Curio Rowleyanus String Of Pearls

Curio rowleyanus, better known as String of Pearls, is the plant that convinces people they are “succulent people” right up until it proves otherwise. It grows as a trailing cascade of round, bead-like leaves that look decorative enough to be fake, except they are very much alive and very much opinionated. Each little sphere is a modified leaf designed to store water, which is why this plant behaves less like a leafy houseplant and more like a drought-trained minimalist.

It wants bright indirect light with a bit of gentle direct sun, the kind that arrives in the morning and leaves before things get aggressive. It wants soil that dries completely between waterings, not mostly dry, not kind of dry, but dry enough that you briefly wonder if you’ve forgotten it.

It also contains pyrrolizidine alkaloids, which are naturally occurring compounds that can damage the liver if eaten repeatedly.

That toxicity matters for pets and small humans with poor judgment, but it does not leap out of the plant and attack people who touch it.

This is a hanging succulent vine that rewards restraint, punishes fussing, and looks spectacular when left alone in the right light. It is not fragile, but it is very good at dying quietly if ignored incorrectly.

INTRODUCTION & IDENTITY

String of Pearls is a plant that looks like jewelry but behaves like a cactus with opinions. The round leaves hang in long strands, daring people to water them the same way they water pothos, and then acting shocked when that ends badly.

Botanically speaking, the accepted name is Curio rowleyanus, though it spent many years under the name Senecio rowleyanus. The reclassification happened when botanists realized that the old Senecio group was a taxonomic junk drawer, and Curio was created to separate out certain succulent species with distinct growth and anatomical traits.

The plant sits in the Asteraceae family, which is the same family that contains daisies and sunflowers, even though it looks nothing like them unless it decides to flower, which indoors is rare enough to feel like a rumor.

Despite its trailing habit, Curio rowleyanus is not a vine in the woody, twining sense.

It does not climb, it does not lignify into wood, and it does not thicken into structural stems. It simply drapes, using gravity as its growth strategy. What makes it a succulent is not the trailing form but the leaf modification.

Each pearl is a swollen leaf packed with water-storing tissue, technically called parenchyma, which allows the plant to survive long dry spells in its native environment of arid southern Africa. The spherical shape is not a decorative accident.

A sphere has the lowest surface area relative to volume, which means less exposed tissue and less water lost to evaporation.

This is a plant that has done the math.

One of the most interesting features is the thin, translucent stripe running along each pearl.

This is called an epidermal window.

Instead of exposing a large flat leaf surface to intense sunlight, the plant allows light to enter through this window and penetrate into the interior photosynthetic tissue. This reduces heat load and water loss while still letting the plant make sugars.

It is an elegant solution, and also the reason these pearls scorch when placed in harsh afternoon sun. The window works like a skylight, not a blast shield.

Curio rowleyanus uses CAM photosynthesis, which stands for Crassulacean Acid Metabolism. In plain language, this means it opens its stomata, the microscopic pores used for gas exchange, at night instead of during the day.

Night air is cooler and more humid, so less water escapes. Carbon dioxide is stored overnight and used during the day to make sugars while the pores stay mostly closed.

This is why the plant is slow-growing and water-efficient, and also why frequent watering is such a bad idea.

The entire metabolism is built around scarcity.

The plant contains pyrrolizidine alkaloids, a class of compounds used as a chemical defense against herbivores.

These compounds are hepatotoxic, meaning they damage the liver over time if ingested repeatedly.

The key word is ingested.

Touching the plant, brushing past it, or getting sap on intact skin does not pose a realistic risk.

The concern is pets or people chewing on it like a salad, which should be discouraged for obvious reasons.

Toxicity is cumulative, not immediate, which is why a single nibble is unlikely to cause drama, but habitual snacking absolutely can.

Botanical authorities such as the Royal Botanic Gardens, Kew, document this chemistry clearly and without hysteria, which is refreshing in a world that likes to panic about plants.

More detail on the plant’s classification and morphology can be found through Kew’s Plants of the World Online database, which treats Curio rowleyanus with the seriousness it deserves.

QUICK CARE SNAPSHOT

The basic care parameters for Curio rowleyanus look simple on paper, which is exactly why people mess them up. Numbers without context invite interpretation, and interpretation is how roots rot. The table below gives the raw facts before they are translated into real-world behavior.

