Alocasia Macrorrhiza Giant Taro
Alocasia macrorrhiza, commonly sold as giant taro or an “elephant ear” without much concern for accuracy, is not a polite houseplant. It is a massive tropical aroid with leaves the size of a café table, a thick underground rhizome that behaves like a water pump, and a temperament that assumes you live somewhere bright, warm, and a little bit humid.
When grown indoors, it demands very bright indirect light or gentle morning sun, soil that stays consistently moist without turning into a swamp, and enough airflow around the roots to keep oxygen moving. This is not a plant that forgives guesswork.
It grows large because it moves a lot of water through its tissues, and that hydraulic system fails fast when conditions are wrong.
Giant taro also contains calcium oxalate raphides, which are microscopic needle-shaped crystals, combined with proteolytic enzymes that break down proteins.
Chewing or roughly handling the plant releases these compounds into soft tissue, causing immediate burning, swelling, and a memorable lesson in not using your teeth as gardening tools.
The irritation is severe but localized, not a systemic poison, and panic is unnecessary if exposure happens. Respect is sufficient.
When cared for properly, Alocasia macrorrhiza delivers unapologetic scale and drama indoors, but it will not tolerate dim corners, dry soil, or the belief that “wet-loving” means drowned roots.
Introduction & Identity
The leaves look like a tropical roof panel pretending to be foliage, which is fitting because Alocasia macrorrhiza is built to intercept rainfall, sunlight, and oxygen all at once. Botanically, the accepted name is Alocasia macrorrhiza, and it sits firmly in the family Araceae, the same group that includes philodendrons, monsteras, and peace lilies.
In the plant trade, it is lazily lumped under the name “elephant ear,” a term that also gets applied to Colocasia, Xanthosoma, and anything else with a big leaf and a marketing department. That confusion matters because these genera behave differently indoors, and treating them as interchangeable is a reliable way to kill something expensive.
The Araceae family defends itself chemically, which is why so many of its members cause irritation when damaged.
Alocasia macrorrhiza produces calcium oxalate raphides stored inside specialized cells.
When the tissue is crushed, those crystals fire outward like microscopic darts.
The proteolytic enzymes present in the sap worsen the effect by breaking down proteins in skin and mucous membranes, making the irritation feel sharper and more persistent than a simple rash. This reaction is intense and unpleasant, but it remains localized.
It does not cause systemic poisoning, organ failure, or anything else that would justify internet hysteria.
Gloves are smart, rough handling is not, and chewing the plant is an objectively bad idea.
Growth in Alocasia macrorrhiza is driven by a rhizome, which is a thickened underground stem that creeps horizontally and stores energy. Unlike a root, a rhizome has nodes that can produce both leaves above and roots below.
In simple terms, it is a living battery and plumbing hub combined.
This structure allows the plant to push out enormous leaves when water and oxygen are abundant.
It also means the plant suffocates quickly if the rhizome sits in stagnant, airless soil.
One of the easiest ways to tell Alocasia from its frequent lookalike Colocasia is leaf orientation.
Alocasia leaves tend to point upward or outward with the petiole attaching at the back of the leaf blade, while Colocasia leaves often droop and attach more centrally, giving that classic umbrella look. This difference reflects how water moves through the leaf and how the plant sheds excess moisture.
Leaf size in Alocasia macrorrhiza depends more on water movement than fertilizer. Nutrients matter, but without steady water flow through the petioles, cells cannot maintain turgor pressure, which is the internal water pressure that keeps leaves rigid.
For authoritative taxonomy and distribution information, the Royal Botanic Gardens, Kew maintains an excellent profile that confirms its accepted name and native range, which helps separate fact from plant shop fiction at https://powo.science.kew.org/.
Quick Care Snapshot
| Care Factor | Ideal Range |
|---|---|
| Light | Very bright indirect light or gentle morning sun |
| Temperature | Warm indoor conditions typical of tropical homes |
| Humidity | Moderate to high, above the level that crisps leaf edges |
| Soil pH | Slightly acidic to neutral |
| USDA Zone | 10–11 outdoors only |
| Watering Trigger | Top layer just beginning to dry while lower soil stays moist |
| Fertilizer | Light but regular feeding during active growth |
These values sound abstract until translated into a real room with real windows. Very bright indirect light means the plant should be able to cast a soft shadow for most of the day without being blasted by midday sun. A sheer curtain in an east-facing window works because morning sun is cooler and less intense, giving the leaves enough energy without cooking the chlorophyll.
