Alocasia nebula 'Silver' ('Black Diamond') has thick rounded leaves with a cool silver-grey surface and darker vein contrast. The blades are firm, slightly textured and held in a compact crown, giving the plant a dense display of grey, green and charcoal tones.
New leaves can shift in colour as they mature, with the clearest pattern in bright, softened indoor light. Grow it warm in a coarse aroid substrate with bark and mineral particles so air remains around the roots after watering. Let the upper layer dry lightly before watering again, then empty any standing water. This Alocasia contains calcium oxalate; keep it safely away from pets and children.

How to read these values
These care values are practical reference points for indoor growing. Use them as a starting point, then adjust for your room, pot size, substrate, temperature and how quickly the plant dries.
For more context, read the full product description or visit our Plant Care Guides.
- Light: level and approximate lux at leaf level.
- Watering: “% dry” is the trigger before watering again; a lower % means the mix stays more evenly moist.
- Potting mix: a quick profile of structure, drainage, moisture retention, base material and particle size.
- Temperature: “Ideal” shows the preferred range; “Avoid below” marks where stress risk increases.
- Humidity: target bands (Normal/Moist/Humid); consistency usually matters most.
- Growth habit: growth form (rosette, trailing, climbing) for placement and training.
- Support: shows whether a stake, pole or trellis is needed, optional or unnecessary.
- Growth speed: fast/average/slow under decent indoor conditions—expectations, not a promise.
- Max size indoors: realistic long-term potential; format differs for climbers vs. trailers.
- Toxicity & safety: irritating or toxic compounds and physical hazards such as spines or bristles.
- Origin & habitat: native region and typical habitat context.