Care Factor	Recommended Range
Light	Bright indirect with some gentle direct sun
Temperature	65–80°F
Humidity	Low to average household
Soil pH	Slightly acidic to neutral
USDA Zone	9–11
Watering Trigger	Soil completely dry
Fertilizer	Dilute, infrequent during growth

Bright indirect light means placing the plant near a window where it can see the sky but is not being cooked by it.

A few hours of morning sun are beneficial because the light is strong without being punishing.

Afternoon sun through glass is hotter than it looks, and that heat concentrates on the pearls, damaging the epidermal windows and causing permanent scars. Putting it in low light because “succulents like shade” is a misunderstanding.

In low light, the plant stretches its internodes, which are the spaces between pearls, in an attempt to find more light. The result is thin, weak strands that break easily and never look full again.

Hanging the plant is fine, but hanging it far from a window because it looks nice in a corner is how you end up with a sad green necklace with commitment issues.

Temperature recommendations translate to standard indoor comfort. If the room feels fine to sit in without a sweater or a fan, the plant is comfortable.

What not to do is place it near exterior doors in winter or directly above heating vents.

Cold drafts cause cells to lose turgor pressure, which is the internal water pressure that keeps the pearls round. Heat blasts dry the soil unevenly and stress the roots.

The plant will not scream in protest.

It will just quietly drop pearls.

Humidity is refreshingly irrelevant here.

This is not a plant that wants misting, pebble trays, or bathroom spa days. High humidity slows evaporation from the soil surface, which keeps roots wet longer than they want to be. Bathrooms without strong windows fail because they combine low light with persistent moisture, which is the exact opposite of what this plant evolved to tolerate.

Kitchens can work if there is bright light, but placing the plant above a sink and splashing it regularly is a mistake that smells like rot.

Soil pH in the slightly acidic to neutral range is common for most houseplants, which means the focus should be on texture rather than chemistry.

A mineral-heavy mix that drains fast is non-negotiable.

What not to do is use regular potting soil straight from the bag.

Those mixes are designed to hold moisture for thirsty plants and will suffocate succulent roots.

USDA zones only matter outdoors, and only if you live somewhere warm enough that frost is a rumor.

Anywhere colder means this plant is an indoor resident year-round.

Watering should be triggered by dryness, not by schedule. If the soil is even slightly cool or damp below the surface, watering is premature.

Overwatering kills far faster than underwatering because roots deprived of oxygen die, and dead roots invite pathogens.

Fertilizer should be diluted to half or quarter strength and used sparingly during active growth. Dumping fertilizer into dry soil or feeding in winter when growth slows does not encourage vigor. It stresses the roots and builds up salts, which damage delicate tissues.

WHERE TO PLACE IT IN YOUR HOME

Placement determines whether String of Pearls thrives or slowly unravels. Bright indirect light with some morning sun works because it mirrors the plant’s natural conditions, where sunlight is intense but filtered and arrives at an angle. Morning sun is cooler and less concentrated, which allows the epidermal windows to admit light without overheating the tissue beneath.

Harsh afternoon sun, especially through glass, acts like a magnifying lens.

Pearls exposed to that intensity develop bleached patches or reddish scars that never heal. Turning the plant after damage occurs does not reverse it.

Those pearls are permanently cosmetic casualties.

Low light is equally destructive but in a slower, sneakier way.

When light levels drop, the plant responds by elongating its stems to search for better conditions.

The pearls space out, the strands weaken, and the overall look shifts from lush cascade to stringy disappointment. Ceiling hooks far from windows are a common failure point.

Hanging a plant high feels logical, but light intensity drops dramatically with distance.

A hook three feet from a window is very different from one ten feet away, even if the room feels bright.

Bathrooms without strong windows are a frequent graveyard.

The combination of low light and high ambient moisture keeps the soil damp and the metabolism sluggish.

Kitchens can work if there is a bright window and good air movement, but placing the plant near a stove introduces heat fluctuations and grease residues that coat leaf surfaces and interfere with gas exchange.

Cold drafts from winter windows or air conditioning vents cause pearls to shrivel because cold reduces water movement within the plant. The tissue contracts, and repeated stress leads to drop.

Rotating hanging pots is not optional if you want even growth. Plants grow toward light, and Curio rowleyanus is no exception.

Without rotation, one side thickens while the other thins out. What not to do is spin the plant daily out of guilt.

Rotation every couple of weeks is sufficient. Constant movement prevents the plant from establishing stable growth patterns and increases mechanical stress on the stems.

