Melissa's Houseplant Field Guide

Plant Care Compendium

A specimen-by-specimen reference for the collection β€” light, water rhythm, feeding, propagation, and the mistakes worth avoiding.

Batch 1 of 4  Β·  Genera Aglaonema β†’ Colocasia  Β·  19 specimens
β—† CR context Costa Rica's warm, humid, bright-shade climate suits most aroids well outdoors on covered patios; the real risks indoors are AC-dried air and overwatering during the May–November rainy season.

Aglaonema

Araceae Β· Chinese Evergreen

A tough, slow-growing understory aroid genus from tropical Asia, prized for patterned foliage. Red and pink cultivars need noticeably more light than green ones to hold their color.

AGL-01Araceae

Red Aglaonema

Aglaonema commutatum hybrids (Red Gold / Siam Aurora group)

LightBright, indirect β€” closer to a window than typical aglaonemas
Humidity50–60%, tolerates average room air
Water cycleLet top 3–4cm dry; water thoroughly, discard runoff

Botanical notes

Rhizomatous, cane-forming aroid; the red/pink pigment is anthocyanin, which fades in low light and intensifies with brighter, filtered sun.

Soil & moisture

Chunky, fast-draining aroid mix (bark, perlite, peat/coco coir). Never let it sit in standing water β€” the rhizome rots quickly. Slightly drier between waterings than a Philodendron.

Fertilizing

Balanced liquid fertilizer at quarter strength every 4 weeks whenever the plant is actively pushing new growth β€” in Costa Rica's stable warmth that's often close to year-round. Taper off or skip during the driest stretch of dry season (roughly December–April) if watering β€” and therefore feeding β€” naturally slows.

Common mistakes

  • Keeping it too shaded β€” color fades to plain green
  • Cold water or cold drafts causing translucent, mushy patches
  • Overwatering the dense root mass, especially in low-light spots

Propagation

Divide offsets/rhizome sections at repot, ensuring each division has roots. Stem cuttings with a node also root readily in water or moist perlite.

CR note

Give it your brightest non-direct spot β€” east-facing windows work well. During heavy rain-season humidity, extend the dry-down window slightly to avoid rhizome rot.

Alocasia

Araceae Β· Elephant's Ear

Rhizomatous tropical aroids from Southeast Asian rainforest floors β€” dramatic foliage, high humidity needs, and a tendency toward dormancy or leaf drop when conditions dip below their comfort zone. Spider mites are the main pest to watch.

ALO-05Araceae

Alocasia Dragon's Breath

Alocasia heterophylla 'Dragon's Breath'

LightBright, indirect β€” no direct sun
Humidity60–70%
Water cycleTop 2–5cm dry; keep consistently moist, never soggy

Botanical notes

Elongated, silvery-blue-green leaves with a dramatic, well-defined sinus and prominent veins that flush red to pink β€” the "breath" the name refers to. Leaves can reach 60–90cm at maturity.

Soil & moisture

Well-draining, rich aroid mix. Sensitive to both prolonged dryness and waterlogging β€” aim for the same steady middle ground as its Alocasia relatives.

Fertilizing

Half strength balanced fertilizer every 4–6 weeks during active growth.

Common mistakes

  • Cold drafts or sudden temperature swings causing leaf drop
  • Low humidity dulling the red vein color and crisping edges
  • Overwatering in a mix that isn't chunky enough

⚠ Pet safety

Toxic to cats and dogs (calcium oxalate crystals), same as other Alocasia.

Propagation

Rhizome/corm division at repot, same as other Alocasia in this collection.

CR note

A strong candidate for a bright, humid indoor corner β€” Costa Rica's ambient humidity helps keep the vein color vivid without extra effort.

ALO-01Araceae

Alocasia Frydek (incl. "Lagar" form)

Alocasia micholitziana 'Frydek'

LightBright, filtered β€” no direct sun
Humidity60–75%, comes naturally in Costa Rica's climate
Water cycleTop 2–3cm dry; keep evenly moist, never soggy

Botanical notes

Velvety, deep-green arrow-shaped leaves with striking white-green venation. "Lagar" is essentially the same cultivar sold under a nursery/regional name β€” care is identical.

Soil & moisture

Airy aroid mix with extra perlite/orchid bark for drainage. Consistency matters more than either extreme β€” avoid full dry-outs and avoid waterlogging equally.

