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 reginula ‘Ninja’
Ninja is a compact reginula form often sold as ‘Black Ninja’, with dark, thick leaves and a more embossed surface than standard Black Velvet forms. Leaves are matte and deeply coloured, with pale veins creating strong contrast.
The plant grows from a short base and keeps a tight, upright form. Some leaves show a subtle double vein near the margin.
Alocasia reginula is linked to Borneo and grows as a compact tropical aroid.
Older plants may flower, producing a small spathe and spadix.
The species name reginula means “little queen”, which fits the compact scale of this dark-leaved Alocasia.
Practical care
- Bright, indirect light.
- Stable warmth between 18–29 °C.
- Around 60–80% humidity with airflow.
- Allow partial drying between waterings.
- Use a fine, well-draining mix.
- Feed lightly during active growth.
Warm roots, filtered light and careful watering matter most.
Troubleshooting
- Dull leaf surface: rubbing, hard wiping or leaf-shine residue.
- Soft base: excess moisture or cold conditions.
- Drooping leaves: check pot weight and roots.
- Crisp edges: dry air or heat.
- Small new leaves: increase usable light and keep the pot warmer.
Leaf handling
Keep leaves clean with a soft brush or gentle rinse, then let them dry with airflow. Keep this plant out of reach of pets and children; Alocasia tissue can irritate the mouth and throat if ingested.