POTTING & ROOT HEALTH

Roots are the entire story with this plant, even though they are the part no one sees. Shallow pots outperform deep ones because Curio rowleyanus has a relatively shallow root system that spreads horizontally rather than diving down.

Deep pots hold excess moisture below the root zone, creating a wet layer that never dries and slowly suffocates roots. Drainage holes are mandatory because stagnant water displaces oxygen, and roots need oxygen to respire.

Without it, cells switch to inefficient anaerobic metabolism and die, which opens the door to rot organisms.

Mineral-heavy mixes prevent hypoxia by maintaining air pockets even when watered.

Components like perlite, pumice, or horticultural grit create physical space for oxygen to move through the soil. This is gas exchange, not just drainage. Peat-heavy soils collapse when wet, eliminating those air spaces and trapping water around roots.

What not to do is assume that adding sand to regular potting soil fixes the problem. Fine sand actually fills gaps and worsens compaction.

Plastic pots retain moisture longer, which can be useful in very bright, warm conditions where drying is rapid.

Terracotta breathes, allowing moisture to evaporate through the pot walls, which speeds drying and reduces rot risk in average homes.

Choosing the wrong material for your environment creates a mismatch that watering habits rarely fix.

Repotting should only occur when roots have filled the pot, not when the plant looks a little tired. Excess soil volume stays wet too long and invites trouble.

Winter repotting increases rot risk because growth slows and roots are less able to recover from disturbance.

Signs of anaerobic soil conditions include a sour smell, blackened roots, and pearls yellowing from the base upward. Once this starts, correcting care may not be enough. Research on succulent root oxygenation, including work summarized by university extension programs and soil science resources such as those from the University of Arizona Cooperative Extension, underscores how critical air-filled porosity is for succulent health.

WATERING LOGIC

Watering is where most relationships with String of Pearls end. The plant requires a full dry-down between waterings, which means the soil must be dry all the way through, not just on the surface. Seasonal differences matter because light intensity drives water use more than temperature.

Bright summer light increases photosynthesis and water consumption, while winter’s low light slows everything down even if the room is warm.

Watering on a fixed schedule ignores this reality and leads to rot.

Overwatering kills faster than underwatering because roots deprived of oxygen die quickly, while a thirsty plant can rehydrate if tissues are still alive. Pearl firmness is the best indicator of hydration. Firm, smooth pearls indicate adequate internal pressure.

Soft, wrinkled pearls suggest water deficit, but watering immediately without checking soil moisture can cause bursting.

Burst pearls occur when a plant has been drought-stressed and then suddenly flooded.

Cells swell faster than the epidermis can stretch, and the pearl splits. It looks dramatic and is entirely preventable.

The pot weight method is reliable because dry soil weighs less than wet soil. Lifting the pot before and after watering teaches your hands what dry actually feels like. Bottom watering works well for hanging plants because it allows moisture to wick upward evenly without splashing pearls or compacting soil.

What not to do is mist the plant.

Misting increases surface moisture without hydrating roots and creates conditions for fungal problems. Another mistake is watering a plant that is already stressed by low light.

Without adequate light, the plant cannot use the water, and it sits in the soil like a bad decision.

PHYSIOLOGY MADE SIMPLE

CAM photosynthesis means Curio rowleyanus opens its stomata at night to collect carbon dioxide, storing it as organic acids.

During the day, those acids are broken down to fuel sugar production while the stomata stay mostly closed.

This nighttime gas exchange conserves water but limits growth speed.

Turgor pressure is the internal water pressure that keeps cells rigid.

In this plant, turgor is visible as pearl firmness.

When water is scarce, turgor drops and pearls wrinkle.

Epidermal windows act like skylights, directing light into the interior tissues. Pearls collapse before stems die because the plant prioritizes stem survival.

Succulent tissue hides stress until it becomes severe, which is why problems often seem sudden.

COMMON PROBLEMS

Why are the pearls shriveling?

Shriveling pearls usually indicate water deficit, but that does not automatically mean the plant needs water. If roots are damaged from past overwatering, they cannot absorb moisture even when it is present.

The biology is simple. No functional roots means no water uptake, which leads to dehydration symptoms.

Watering again only worsens the problem.

Correcting this requires assessing root health, improving light, and allowing damaged tissue to recover or be removed.

What not to do is panic-water, because that accelerates decline.

Why are the pearls turning yellow?