Placing it several feet back from a south-facing window without diffusion is a mistake because unfiltered midday light can photobleach the leaves, leaving pale, damaged patches that never recover.
Warm temperatures mean the plant expects the kind of indoor conditions people find comfortable in a T-shirt. Cold rooms slow water movement through the rhizome, which causes leaves to droop even when the soil is wet.
That leads many owners to water more, which compounds the problem by suffocating roots. Do not chase drooping leaves with extra water unless the soil has actually dried beyond the surface.
Humidity matters because the leaves are enormous and lose water quickly through transpiration.
This does not mean turning the plant into a fog machine experiment.
Constantly misting the leaves does little for root hydration and can encourage fungal spotting if airflow is poor. What not to do is place it next to a heating vent or air conditioner, because forced air strips moisture from the leaf edges faster than the roots can replace it.
The watering trigger is the most misunderstood part of giant taro care.
The soil should never be bone dry, but it should also never smell sour or swampy.
That smell indicates anaerobic conditions, meaning oxygen has been displaced by water.
Roots need oxygen to function, and without it, they rot.
Fertilizer should be modest and consistent during active growth, not dumped in heavy doses.
Overfertilizing pushes soft growth that collapses under its own weight and burns roots that are already working hard.
Where to Place It in Your Home
Alocasia macrorrhiza does not belong in dim rooms, shadowy corners, or decorative dead zones. Very bright rooms are mandatory because the plant’s leaves are built to process a lot of light, and without it, the entire hydraulic system slows down.
East-facing exposure works best indoors because it provides several hours of gentle morning sun that energizes the plant without overheating leaf tissue. Morning light supports steady photosynthesis, which in turn keeps water moving upward through the petioles.
Unfiltered south-facing sun is a common mistake. The intensity through glass can scorch leaf cells, causing brown patches that look like burn marks.
Once damaged, those areas never heal, and the leaf becomes structurally weaker. West-facing windows are equally problematic because afternoon sun arrives with heat buildup, stressing the plant when it is already transpiring heavily.
North-facing rooms are usually too dim, leading to smaller, weaker leaves and elongated petioles that flop under their own weight.
Bathrooms without windows fail despite the myth that humidity alone is enough.
Light drives growth, not steam from a shower. Corners collapse growth because light arrives from one direction only, forcing the plant to twist its petioles.
Those thick leaf stems are strong but not flexible, and repeated stress leads to cracking. Cold drafts from doors or winter windows shred giant leaves at the margins, while HVAC airflow causes edge burn by accelerating water loss faster than the roots can compensate.
Spacing matters because these leaves are not decorative accents. They need clearance to expand fully without rubbing against walls or furniture, which causes tearing along the veins. Ceiling height is a reality check; this plant grows upward as well as outward, and low ceilings force leaves to bend unnaturally.
Rotation should be minimal.
Constant turning stresses the petioles as they repeatedly reorient toward the light, and stress shows up as drooping and uneven growth.
Potting & Root Health
The rhizome of Alocasia macrorrhiza demands oxygen the way lungs demand air. It thrives in soil that holds moisture while allowing air to circulate freely around roots. Oversized pots are a classic error because excess soil stays wet too long, pushing out oxygen and creating anaerobic conditions.
Anaerobic soil smells sour and feels cold, and it leads directly to rhizome rot. Drainage holes are non-negotiable because gravity is the simplest way to remove excess water and pull fresh air into the potting mix.
A functional substrate relies on macroporosity, which means large air spaces. Bark provides structure and prevents compaction, while perlite creates channels for oxygen diffusion.
Coco coir behaves differently from peat; it holds water evenly but releases it more readily, reducing the risk of suffocation. Heavy garden soil destroys roots by compacting into a dense mass that excludes air, which is why it has no place in a container for this species.
Plastic pots retain moisture longer, which can be useful in very bright, warm rooms where water evaporates quickly. Terracotta breathes and dries faster, which can help prevent rot but demands more attentive watering. Repotting every one to two years is typical when rhizomes begin pressing outward against the pot walls.
Winter repotting stalls recovery because growth slows and roots heal poorly in cool, low-light conditions.
Signs of root suffocation include persistent drooping despite wet soil and a sour smell from the pot.