Fertilizing

Quarter-to-half strength balanced fertilizer every 3–4 weeks during active growth; pause if the plant shows any dormancy signs (see below).

Common mistakes

  • Low humidity causing crispy leaf edges
  • Panicking at natural dormancy β€” a leaf or two dying back while a new one emerges is normal
  • Direct sun bleaching the velvet leaves

Propagation

Divide rhizome offsets/pups at the base during repotting, keeping roots intact on each division. Avoid leaf cuttings β€” Alocasia won't propagate from a leaf alone.

CR note

Ambient humidity indoors is usually enough without extra misting; the bigger threat is air-conditioned rooms drying it out β€” group with other humidity lovers away from AC vents.

ALO-02Araceae

Variegated Alocasia "Hilo Beauty"

Alocasia 'Hilo Beauty'

LightBright, indirect; variegation needs more light than solid-green Alocasia
Humidity60%+
Water cycleEvenly moist; top 2cm dry between waterings

Botanical notes

Compact grower with cream-and-green marbled, ruffled leaves. Naturally has smaller, less vigorous growth than solid-colored relatives due to reduced chlorophyll in the pale sections.

Soil & moisture

Very well-draining chunky mix β€” variegated sections are more prone to rot-related stress if the soil stays wet too long.

Fertilizing

Light feeding, quarter strength monthly in growing season β€” variegated tissue can burn more easily than green tissue.

Common mistakes

  • Expecting the same growth speed as a full-green Alocasia
  • Fertilizing at full strength and scorching pale leaf sections
  • Letting humidity drop below 50% β€” leaf edges brown fast

Propagation

Rhizome division only, at repot. Choose divisions with a healthy amount of green tissue for reliable establishment.

CR note

A covered, bright patio spot with dappled light is ideal for the growing season; bring indoors if nighttime temps drop unusually low in higher-elevation areas.

ALO-06Araceae

Alocasia Jacklyn

Alocasia tandurusa (syn. 'Sulawesi Jacklyn')

LightMedium to bright, indirect
HumidityAbove-average preferred; tolerates ~40% reasonably well
Water cycleTop 3–5cm dry between waterings

Botanical notes

A recent introduction from Sulawesi, Indonesia β€” deeply lobed leaves in layered hues of green, finely textured with small hairs, on creamy petioles streaked in purple. Interesting from the side as well as from above, unlike most Alocasia.

Soil & moisture

Airy, chunky aroid mix. More rot-prone than it looks β€” this is a common overwatering trap since the deeply lobed leaves make it look thirstier than it is.

Fertilizing

Diluted balanced fertilizer monthly during active growth.

Common mistakes

  • Overwatering out of caution, since the plant looks delicate
  • Cold drafts or temperature swings causing rapid leaf shrinkage
  • Low light causing legginess

⚠ Pet safety

Toxic to cats and dogs (calcium oxalate crystals), same as other Alocasia.

Propagation

Rhizome division at repot, same as other Alocasia in this collection.

CR note

Stable year-round warmth in Costa Rica suits this one well β€” it dislikes temperature swings far more than most Alocasia, and CR's climate avoids that problem entirely indoors.

ALO-07Araceae

Alocasia Melo

Alocasia baginda 'Melo'

LightBright, indirect
Humidity65–80%
Water cycleDries predictably between waterings β€” let it dry more than a typical Alocasia

Botanical notes

A jewel Alocasia from the same Borneo species group as 'Silver Dragon' and 'Dragon Scale' (also sold as Alocasia rugosa). Thick, textured, compact leaves and slow, corm-based growth β€” a genuinely different growth habit from the larger, faster Alocasia in this collection.

Soil & moisture

Very chunky, fast-draining mix. The corm rots quickly if kept wet β€” this genus tolerates dryness far better than it tolerates excess moisture.

Fertilizing

Light feeding, quarter strength, every 4–6 weeks β€” a slow grower with modest needs.

Common mistakes

  • Watering on the same schedule as a faster-growing Alocasia, causing corm rot
  • Expecting quick growth from a genuinely slow, corm-based plant
  • Low humidity causing crisping on the thick leaves

⚠ Pet safety

Toxic to cats and dogs (calcium oxalate crystals), same as other Alocasia.

Propagation

Corm offsets at repot β€” separate once a division has its own roots.

CR note

Given its slow, corm-based habit, resist the urge to water this one as often as your faster Alocasia β€” CR's humidity handles the air side, but the soil should still dry more than you'd expect.

