which costs energy and often shows up as drooping or yellowing. What not to do is carry it around the house chasing better vibes, because plants respond to photons, not intentions.

Humidity deserves priority because thin-leaved Marantaceae lose water rapidly through transpiration. When surrounding air is dry, the plant closes stomata, which are microscopic pores that regulate gas exchange.

Closed stomata slow growth and reduce turgor pressure, the internal water pressure that keeps leaves firm.

What not to do is rely on occasional misting, which evaporates too quickly to change ambient humidity and can encourage leaf spotting.

A consistent humid environment does more than any spray bottle ever will.

Watering discipline means responding to the plant rather than the calendar.

The soil should remain lightly moist, which in practice means watering when the top layer feels dry but the pot still has some weight. What not to do is water on autopilot, because oversaturation suffocates roots and triggers rot faster than mild dryness ever will.

Light consistency is equally important. Bright indirect light maintains photosynthesis without damaging the mesophyll, the inner leaf tissue where energy production occurs. What not to do is push it into dim corners, because low light reduces carbohydrate production and weakens new growth.

Restraint matters more than intervention.

Fertilizer, pruning, repotting, and relocation are all stressors when applied unnecessarily. Calathea ornata does not respond well to constant adjustment, because each change disrupts hormonal balance and water relations.

Doing less, once conditions are stable, allows the plant’s natural rhythms to take over. Survival is not about perfect care, but about avoiding the mistakes that force the plant into recovery mode again and again.

Buyer Expectations & Long-Term Behavior

Calathea ornata grows at a moderate pace when conditions are stable, which means it neither explodes with new leaves nor sits frozen in time. New leaves emerge rolled tightly like green cigars before unfurling to reveal the pinstripe pattern.

Pattern stability depends almost entirely on light quality.

Bright indirect light preserves contrast, while low light causes the pale striping to fade as chlorophyll production increases uniformly across the leaf.

What not to do is interpret fading as a nutrient deficiency, because adding fertilizer will not recreate genetically programmed pigmentation.

Over six months in a consistent environment, the plant typically fills out rather than stretches, adding leaves from the rhizome and thickening the clump.

Over two years, rhizomes expand laterally, eventually pressing against the pot and signaling the need for repotting.

Long-term survival is entirely possible indoors, provided humidity and water quality remain reasonable.

Calathea ornata is not inherently short-lived.

It simply reacts visibly when conditions drift outside its comfort zone.

Relocation shock is common after purchase or moves between rooms. Leaves may droop or curl as the plant adjusts transpiration rates to new light and humidity. What not to do is overcorrect during this phase.

Given time, the plant usually rebounds as hormone levels stabilize and roots recalibrate water uptake.

Expecting immediate perfection sets up unnecessary panic. This plant rewards patience in the practical sense of not interfering while it sorts itself out.

New Buyer Guide: How to Avoid Bringing Home a Lemon

Choosing a healthy Calathea ornata at the store requires paying attention to structure rather than surface shine.

Leaves should feel firm, which indicates adequate turgor pressure and functional roots.

Limp or floppy leaves often signal chronic dehydration or root damage. What not to do is assume a quick watering will fix structural issues, because compromised roots cannot suddenly supply water just because moisture appears.

Crown density matters because new leaves emerge from the center of the clump. A sparse crown suggests previous stress or aggressive pruning.

Soil moisture at retail is deceptive, since many plants are kept overly wet to reduce watering labor. Lifting the pot provides useful information.

A pot that feels unusually heavy may indicate waterlogged soil, while one that feels feather-light may hide a plant that has been dry too long.

What not to do is trust the surface alone, because topsoil can dry while the lower layers remain saturated.

Pest inspection should focus on the undersides of leaves, where spider mites and thrips feed.

Fine stippling or silvery scars indicate active feeding. Mineral residue on leaf edges or soil surface suggests hard water exposure, which can cause ongoing leaf burn at home.

What not to do is rush the transition after purchase. Allowing the plant to acclimate before repotting or fertilizing reduces shock and improves long-term success.

Blooms & Reality Check

Calathea ornata can produce flowers, but this fact is more botanical trivia than selling point. The flowers of Marantaceae are small, often tucked low in the foliage, and designed for specialized pollinators rather than human admiration.

Indoors, flowering is rare because it requires stable light cycles, high humidity, and mature plants with surplus energy. What not to do is chase blooms with fertilizer, because excessive nutrients encourage soft growth and root damage rather than reproductive structures.

Even when flowers appear, they lack ornamental impact compared to the foliage. The leaves are the feature, engineered to maximize light capture under forest canopies. Accepting this reality prevents disappointment and misguided care changes.

The plant’s value lies in its patterned leaves and movement, not in occasional, underwhelming blooms that most owners will never see.

Is This a Good Plant for You?

Calathea ornata sits at a moderate difficulty level, which means it demands consistency rather than expertise.

It tolerates only modest lapses in humidity and watering, making it better suited to environments where indoor conditions are relatively stable. Homes with forced-air heating or extremely dry climates require extra effort to maintain acceptable humidity. What not to do is assume adaptability, because this plant does not harden itself against poor conditions over time.

The ideal environment includes bright indirect light, predictable temperatures, and air that does not strip moisture from leaves. People who prefer low-maintenance plants or who travel frequently without plant care coverage should consider alternatives.

Those willing to provide steady conditions without constant tinkering will find Calathea ornata cooperative rather than dramatic.

FAQ

Is Calathea ornata easy to care for?

It is manageable with consistency, not forgiving with neglect.

Stable light, humidity, and watering make it straightforward, while erratic care leads to visible decline.

Is it safe for pets? Yes, it is considered non-toxic because it lacks calcium oxalate crystals and alkaloid compounds. Chewing may still damage leaves, but it does not pose a poisoning risk.

Why do the leaves move at night? Leaf movement is driven by nyctinasty, controlled by changes in water pressure within the pulvinus at the leaf base.

This response tracks light cycles rather than sleep in any human sense.

How often should it be watered?

Watering depends on soil moisture and environmental conditions rather than a fixed schedule. The soil should remain lightly moist, never saturated or bone dry.

Can it survive low humidity? Survival is possible but appearance suffers. Low humidity leads to brown edges and slowed growth because transpiration outpaces water uptake.

Does it flower indoors?

Flowering indoors is uncommon and unpredictable. When it happens, the blooms are small and not particularly decorative.

Is it the same as a prayer plant? It belongs to the same family as prayer plants but differs in growth habit and tolerance.

Calathea ornata is generally less forgiving than most Maranta species.

Why do the leaf edges turn brown so easily?

Brown edges result from water stress, mineral buildup, or low humidity damaging delicate leaf margins.

Once tissue is dead, it cannot recover.

Can the pinstripes disappear? Yes, insufficient light causes the contrast to fade as chlorophyll production evens out. Restoring proper light usually improves new growth rather than existing leaves.