Thirst looks similar at first but resolves quickly after watering. Confusing the two leads to overwatering and rapid decline.
For deeper reading on container substrate physics and root oxygen needs, university extension resources such as those from North Carolina State University explain how air-filled porosity affects root health at https://horticulture.ces.ncsu.edu/.
Watering Logic
Watering Alocasia macrorrhiza is about maintaining constant moisture without stagnation, which sounds simple until reality interferes. The soil should feel evenly damp below the surface, never dusty dry and never slushy. During active growth, water use is driven more by light intensity than by heat.
Bright light fuels photosynthesis, which pulls water upward through the plant.
In low light, water sits unused in the pot, turning into a liability.
Seasonal reduction in watering is necessary as light levels drop, but drying the plant out completely is not. Allowing the rhizome to desiccate damages fine roots, slowing water uptake when growth resumes.
Soggy rhizomes rot quickly because their thick tissues trap moisture and exclude oxygen. That rot spreads internally before any external symptoms appear, which is why sudden collapse often feels unprovoked.
The finger depth technique works well for large pots.
Checking moisture several inches down gives a realistic sense of what the roots are experiencing. Pot weight is another reliable signal; a freshly watered pot is noticeably heavier, and as water is used or evaporates, the weight drops.
Sour, swampy soil smell indicates anaerobic collapse, which requires immediate action, not more water.
Leaf droop reflects turgor pressure failure, meaning the cells lack internal water pressure to stay rigid.
This can be caused by thirst or by root damage that prevents uptake.
Bottom watering can help massive plants because it encourages roots to grow downward and reduces soil compaction from top watering. What not to do is water on a rigid schedule. The plant responds to conditions, not calendars, and rigid schedules drown more giant taro plants than neglect ever does.
Physiology Made Simple
Turgor pressure is the hydraulic force that keeps Alocasia macrorrhiza upright. Water fills plant cells, pressing outward against cell walls and creating rigidity.
When water flow is uninterrupted, leaves stand tall and broad.
When flow is disrupted, leaves droop because the internal pressure drops.
This is not a sign of laziness; it is physics.
Leaf size depends on uninterrupted water flow because expanding cells require constant hydration. Interruptions lead to smaller leaves because cells stop expanding prematurely. The plant also contains aerenchyma tissue, which are specialized air spaces that help move oxygen through waterlogged environments in the wild.
In a pot, this adaptation only works if the soil allows air movement.
Compacted soil negates this advantage.
Large leaves tear along veins because veins act like stress lines.
Wind, handling, or brushing against objects concentrates force along those lines, causing splits. Intense light photobleaches chlorophyll by overwhelming the pigments that absorb light, leaving pale areas that no longer photosynthesize efficiently.
Stress triggers oxalate crystal release because damaged cells rupture, exposing raphides that would otherwise remain sealed.
Rough handling literally activates the plant’s defense system.
Common Problems
Why are the leaves drooping?
Drooping leaves usually signal a failure in water transport. Either the soil is too dry to supply water, or the roots are damaged and cannot absorb it.
The biology is straightforward: without turgor pressure, the leaf collapses under its own weight.
Correction starts with checking soil moisture below the surface and smelling for sourness.
What not to do is immediately add more water without diagnosing the cause, because watering a suffocating root system accelerates decline.
Why are the leaf edges browning?
Brown edges result from excessive water loss at the margins, where transpiration is highest.
Dry air, HVAC airflow, and inconsistent watering all contribute.
The plant cannot replace water fast enough at the edges, so tissue dries and dies. Increasing ambient humidity and stabilizing watering helps. What not to do is trim edges aggressively, because cutting into living tissue creates new stress points.
Why are leaves tearing so easily?
Tearing happens when large leaves experience mechanical stress from movement or contact.
The veins act as predetermined break points. This is structural, not pathological.
Providing space and minimizing drafts reduces tearing. What not to do is rotate the plant constantly, which twists petioles and increases stress.
Why are new leaves smaller?
Smaller new leaves indicate reduced water flow or insufficient light. The plant scales leaf size to available resources.
Fertilizer is rarely the limiting factor. Improving light and root health restores size.
What not to do is increase fertilizer strength, which burns roots and worsens the problem.
Why is the plant suddenly collapsing?