ALO-08Araceae

Alocasia Nobilis

Alocasia sanderiana 'Nobilis'

LightBright, indirect
Humidity60%+
Water cycleTop 2–3cm dry; keep evenly moist

Botanical notes

Large, glossy, deeply lobed arrowhead leaves in dark green with prominent silvery-white veins and sharply pointed edges β€” a cultivar of Alocasia sanderiana, native to Southeast Asian rainforests.

Soil & moisture

Well-draining, organically rich aroid mix. Let it dry almost fully between waterings β€” more drought-tolerant than most Alocasia here.

Fertilizing

Quarter strength balanced fertilizer monthly during active growth.

Common mistakes

  • Overwatering β€” this one wants a drier rhythm than Frydek or Polly
  • Direct sun dulling the leaf's slightly metallic sheen
  • Too little light causing slower growth and paler veining

⚠ Pet safety

Toxic to cats and dogs (calcium oxalate crystals), same as other Alocasia.

Propagation

Division or stem cuttings with a node, at repot.

CR note

One of the more drought-tolerant Alocasia here β€” good for a bright spot where you're less likely to check on watering daily.

ALO-09Araceae

Alocasia Pink

Alocasia longiloba 'Pink Dragon'

LightBright, indirect
Humidity60–70%
Water cycleTop 5cm dry; similar rhythm to Polly

Botanical notes

Glossy dark green leaves with prominent silvery veins and a purplish-maroon underside, on standout bright pink petioles and stems β€” the feature that gives it its name. Growth habit is similar to Alocasia Polly, also in this collection.

Soil & moisture

Well-draining aroid mix; keep evenly moist without letting it sit wet. More cold-sensitive than most β€” it can lose leaves (and even go dormant, resting on its corm) if temperatures drop, though this is rarely a concern indoors in Costa Rica.

Fertilizing

Quarter strength balanced fertilizer monthly during active growth.

Common mistakes

  • Overwatering the thick, sensitive roots
  • Assuming a defoliated plant is dead β€” the corm often just needs a rest before resprouting
  • Too little light muting the pink stem color

⚠ Pet safety

Toxic to cats and dogs (calcium oxalate crystals), same as other Alocasia.

Propagation

Division of offsets/corm sections at repot.

CR note

The cold-triggered dormancy this plant is known for elsewhere is unlikely to show up in Costa Rica's stable indoor warmth β€” expect steadier, more consistent growth than temperate-climate guides describe.

ALO-03Araceae

Alocasia Polly

Alocasia Γ— amazonica 'Polly'

LightBright, indirect
Humidity60–70%
Water cycleTop 2–3cm dry; consistent moisture

Botanical notes

A hybrid known for glossy, arrow-shaped leaves with pale green veins and wavy white-edged margins. Often the "starter" Alocasia for new growers β€” slightly more forgiving than Frydek. Also sold as "Alocasia Amazonica" β€” that name refers to the same amazonica hybrid group 'Polly' belongs to, and in the trade the two names are used interchangeably for what is, for care purposes, the same plant.

Soil & moisture

Chunky aroid mix; likes to dry slightly at the surface but never fully. Terracotta pots help regulate moisture in humid climates.

Fertilizing

Quarter strength every 3–4 weeks in active growth; withhold entirely once dormancy signs appear.

Common mistakes

  • Treating seasonal dieback as plant failure and overwatering to "fix" it
  • Spider mites from air that's too dry β€” inspect leaf undersides regularly
  • Cold shock from AC or night drafts

Propagation

Divide corm/rhizome offsets at the base; each division needs at least one growth point and some roots.

CR note

Reliable year-round grower in typical CR indoor warmth; watch for mite pressure in drier Guanacaste-type microclimates specifically.

ALO-10Araceae

Alocasia Scalprum

Alocasia scalprum

LightBright, indirect
Humidity60–80%
Water cycleTop 2–3cm dry between waterings

Botanical notes

Nicknamed the "Scalpel Plant" β€” narrow, blade-like, matte blue-green leaves with a leathery texture and pronounced ridged veins, growing from a central rhizome. Stays compact, typically under 45cm indoors. Native to the Philippines.

Soil & moisture

Well-draining aroid mix; consistent moisture without staying soggy.

Fertilizing

Quarter strength balanced fertilizer every 4–6 weeks during active growth.