Yellowing often points to excess moisture and reduced chlorophyll production.

Chlorophyll is the green pigment responsible for photosynthesis.

When roots are stressed, nutrient uptake falters and chlorophyll breaks down. Yellow pearls near the base suggest chronic wet soil.

Removing yellow pearls does not fix the cause.

Drying the soil, improving drainage, and increasing light are the real corrections. Fertilizing a yellowing plant is a mistake because stressed roots cannot process nutrients.

Why are strands breaking or dying back?

Mechanical stress, low light, and uneven watering weaken stems. As internodes elongate, stems thin and snap under their own weight.

Dying back can also occur when the base of the plant rots.

Cutting healthy sections and rerooting is sometimes the only solution. What not to do is keep tugging on strands to check firmness. That just adds injury.

Why is growth sparse and elongated?

Sparse growth is a direct response to insufficient light.

The plant reallocates resources to reach brighter conditions, sacrificing density. Increasing light gradually corrects this, but old elongated growth will not fill in.

Pruning and rerooting are required. Moving the plant suddenly into intense sun causes burn, so adjustment must be gradual.

Why are pearls bursting?

Bursting pearls result from rapid rehydration after drought. Cell walls rupture when internal pressure rises too quickly. Preventing this means consistent care, not extreme cycles.

What not to do is ignore the plant for weeks and then soak it like an apology.

PEST & PATHOGENS

Mealybugs are the primary pest of Curio rowleyanus. These insects insert their mouthparts into plant tissue and extract sap, which collapses turgor pressure and causes localized shriveling.

Early signs include white cottony residue at nodes and subtle softening of pearls.

Alcohol swabs work because isopropyl alcohol dissolves the insect’s protective coating, killing it on contact.

Dousing the entire plant without targeting pests damages tissue and should be avoided. Isolation matters because mealybugs spread easily.

Root rot pathogens thrive under hypoxic conditions created by overwatering. Once rot is advanced, cutting losses is sometimes the most responsible choice.

Integrated pest management guidance from university extension services such as the University of California IPM program provides realistic expectations for control without theatrics.

Propagation & Pruning

Curio rowleyanus propagates with an enthusiasm that feels almost smug, which is fortunate because pruning is not optional if the plant is expected to look intentional rather than like a failed science experiment dangling from a hook.

Each strand is made of repeating nodes, which are the slightly thickened points where pearls attach to the stem. A node is not just a decorative joint.

It contains dormant meristematic tissue, meaning cells that can switch careers and become roots when given the chance.

That biological flexibility is why a single healthy strand can turn into an entirely new plant with very little effort and absolutely no mysticism.

Cuttings root easily because the stems are already designed to store water and survive brief interruptions in supply. When a strand is cut, the exposed end needs time to form a callus, which is a thin layer of dried tissue that seals the wound.

Skipping this step and pushing a fresh, wet cut into soil invites bacteria and fungi to enter the stem, which usually ends in a soft, foul-smelling collapse that no amount of optimism will fix. Letting the cut end sit out for a day or two in a dry, shaded spot gives the plant time to protect itself.

This is not about being precious. It is about preventing rot.

The most reliable propagation method is simply laying strands on the surface of dry, gritty soil and pinning them gently so the nodes make contact. Roots emerge from those nodes because the plant reads contact with a stable surface as an opportunity rather than a threat.

Burying the strands deeply is a common mistake that cuts off airflow and keeps the stem too wet. The result is decay before roots have time to form.

Light misting after roots appear is fine, but soaking the soil before that point usually turns the cutting into compost.

Seed propagation exists in theory and is irrelevant in practice. Indoor plants rarely flower, viable seed is uncommon, and even when seeds exist, they are slow and unpredictable.

Anyone attempting this route is doing it for curiosity rather than results.

For a home plant buyer who wants a fuller pot, cuttings are the only sane option.

Pruning improves fullness because removing long, leggy strands forces the plant to redirect energy into dormant nodes closer to the soil surface. This creates more growing points and a denser crown.

What not to do is hack the plant repeatedly out of guilt or boredom.

Excessive pruning removes stored water and stresses the plant, slowing recovery. One thoughtful trim during active growth is useful. Constant interference is not.

Diagnostic Comparison Table

The popularity of Curio rowleyanus has inspired endless confusion with other trailing plants that share a vaguely charming cascade but behave very differently once they enter a home. Visual similarity is not biological similarity, and assuming care overlaps is how perfectly healthy plants end up dying out of spite. Comparing it with Peperomia tetraphylla and Dischidia ruscifolia clears up most misunderstandings before they become expensive.

