How to read these values
These care values are quick reference points for indoor growing. Use them as a guide, then adjust for pot size, substrate, temperature and how quickly the substrate dries.
For more detail, read the full product description or visit our Plant Care Guides.
- Light: level and approximate lux at leaf level.
- Watering: “% dry” shows how far the substrate should dry before watering again.
- Substrate: structure, drainage, moisture retention, base material and particle size.
- Temperature: “Ideal” shows the preferred range; “Avoid below” marks the cold-stress threshold.
- Humidity: target range; steady conditions usually matter more than exact numbers.
- Growth habit: how the plant grows, such as upright, climbing, trailing, clumping or rosette-forming.
- Support: whether a stake, pole or trellis is needed, optional or unnecessary.
- Growth speed: expected pace under suitable indoor conditions; use as a guide, not a promise.
- Max size indoors: realistic long-term indoor size under good conditions.
- Toxicity & safety: irritation, toxicity or physical hazards such as spines or bristles.
- Origin & habitat: native range, hybrid background or typical habitat where relevant.
- Outdoor growing: when a potted indoor plant can be placed outside and what outdoor protection it needs.
Alocasia cf. longiloba 'Narrow'
Alocasia cf. longiloba 'Narrow' carries long, narrow blades with a very dark green upper surface, pale to silver main veins and purple undersides. The slim leaf shape and bright vein lines create a clear elongated outline above the pot.
Its care follows the needs of a warm, rhizomatous Alocasia: bright filtered light, steady moisture, air pockets around the roots and a substrate that drains before the rhizome stays saturated. Long leaves can mark at the edges when humidity, watering or light become uneven.
Dark narrow blades with silver veins
- Leaf shape: The blades are narrow and elongated, with a longiloba-like outline.
- Upper surface: Leaves are very dark green, giving the pale veins strong contrast.
- Venation: Pale to silver main veins run through the centre and primary vein network.
- Undersides: Purple leaf undersides add a second colour layer when the leaves tilt or move.
- Growth type: It grows as a rhizomatous Alocasia and needs air as well as moisture around the roots.
- Root zone: A chunky, free-draining substrate keeps the rhizome away from stagnant moisture.
Growth behaviour in the pot
Narrow blades, dark upper surfaces and pale venation define the foliage. The purple underside adds depth from side views, especially where the petioles lift the leaves above the pot.
The plant grows from a rhizomatous aroid structure, so the substrate needs to stay lightly moist while letting oxygen move through the pot. Dense soil, cold water or a pot that holds moisture for too long can stress the roots and rhizome.
Care for Alocasia cf. longiloba 'Narrow'
- Light: Give bright filtered light; direct sun can mark the dark blade surface and pale veins.
- Water: Keep moisture even, then let the upper substrate begin drying before watering again.
- Substrate: Use a chunky, free-draining aroid mix that keeps the rhizome from sitting in stagnant moisture.
- Humidity: Moderate to high humidity helps the long leaves expand smoothly.
- Temperature: Keep it warm, ideally above 18 °C, with stable conditions around the pot.
- Potting: Move up pot sizes gradually so the roots can fill the substrate before it stays wet for too long.
Leaf signals and root stress
- Leaf-edge crisping: Long narrow leaves can brown at the edges after dry air or inconsistent watering.
- Yellowing leaves: Cold wet substrate can stress the rhizome and roots.
- Weak growth: Very low light can lead to smaller leaves and longer gaps between new growth.
- Surface marking: Direct sun or rough handling can leave marks on the dark blades.
- Spider mites: Check the undersides and vein areas regularly in warm, dry conditions.
Safety for Alocasia cf. longiloba 'Narrow'
Keep Alocasia cf. longiloba 'Narrow' away from pets and children. Calcium oxalate crystals in the plant can irritate the mouth, tongue and throat if chewed.
Botanical note
The abbreviation “cf.” means “compare with”. Here it marks comparison with Alocasia longiloba, a species whose epithet refers to long lobes.