Common mistakes

  • Overwatering, given its already-compact water needs
  • Direct sun scorching the matte leaf surface
  • Tap water sensitivity causing leaf-edge browning β€” filtered or rain water is safer

⚠ Pet safety

Toxic to cats and dogs (calcium oxalate crystals), same as other Alocasia.

Propagation

Rhizome division at repot.

CR note

Its compact size makes it a good fit for shelf space rather than floor space β€” and like the Goeppertia in Batch 2, it'll appreciate Costa Rica's soft rainwater over tap.

ALO-04Araceae

Variegated Elephant Ear

Alocasia macrorrhizos 'Variegata'

LightBright, indirect to gently filtered direct morning sun
Humidity55–70%
Water cycleKeep evenly moist; slightly more water-tolerant than smaller Alocasia

Botanical notes

A large-growing species with heavily marbled cream-and-green leaves that can reach substantial size given room and light β€” the largest-growing Alocasia in this collection.

Soil & moisture

Rich but fast-draining mix; as a bigger, more vigorous grower it can handle slightly more consistent moisture than compact Alocasia cultivars.

Fertilizing

Half strength balanced fertilizer every 3 weeks in active growth given its size and vigor; reduce in cooler/drier months.

Common mistakes

  • Underestimating eventual size and under-potting
  • Too little light causing loss of variegation and leggy growth
  • Letting it dry out completely, which stresses this species more than others

Propagation

Rhizome/offset division at repot; large enough specimens can also be propagated from sizeable rhizome sections with an eye.

CR note

A strong candidate for a bright, covered outdoor patio spot in Costa Rica's climate β€” it can take more sun and humidity outdoors than most of its Alocasia relatives.

Anthurium

Araceae Β· Flamingo Flower / Velvet Anthurium

A huge genus split into two very different houseplant camps: flowering types grown for their glossy waxy spathe, and "velvet" foliage types grown by collectors for thick, textured, dramatically-veined leaves. This entry covers the velvet/collector type.

ANT-01Araceae

Anthurium Dorayaki

Anthurium crystallinum Γ— A. clarinervium 'Dorayaki'

LightBright, indirect β€” no direct sun
Humidity60–80%
Water cycleTop 3–5cm dry; consistently moist, never soggy

Botanical notes

An Indonesian-bred hybrid crossing two collector favorites β€” nearly circular, thick, velvety dark green leaves with prominent silvery-white veins, named for their resemblance to the round Japanese pancake. Compact, self-heading habit; genuinely slow-growing.

Soil & moisture

Very chunky, airy aroid mix (bark, perlite, coco coir) β€” good aeration matters more than moisture retention. Water thoroughly, then let it dry meaningfully before the next round.

Fertilizing

Quarter strength balanced fertilizer monthly during active growth β€” light feeding for a slow grower.

Common mistakes

  • Overwatering in a mix that isn't airy enough, causing root rot
  • Low humidity causing crispy, browning edges on the velvet leaves
  • Direct sun scorching the delicate leaf surface

⚠ Pet safety

Toxic to cats and dogs (calcium oxalate crystals) if chewed β€” moderate irritation, similar to other aroids in this collection.

Propagation

Stem cuttings with a node, or division of offsets at repot β€” either works, though this cultivar is slow to establish either way.

CR note

A genuinely good fit for Costa Rica's humidity β€” one of the easier velvet Anthuriums to keep happy without a dedicated humidity cabinet, given how close ambient conditions already sit to what it wants.

Beaucarnea

Asparagaceae Β· Ponytail Palm

Not a true palm β€” a caudex-forming succulent from semi-arid Mexico. The polar opposite of the Alocasia above: full sun, minimal water, and near indestructibility.

BEA-01Asparagaceae

Ponytail Palm

Beaucarnea recurvata

LightFull sun to bright indirect β€” the brighter the better
HumidityLow, average room humidity is fine
Water cycleLet soil dry fully; water sparingly, more like a succulent

Botanical notes

The swollen base (caudex) stores water, allowing long drought tolerance. Slow-growing, with a cascade of strappy leaves from the top of the stem.

Soil & moisture

Cactus/succulent mix with sharp drainage β€” the single biggest killer of this plant is a mix that holds moisture around the caudex.

Fertilizing

Light feeding 2–3 times during the growing season with a diluted balanced or cactus fertilizer; it needs very little.

Common mistakes

  • Watering on a fixed schedule instead of by soil dryness
  • Using regular potting soil instead of a gritty, fast-draining mix
  • Too little light causing thin, floppy, pale leaves

Propagation

Occasionally produces basal offsets/pups that can be removed with some root and potted separately once large enough. Seed propagation is slow and less practical at home.