Sudden collapse often traces back to rhizome rot caused by anaerobic soil. Internal tissues fail before leaves show warning signs. Immediate inspection and removal of rotted tissue may save the plant.
What not to do is assume collapse is natural dormancy without checking roots, because rot spreads quickly.
Pest & Pathogens
Spider mites appear when air is dry and stagnant.
They feed on leaf sap, leaving fine stippling and dull patches.
Their presence indicates environmental imbalance more than bad luck.
Increasing humidity and washing leaves physically disrupts their lifecycle.
Thrips cause silvery scarring and distorted growth, especially on new leaves. Early signs include subtle sheen changes before visible damage appears.
Alcohol applied carefully to affected areas and mechanical removal are effective because these pests rely on delicate exoskeletons. Isolation is necessary because massive foliage touches nearby plants easily, allowing pests to spread unnoticed. Root pathogens such as Pythium thrive in hypoxic soil and cause rapid root decay.
This is not a surface problem; it begins below.
Leaf removal becomes unavoidable when damage is extensive or infected tissue threatens healthy growth. Removing a leaf redirects resources to remaining tissue.
What not to do is ignore early signs or rely on routine spraying without correcting environmental causes. Integrated pest management resources from university extensions, such as those from the University of California, explain how environment and biology intersect at https://ipm.ucanr.edu/.
Propagation & Pruning
Rhizome divisions succeed when cuts are clean and allowed to dry before planting.
Propagation of Alocasia macrorrhiza is refreshingly blunt because the plant itself is blunt about how it grows.
Everything meaningful happens at the rhizome, which is a thick, horizontal stem that creeps along just below the soil surface storing carbohydrates and pushing up leaves when conditions allow. Each swelling or joint along that rhizome contains nodes, which are zones of meristematic tissue capable of producing both roots and shoots. Meristematic tissue simply means cells that are still undecided about their career and can become whatever the plant needs next.
This is why division works so reliably and why trying to propagate this species from leaf cuttings is an impressive waste of time.
Division succeeds because of auxin-driven dominance. Auxins are plant hormones that suppress side growth when a main shoot is active. When a rhizome is cut into sections, that dominance is interrupted, and dormant nodes wake up.
The plant interprets the injury as a need to reestablish territory.
What not to do here is rush the process with a dull knife or tear sections apart by hand.
Ragged wounds stay wet longer, and wet wounds invite rot.
A clean, sharp cut creates a small, defined injury that dries faster and seals itself with corky tissue.
After division, the cut surfaces must be allowed to dry before potting.
This drying period, often called callusing, reduces the chance that fungi or bacteria will colonize exposed tissue.
Planting freshly cut rhizomes directly into damp soil is an open invitation for soft rot organisms that thrive on damaged, waterlogged tissue. The plant does not heal faster because it is planted sooner.
It heals faster because oxygen reaches the wound.
Seed propagation is technically possible but practically irrelevant indoors. Flowers are rare, pollination is unlikely without deliberate intervention, and seedlings are slow and variable.
This species is grown for scale, not genetic novelty.
Anyone promising seed-grown giant taro as a beginner-friendly option is selling optimism rather than plants.
Pruning is equally practical.
Removing old or damaged leaves redirects carbohydrate reserves stored in the rhizome toward new growth. A leaf that is yellowing or collapsing is no longer contributing meaningful photosynthesis, which is the process by which plants convert light into sugars.
Leaving that leaf attached does not save energy; it drains it. What not to do is prune healthy leaves for aesthetics.
Each leaf is a solar panel, and removing functional panels slows overall growth and reduces leaf size over time.
Cuts should be made cleanly at the base of the petiole, which is the leaf stalk, without gouging the rhizome itself.
Diagnostic Comparison Table
Leaf orientation reveals fundamental differences in water and light adaptation.
Understanding Alocasia macrorrhiza becomes easier when it is placed next to plants it is commonly confused with. Visual similarity does not equal biological similarity, and this matters when expectations collide with reality.
| Feature | Alocasia macrorrhiza | Colocasia esculenta | Musa basjoo |
|---|---|---|---|
| Growth form | Upright rhizomatous aroid | Tuberous aroid | Pseudostem-forming monocot |
| Leaf orientation | Held upright, facing outward | Drooping, often pointing downward | Upright to arching |
| Typical indoor use | Statement foliage plant | Rarely suitable indoors | Rarely suitable indoors |
| Toxicity | Calcium oxalate irritation | Calcium oxalate irritation | Mildly irritating sap |
| Moisture tolerance | Moist but oxygenated soil | Tolerates wetter soils | Requires excellent drainage |
| Pet safety | Not pet-safe | Not pet-safe | Generally safer |
Alocasia macrorrhiza and Colocasia esculenta are both aroids, meaning they belong to the Araceae family and share chemical defenses based on calcium oxalate crystals.
