How to read these metrics
These metrics are standardised reference points. We compile them by reviewing and cross-checking multiple botanical and horticultural references, then refining them through real-world growing experience. Source links: Plant Care Resources.
Please use the values as guidance. Conditions vary by home, so the same plant can respond differently. For plant-specific context, read the full product description and browse our Plant Care Guides.
- Light: level + approximate lux at leaf level; DLI is the daily light “dose” for grow lights.
- Watering: “% dry” is the trigger before watering again; lower % stays more evenly moist.
- Potting mix: one-line profile (structure/drainage • moisture buffer • base • particle size).
- Temperature: “Ideal” comfort range; “Avoid below” marks higher stress risk.
- Humidity: target bands (Normal/Moist/Humid); consistency usually matters most.
- Growth habit: growth form (rosette, trailing, climbing) for placement and training.
- Support: needed/optional/none — whether stake, pole, or trellis improves structure and size.
- 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: chemical irritants/toxicity and physical hazards (spines, bristles).

Begonia rex 'Black Mambo' – Dramatic Foliage With Velvet Texture
Begonia rex 'Black Mambo' brings serious drama to any indoor plant collection with its dark, velvety leaves and swirling patterns. Deep ebony tones, subtle red undertones, and cream-colored stems create a striking contrast that catches the light beautifully.

- Size: Reaches about 30 – 40 cm tall and wide indoors

Origins and Growth Traits
Begonia rex cultivars originate from hybrid breeding programs based on tropical Begonia species from regions like Assam, northern India, and southern China. 'Black Mambo' was selected specifically for its deep coloration and compact form. Indoors, it stays around 30 – 40 cm tall with a spreading, bushy growth pattern when given ideal conditions.

- Humidity: Prefers humidity above 50%. Use humidifiers or group with other plants.
- Temperature: Best kept between 18 – 24 °C. Protect from sudden cold drafts.