Plant	Growth Type	Water Storage Strategy	Light Tolerance	Toxicity Profile
Curio rowleyanus	Trailing succulent	Spherical leaves storing water	Bright indirect with gentle sun	Contains pyrrolizidine alkaloids
Peperomia tetraphylla	Trailing semi-succulent	Fleshy leaves, shallow storage	Medium to bright indirect	Generally considered non-toxic
Dischidia ruscifolia	Epiphytic vine	Thin leaves, minimal storage	Bright filtered light	Non-toxic

Curio rowleyanus survives neglect better than attention because its pearls function as reservoirs. That same adaptation makes it intolerant of frequent watering. Peperomia tetraphylla stores some moisture but still expects more regular hydration, and treating it like a cactus results in limp, disappointed foliage.

Dischidia ruscifolia relies on consistent airflow and light moisture because it evolved clinging to trees, not sitting in pots of soil pretending to be a desert plant.

Toxicity is where the differences matter most for pet households. Curio rowleyanus contains pyrrolizidine alkaloids, which can cause cumulative liver damage if ingested. Peperomia and Dischidia lack this specific risk and are often chosen as safer substitutes.

Assuming all trailing plants are equally dangerous or equally safe ignores chemistry and leads to bad decisions.

Watering tolerance also diverges sharply.

Overwatering Curio rowleyanus kills it quickly by suffocating roots, while slight underwatering barely registers. Overwatering Dischidia is less immediately fatal but leads to chronic decline. Treating these plants interchangeably because they all look nice on a shelf is an efficient way to lose all of them.

If You Just Want This Plant to Survive

Survival with Curio rowleyanus is about restraint, not skill. The plant does not reward constant checking, misting, rotating, or emotional hovering.

It rewards stable conditions and long stretches of being left alone. Minimalist care works because the plant’s physiology is built around conserving resources, not responding to frequent input.

Stable light placement matters more than chasing perfection. Once the plant finds a bright spot with indirect light and perhaps a little gentle morning sun, moving it repeatedly in search of better angles only disrupts its internal rhythms. Plants do not enjoy redecorating.

They adapt slowly, and each move forces a recalibration that uses stored energy.

Leave it where it works and resist the urge to improve what is already acceptable.

Watering discipline is where most failures happen.

Waiting until the soil is completely dry feels wrong to people used to leafy houseplants, but succulents operate on a different timeline.

Watering early keeps the roots constantly damp, cutting off oxygen and inviting rot.

Dry soil allows gas exchange around the roots, which is just as important as moisture.

The plant does not need encouragement.

It needs patience.

Ignoring cosmetic panic responses is part of the deal. A slightly shriveled pearl does not mean the plant is dying. It means it is using stored water as intended.

Rushing to fix that with a watering can often creates the real problem.

Conversely, firm, glossy pearls are not a signal to water more. They are a signal to stop.

Hanging plants are often forgotten plants, and that is exactly why this one survives in so many homes. Being slightly out of reach prevents impulsive watering and constant touching. What not to do is bring it down weekly for inspection and adjustment.

That kind of attention satisfies human anxiety, not plant biology.

Buyer Expectations & Long-Term Behavior

Curio rowleyanus grows at a moderate pace when conditions are right and stalls quietly when they are not. Expecting rapid trailing within weeks sets up unnecessary disappointment.

Early growth often focuses on root establishment and thickening existing strands rather than dramatic length. This is normal and does not require intervention.

Seasonal pauses are part of the plant’s behavior. Growth typically slows during lower light months, even indoors, because light intensity drives photosynthesis more than temperature.

Adding water or fertilizer during these pauses does not restart growth and usually causes damage. The plant is resting, not waiting for motivation.

Strand density changes over time. Older strands may thin or drop pearls near the crown as resources are redirected to new growth.

This does not mean the plant is failing.

It means it is aging like any living system. Pruning and re-rooting cuttings refresh the plant and maintain fullness, but expecting permanent perfection is unrealistic.

Six months of care produces a plant that looks settled.

Two years of consistent conditions produce a plant that looks confident.

Longevity is measured in years, not seasons, when the plant is not drowned or starved. Sudden relocations, especially from bright light to dim corners, trigger stress responses that take months to resolve. What not to do is move the plant repeatedly and blame it for reacting.

