Begonia masoniana 'Iron Cross' at a glance:
Begonia masoniana 'Iron Cross' is recognised immediately by its puckered pale green leaves stamped with a dark central cross, a pattern made even stronger by fine hairs and a slightly glossy surface. It grows from rhizomes into compact clumps, so the foliage sits low and concentrated rather than being spread along long canes or climbing stems.
Bright shade and high humidity keep the surface healthy, while an airy organic substrate allows steady moisture without turning the rhizomes soft. Let only the upper layer dry slightly between waterings, avoid direct sun and cold drafts, and remove old leaves before they collapse across the crown. Small greenish-white flowers can appear, but the plant is grown for leaf pattern and texture first. Few begonias are as instantly identifiable, which is why this cultivar remains a classic even among much newer foliage introductions.

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;
- 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).
- Origin & habitat: native region + typical biome/habitat as context.