These crystals are needle-shaped structures that cause intense irritation when tissue is chewed.
The difference lies in posture and moisture tolerance.
Colocasia evolved for wetter, sometimes flooded environments and holds its leaves in a drooping orientation that sheds water efficiently. Alocasia macrorrhiza prefers constant moisture but still demands oxygen at the roots.
Treating it like Colocasia by keeping it swampy leads to root suffocation and collapse.
Musa basjoo, a cold-hardy banana, is not an aroid at all. It forms a pseudostem, which is a stack of leaf bases rather than a true woody trunk. Bananas tolerate heavy feeding and frequent watering but resent indoor conditions because light levels are rarely sufficient.
Toxicity concerns are also different.
Banana sap can irritate sensitive skin, but it does not carry the same concentrated oxalate defenses. This matters in homes with pets or children, where the chewing risk changes dramatically.
The mistake to avoid is assuming visual scale equals similar care.
Giant leaves do not imply identical biology. Each of these plants fails indoors for different reasons, and Alocasia macrorrhiza fails specifically when oxygen and light are compromised.
If You Just Want This Plant to Survive
Survival care for Alocasia macrorrhiza is about restraint, not constant adjustment. The plant responds best to consistent conditions that allow its internal hydraulic system to stabilize. That system depends on predictable water availability and steady light.
Constant tinkering, especially with watering, disrupts root function and leads to cycles of stress that shrink leaf size over time.
Light consistency matters more than chasing the brightest spot of the week.
Once placed in a very bright room with gentle morning sun, the plant should stay there. Moving it repeatedly in search of perfection forces the petioles to reorient and increases the risk of mechanical stress. These petioles are thick but not flexible in the way woody stems are.
They snap internally long before they visibly fail.
Watering should follow the plant’s pace, not a calendar. Allowing the top layer of soil to slightly dry while the deeper layers remain moist maintains oxygen flow to the rhizome. What not to do is water “just in case.”
Excess water in low light leads to anaerobic conditions, meaning oxygen is displaced by water, and roots cannot respire. Roots need oxygen to convert sugars into energy, and without it, they die quietly and then rot loudly.
Fertilizer moderation keeps the plant alive longer than aggressive feeding. Alocasia macrorrhiza uses nutrients quickly when light and water are abundant, but excess fertilizer salts accumulate in soil and damage root tips.
Root tips are where most nutrient absorption occurs.
Burning them slows growth rather than accelerating it. Feeding lightly during active growth and withholding fertilizer during low-light periods prevents this buildup.
Pot stability is underrated.
A heavy, well-balanced pot prevents tipping, which is not just a furniture concern. Repeated micro-movements damage fine roots and disrupt water uptake.
The plant spends energy repairing instead of growing. Survival is about giving the plant fewer problems to solve, not more attention.
Buyer Expectations & Long-Term Behavior
Alocasia macrorrhiza behaves like a tropical perennial with a strong sense of seasons, even indoors. Under stable, bright conditions, leaf turnover can feel rapid, with new leaves replacing old ones as resources allow. Each leaf represents a significant investment of carbohydrates and water.
When conditions dip, the plant retracts that investment without sentimentality.
Seasonal dormancy indoors is subtle but real. Growth slows in lower light, and the plant may shed a leaf without replacing it immediately. This is not a crisis.
What not to do is respond with increased watering or fertilizer. The plant is conserving energy, not starving. Forcing growth during low light produces weak, undersized leaves that tear easily.
Size expectations indoors should be realistic. Outdoors in tropical climates, leaves can reach truly architectural proportions.
Indoors, ceiling height, light intensity, and humidity impose limits.
Over one year, a healthy plant establishes roots and produces larger leaves than its starting size.
Over three years in stable conditions, it becomes dominant within its space but rarely matches outdoor specimens.
This is not failure; it is physics.
The lifespan of Alocasia macrorrhiza is long when rhizomes remain healthy.
