Colocasia
Colocasia brings oversized elephant-ear leaves and a watering rhythm closer to thirsty tropicals than typical houseplants. It fits bright, warm spaces where regular watering is realistic and big leaf mass is the whole point.
About Our Filters
Filters help you narrow things down fast and without guessing. We put a lot of time and effort into keeping filter values consistent across the shop by cross-checking references and validating them against real-world indoor growing and handling.
Use them as guidance, not guarantees. Homes vary a lot, so for the full context (and any exceptions), open the product page and read the description.
How filtering works
- Filters stack: each selection narrows results.
- Multiple picks in one filter are usually either/or within that filter.
- Undo anytime: click a selected option again (or clear filters).
Safety
- Non-toxic: not known for relevant chemical toxicity for common pets (chewing can still cause irritation).
- Non-toxic & Pet Friendly: stricter shortlist that also avoids many physical hazards like spines, sharp tips, thorns, and bristles.
Common care filters
- Light level: Low indirect → Full sun/direct.
- Water Needs: Low / Medium / High.
- Humidity Level: Normal (40–50%) / Moist (50–60%) / Humid (60–80%+).
Growth & size
- Growth Habit: climbing, trailing, crawling, upright, self-heading, clumping, rosette.
- Needs support? none / optional / needed.
- Delivered size: pot size + plant height at shipping.
- Max size indoors: realistic long-term height + spread indoors.
Looks & botanical browsing
- Leaf Shape & Size + Foliage Colour: quick visual categories.
- Plant Type / Genus / Family: browse by broad group or taxonomy.
If you want to see the references we use, Plant Care Resources is simply a curated list of source links (POWO, Kew, and more).

Colocasia: thirsty elephant ears indoors
- Growth style: tuber-forming aroid built for big leaves and heavy water use in warmth; demands space and attention.
- Light: bright, indirect light or gentle sun; low light flops leaves, strong glass sun burns broad blades quickly.
- Water: likes consistently moist, well-aerated mix; hates being baked dry but also resents cold, stagnant soil.
- Substrate: responds well to rich, structural aroid mix that drains fast but does not collapse around the tuber.
- Climate: warm conditions and reasonable humidity keep new leaves coming; cool, wet periods often trigger dieback.
- Toxicity: raw tubers and leaves are irritant; treat strictly as ornamental indoors.
Colocasia is an accepted genus in Araceae native to tropical and subtropical Asia. It includes taro and allied elephant ears, with species adapted to warm, moisture-rich habitats.
Colocasia: elephant ears for big leaves and bold, tropical scale
Moisture, warmth and feeding drive the show
Colocasia builds dramatic, upright stems topped with broad “elephant ear” leaves. It’s a strong choice for bright rooms where a plant can take up space and be watered regularly.
Colocasia prefers consistently moist substrate and benefits from a nutrient‑rich mix. When light is high and temperatures stay warm, growth can be fast and lush.
Cool nights and low light can slow it down, and some plants pause growth for a while. Fresh growth returns once conditions improve.
- Light: Bright indirect light to a few hours of gentle sun; darker-leaved types often need more light indoors.
- Watering: Keep the mix evenly moist; reduce frequency if temperatures drop and growth slows.
- Feeding: Regular, balanced nutrition supports leaf size and colour; flush occasionally to prevent salt build-up.
- Pot and mix: A stable pot and airy, moisture‑retentive substrate help prevent tipping and dry pockets.
- Common issues: Spider mites in dry air and root stress in compact mixes; check regularly and keep airflow steady.

Frequently Asked Questions About Colocasia
What kind of plant is Colocasia indoors?
Colocasia is a large elephant-ear aroid grown mainly for bold leaves. Indoors, it is usually a statement plant rather than a compact shelf plant, and it needs more light, water, and root room than many common houseplants.
What light does Colocasia need indoors?
Very bright light is the baseline, and some gentler direct sun or filtered sun is often helpful indoors. Colocasia is not a low-light plant, but leaves can still scorch in harsh all-day glass without acclimation.
How should I water Colocasia?
In active growth, do not let more than roughly the top 5–15% of the pot dry before watering again. Colocasia is much less tolerant of dry-downs than most houseplants, but the pot should still drain freely and not stay stagnant.
Why does Colocasia droop or crisp so quickly indoors?
Because it is a fast, moisture-loving tropical grower. Cold roots, weak light, dry substrate, or a sudden drop in humidity can show up quickly as drooping, edge crisping, or stalled growth.
Are Colocasia safe around pets?
No. Colocasia are toxic to cats and dogs because they contain insoluble calcium oxalate crystals.

Die Pflanzen waren prima verpackt und ein heatpack war im Paket enthalten. Die Lieferzeit hat 2 bis 3 Tagen gedauert, was aus meiner Sicht wirklich gut ist. Alle drei Pflanzen haben die Lieferung gut überstanden. Ich habe mich auf Hoyas spezialisiert und habe schon die nächsten Pflanzen meiner Wunschliste auf der Website gefunden. Daher wird die nächste Bestellung nicht lange auf sich warten lassen.

The plants are carefully packaged and arrive in great conditions (I’m based in Spain) and they’re always there to help in any way they can with your purchase.I have and will always recommend Foliage Factory to every friend I can. I’m not only satisfied with their plants and prices, but their customer service is exceptional.

Very healthy and well packed plant. Unfortunately there was one plant that ordered couldn’t be delivered as it was out of stock hence 1 star less.

Die Sendung kam leider in keinem guten Zustand bei mir an, kann passieren. Habe mich darauf hin sofort an Foliage Factory gewandt und habe selten einen so guten, schnellen, freundlichen und kulanten Kundendienst erlebt.

Everything arrived in good condition and very well packed - it wasn't easy with a fragile plant and a heavy bag of substrate. I recommend it!

Bester online-Pflanzenhandel den ich kenne (habe davor 4 andere ausprobiert). Eine teure Pflanze wurde beim Transport beschädigt und mir ersetzt. Der Kontakt dabei war auch sehr nett (danke Jan) und hat mir gut geholfen. Die anderen Pflanzen sind in einem sehr guten Zustand, keine Schädlinge, super Bewurzelung. Nur zu empfehlen! :)

The plants have arrived in perfect condition, the roots and the foliage so so healthy! I had problem with 1 plant out of 16 and they have responded to my email almost instantly and the issue was resolved straight away. I'm really impressed and satisfied, definitely getting more plants from them again!

I received perfectly heathy and absolutely beautiful plants, even bigger than expected. The delivery within Europe was really fast. I think Foliage Factory has one of the best plant web shops in the internet. It‘s just great to get so much informations about the plants. I will definitely order again :)