CR note

Perfect for the sunniest, driest spot in the house or a bright patio β€” one of the few plants on this list that actively benefits from CR's intense midday sun.

Begonia

Begoniaceae Β· Angel Wing / Cane Begonia

A huge family of over a thousand species, but the cane-forming "angel wing" types like this one share a fairly consistent profile: bright indirect light, evenly moist soil, and a fussiness about humidity that's easily solved in a naturally humid climate.

BEG-01Begoniaceae

Begonia maculata (Polka Dot Begonia)

Begonia maculata

LightBright, indirect β€” no direct sun
Humidity50%+
Water cycleTop 2–3cm dry; keep evenly moist, never soggy

Botanical notes

Large, angel-wing-shaped olive-green leaves marked with silvery-white spots, deep red on the underside β€” the redder the underside, the more light it's getting. Cane-forming, bamboo-like jointed stems. Native to Brazil's Atlantic rainforest.

Soil & moisture

Well-draining mix that still holds some moisture. Consistency matters more than either extreme β€” this genus is prone to both root rot from soggy soil and leaf drop from drying out.

Fertilizing

Light balanced feeding monthly during active growth.

Common mistakes

  • Watering overhead onto the leaves, inviting powdery mildew β€” water at the soil line instead
  • Too little light causing legginess and faded spot pattern
  • Letting it get root-bound and leggy without regular pruning

⚠ Pet safety

Toxic to cats and dogs if chewed β€” begonias contain soluble calcium oxalates concentrated in the roots/tubers, causing oral irritation and GI upset.

Propagation

Extremely easy from stem cuttings in water β€” a classic beginner-friendly propagation, and a good way to keep a fuller-looking plant as the canes age and thin at the base.

CR note

CR's ambient humidity does most of the work this plant usually needs a humidifier for elsewhere β€” just make sure airflow is decent given how humid it already is, since stagnant damp air combined with overhead watering is what actually invites mildew.

Caladium

Araceae Β· Angel Wings

Tuberous aroids grown for paper-thin, vividly patterned leaves. Distinctive trait: they naturally go dormant, dying back to the tuber, and this is normal β€” not a care failure.

CAL-01Araceae

Caladium bicolor 'White Queen'

Caladium bicolor 'White Queen'

LightBright, indirect; some morning sun tolerated
Humidity60%+, thin leaves crisp easily in dry air
Water cycleEvenly moist during active growth; nearly dry during dormancy

Botanical notes

Pale, near-white leaves with deep green veining, arising from an underground tuber. Growth is seasonal β€” active flush of leaves, then natural dieback.

Soil & moisture

Rich, well-draining mix. Keep consistently moist while leaves are actively growing; once leaves yellow and collapse at season's end, cut back watering drastically.

Fertilizing

Balanced liquid fertilizer at quarter strength every 3–4 weeks only while actively leafing out; none during dormancy.

Common mistakes

  • Discarding the plant when it dies back, not realizing the tuber is still alive
  • Continuing to water heavily through dormancy, rotting the tuber
  • Too little humidity causing the delicate leaves to crisp at the edges

Propagation

Divide tubers (each with at least one visible "eye") during the dormant period and replant to start the next growth cycle.

CR note

In Costa Rica's stable warm climate, dormancy can be shorter or less pronounced than in temperate growing guides β€” let the plant's own leaf behavior guide watering rather than a strict calendar.

CAL-02Araceae

Caladium bicolor 'Bombshell'

Caladium bicolor 'Bombshell'

LightBright, indirect
Humidity60%+
Water cycleEvenly moist in growth; dry down through dormancy

Botanical notes

A compact, ruffled-leaf cultivar in fiery red tones, smaller and more densely leaved than many Caladium β€” good for tighter spaces. Same tuberous, dormancy-driven lifecycle as 'White Queen'.

Soil & moisture

Same profile as 'White Queen': rich, moisture-retentive but well-draining mix during growth, kept nearly dry during dormancy.

Fertilizing

Quarter strength balanced fertilizer every 3–4 weeks in active growth; stop feeding as leaves begin to decline naturally.

Common mistakes

  • Assuming a dying-back plant needs more water, not less
  • Direct hot sun scorching the compact ruffled leaves
  • Repotting or disturbing the tuber while it's dormant

Propagation

Tuber division at the start of dormancy or just before new growth resumes, same method as other Caladium.