Individual leaves are disposable.
The plant persists through renewal. Relocation shock is common after purchase or moving homes.
Expect a pause in growth and possibly a leaf drop. Recovery takes weeks, not days, because roots must reestablish their water balance before new leaves can inflate properly.
Panic interventions only extend the recovery window.
New Buyer Guide: How to Avoid Bringing Home a Botanical Liability
Structural firmness and balanced moisture signal a plant worth bringing home.
A healthy Alocasia macrorrhiza announces itself through firmness.
The rhizome should feel solid through the pot, not spongy or hollow.
Softness suggests internal rot, which is rarely reversible.
Petioles should stand upright with resistance when gently nudged.
Limp petioles indicate compromised water transport.
Leaf symmetry matters because distorted leaves often reflect past stress that may still be active. While cosmetic damage is acceptable, twisted growth can signal chronic light or root issues. Pot heaviness is another clue.
A pot that feels unusually heavy may be saturated, hiding root rot under the surface.
Waterlogged soil in retail environments is common because it keeps plants looking temporarily lush.
If possible, smell the soil.
A sour or swampy odor indicates anaerobic conditions.
Healthy soil smells neutral or faintly earthy. Pest inspection is non-negotiable with large leaves.
Check undersides for fine webbing or silvery scarring.
Retail flood-watering can mask pests by washing them off temporarily, but eggs remain.
Patience saves money.
Walking away from a compromised specimen prevents months of frustration. What not to do is assume recovery is guaranteed because the plant is large.
Size does not equal resilience. Healthy roots matter more than impressive leaves.
Blooms & Reality Check
Alocasia macrorrhiza produces inflorescences typical of aroids, consisting of a spathe and spadix. The spathe is a modified leaf that wraps around the spadix, which holds the actual flowers.
These structures are biologically interesting but visually underwhelming. Indoors, blooms are rare because the plant prioritizes leaf production when resources are limited.
When blooms do appear, they consume energy that would otherwise support foliage.
This is why many growers remove inflorescences early.
Fertilizer cannot safely force flowering. Excess nutrients push soft growth that collapses or burns.
The plant flowers when it has surplus energy, not when it is pressured.
The mistake is expecting ornamental value from the bloom.
This species is grown for leaves. Any promise of frequent indoor flowering misunderstands its biology and misrepresents its appeal.
Is This a Good Plant for You?
Alocasia macrorrhiza sits at an intermediate difficulty level. It is not fragile, but it is unforgiving of poor light and soggy soil.
Space is a real requirement. Small apartments with low ceilings will feel crowded quickly.
Toxicity risk is manageable but real. Chewing causes intense localized irritation due to calcium oxalate crystals and enzymes. Homes with pets or children who explore with their mouths should avoid this plant entirely.
Ideal homes offer bright rooms, stable temperatures, and owners who prefer observation over constant intervention.
Those who should avoid it include anyone seeking a low-light plant, anyone unwilling to adjust watering habits, and anyone expecting instant gratification. This plant rewards consistency, not enthusiasm.
FAQ
Is Alocasia macrorrhiza easy to care for?
It is easy to maintain once placed correctly, but difficult to rescue when mismanaged. Most problems trace back to light deprivation or root suffocation rather than complexity.
Is giant taro safe for pets?
It is not pet-safe. Chewing causes intense irritation and swelling due to calcium oxalate crystals, making it unsuitable for curious animals.
How big does it get indoors?
Indoors, size is constrained by light and space. Expect large, dominant foliage rather than outdoor-scale proportions.
How often should it be repotted?
Repotting is typically needed every one to two years when rhizomes press against the pot. Repotting too frequently disrupts root stability.
Does it go dormant indoors?
Growth slows significantly in lower light, which mimics dormancy. Leaves may be shed without immediate replacement.
Can it grow outdoors seasonally?
It can be grown outdoors in warm seasons if protected from harsh sun and cold. Sudden exposure changes cause stress.
Why do the leaves droop suddenly?
Sudden droop usually reflects loss of turgor pressure from interrupted water uptake. Root issues or missed watering are common causes.
Is it the same as edible taro?
It is related but not the same as edible taro. Consuming it without proper processing causes severe irritation.
Can it survive low light?
It survives briefly but declines over time. Low light reduces leaf size and weakens overall structure.