New Buyer Guide: How to Avoid Bringing Home a Lemon

Buying Curio rowleyanus requires looking past surface beauty. Firm pearls are a good sign, but firmness alone is not enough.

Gently squeezing a few pearls near the soil line tells more than admiring the trailing ends. If the base feels soft or hollow, rot may already be working its way upward.

Checking soil dryness matters because retail plants are often overwatered to survive shipping and display. Soil that feels cool and wet days after arrival suggests poor drainage and stressed roots.

Taking home a plant like that and watering it again is a reliable way to kill it.

Stem integrity matters more than length. Healthy stems feel springy and resilient. Brittle, translucent stems indicate dehydration or rot, both of which are difficult to reverse.

Inspecting at the soil line also reveals pests like mealybugs, which hide where stems meet soil and go unnoticed until the plant declines.

Fresh-looking pearls can hide rot because succulent tissue masks early damage. The plant may look fine while roots are already compromised. What not to do is assume visual appeal equals health.

Asking when the plant was last watered and refusing specimens sitting in soggy soil reduces risk significantly.

Blooms & Reality Check

Curio rowleyanus can produce small, white, daisy-like flowers with elongated stamens and a faint cinnamon-like scent. When they appear, they are charming in a quiet, understated way rather than dramatic. Indoors, blooms are uncommon because they require a combination of mature growth, strong light, and seasonal cues that most homes do not provide.

Foliage is the point of this plant.

Chasing flowers leads to overfertilization and excessive watering, both of which harm the plant. Fertilizer cannot force flowering safely because bloom initiation depends on light and internal energy reserves, not nutrient abundance.

Adding more nutrients than the plant can use leads to salt buildup in the soil, which damages roots.

When blooms do appear, they are brief and do not transform the plant’s appearance. Treat them as a bonus, not a goal.

What not to do is adjust care dramatically in hopes of repeat performances. Stability supports health.

Manipulation invites decline.

Is This a Good Plant for You?

Curio rowleyanus is moderately difficult, not because it requires complex care, but because it punishes common houseplant habits. The biggest failure point is overwatering driven by good intentions. People who enjoy fussing, misting, and weekly schedules struggle with this plant.

It suits households that prefer attractive, low-interaction plants and can provide bright light. It does poorly in dim apartments where windows are more decorative than functional.

Pet owners should be cautious, as ingestion poses a real risk, especially for curious cats.

Those willing to accept that doing less is often better will find it rewarding.

Those who need constant feedback and visible progress may find it irritating.

Avoiding it is sensible if pets chew plants or if light is limited.

FAQ

Is String of Pearls easy to care for?

It is easy if restraint comes naturally. The care itself is simple, but resisting the urge to water frequently is where many people fail. Understanding that neglect is sometimes appropriate makes it manageable.

Is Curio rowleyanus toxic to pets?

Yes, ingestion can cause cumulative liver damage due to pyrrolizidine alkaloids. Small nibbles may not cause immediate symptoms, which is why the risk is often underestimated. Keeping it out of reach is essential.

How fast does String of Pearls grow?

Growth is moderate and depends heavily on light. In bright conditions, strands lengthen steadily, while in lower light the plant focuses on survival rather than expansion. Sudden growth spurts are rare.

How often should it be watered?

Only after the soil dries completely. This often means weeks rather than days, depending on light and season. Watering on a schedule rather than in response to soil dryness is a common mistake.

Can it grow in low light?

It can survive for a time, but growth becomes weak and stretched. Low light reduces photosynthesis, leading to elongated internodes and sparse pearls. Survival is not the same as thriving.

Why are my pearls shriveling even though I watered?

Shriveling after watering often indicates root damage. If roots cannot absorb water due to rot, the plant continues to dehydrate despite wet soil. Adding more water worsens the problem.

Does it flower indoors?

Occasionally, but not reliably. Indoor conditions rarely mimic the seasonal cues needed for flowering. Healthy foliage is a more realistic expectation.

Can String of Pearls recover from root rot?

Recovery is possible only if healthy stems remain. Removing affected roots and re-rooting cuttings is more effective than trying to save damaged roots. Waiting too long reduces chances.

Is there a safe alternative for pet owners?

Yes, plants like Peperomia tetraphylla or Dischidia ruscifolia offer a similar trailing look without known toxicity. They still require appropriate care, but ingestion risk is lower.