CR note

Its compact size makes it well suited to a bright windowsill indoors, sidestepping the intense direct sun found on unshaded CR patios.

Callisia

Commelinaceae Β· Turtle Vine

A fast, easy trailing succulent-leaning genus related to Tradescantia β€” forgiving and quick to root from cuttings.

CAX-01Commelinaceae

Turtle Vine

Callisia repens

LightBright, indirect to a few hours of gentle direct sun
HumidityAverage room humidity is fine
Water cycleLet top half of soil dry; somewhat drought tolerant

Botanical notes

Trailing, semi-succulent stems with small rounded leaves that can blush purple-pink under strong light β€” a good hanging basket or shelf trailer.

Soil & moisture

Standard well-draining potting mix; more forgiving of both under- and over-watering than most plants on this list, but avoid prolonged soggy soil.

Fertilizing

Light balanced feeding monthly during growing season; it grows quickly enough to benefit from regular light feeding.

Common mistakes

  • Leggy, sparse growth from too little light
  • Letting cuttings get too long without pinching, leading to a thin, straggly plant
  • Root rot from pots without drainage holes

Propagation

Extremely easy β€” stem cuttings root in water or directly in moist soil within one to two weeks. Great candidate for filling out a sparse pot quickly.

CR note

Does well on a bright, part-sun patio shelf; the brighter the light, the more pronounced its purple blush.

Chamaedorea

Arecaceae Β· Parlor Palm

A true understory palm genus, several species native to Central America β€” genuinely one of the best-suited plants on this list for the region.

CHA-01Arecaceae

Parlor Palm

Chamaedorea elegans

LightLow to bright indirect β€” very shade tolerant
HumidityAverage to high; appreciates extra humidity but adapts well
Water cycleKeep lightly moist; let the top few cm dry between waterings

Botanical notes

A slow-growing, clumping understory palm native to Mexico and Central America, naturally adapted to low, filtered rainforest-floor light.

Soil & moisture

Well-draining, slightly moisture-retentive potting mix. Sensitive to both prolonged dryness and waterlogging β€” aim for steady, moderate moisture.

Fertilizing

Light balanced fertilizer at quarter strength every 4–6 weeks in growing season; palms are prone to nutrient burn, so under-fertilizing is safer than over-doing it.

Common mistakes

  • Overwatering, especially in low-light spots where the soil stays wet longer
  • Fertilizer burn from over-application, seen as brown leaflet tips
  • Tap water fluoride/salt buildup causing tip browning over time β€” filtered or rain water helps

Propagation

Division of naturally clumping offshoots at the base, each with its own roots. Seed propagation is possible but slow and less practical at home.

CR note

Genuinely native to the region's forests β€” one of the easiest, most climate-appropriate plants on this list. Rainwater collected locally is an excellent watering source for it.

Colocasia

Araceae Β· Taro / Elephant's Ear

Often confused with Alocasia, but Colocasia leaves point downward from the petiole (Alocasia points up) and this genus tolerates β€” even enjoys β€” much wetter soil, including boggy or pond-edge conditions.

COL-01Araceae

Black Magic Elephant Ear

Colocasia esculenta 'Black Magic'

LightBright, indirect to several hours of direct sun outdoors
HumidityHigh; also very tolerant of wet, humid air
Water cycleKeep consistently moist to wet β€” this genus does not want to dry out

Botanical notes

Large, heart-shaped near-black leaves on a vigorous tuberous plant; the true taro genus, historically grown as a food crop, so it's built for wet feet.

Soil & moisture

Rich, moisture-retentive soil β€” unlike most aroids here, this one tolerates poor drainage and can even be grown at a pond's edge. Indoors, a saucer that holds a little water is fine.

Fertilizing

Half strength balanced fertilizer every 3 weeks during active growth given its vigorous size and appetite; reduce as growth slows.

Common mistakes

  • Treating it like Alocasia and underwatering β€” the opposite mistake causes stress here
  • Too little light, muting the deep black-purple leaf color to green
  • Underestimating final size indoors β€” it wants to get big

Propagation

Divide the cormlets/offsets that form around the base of the main tuber; each division needs roots and a growing point.

CR note

An excellent outdoor candidate in Costa Rica β€” happy in a large pot on a rainy, bright patio where it can catch natural rainfall without you worrying about overwatering.
