Begonia amphioxus

It’s not the exact plant in the photo that you’re buying but they’re all beautiful!
Begonia amphioxus is one of the most visually distinctive species in the Begonia genus. It is characterized by:

• Narrow, lance-shaped leaves
• Bright red spots scattered across the leaf surface
• Red or pink leaf margins
• A thin, semi-translucent leaf texture

The plant grows in a somewhat upright but delicate, bushy form and typically reaches 20–40 cm in height. It is considered a sensitive but highly decorative collector’s plant.

History and Origin

• Discovered in the 1980s
• Described scientifically by botanist Ruth Kiew in 1996
• Native to limestone forests in Sabah, Borneo
• Grows naturally in warm, humid, shaded environments, often in limestone crevices

Its natural habitat explains why it prefers good airflow, high humidity, and dislikes waterlogged soil.

Care Tips

Light

• Prefers bright, indirect light
• Too little light leads to pale leaves and weak growth
• Too much direct sun causes leaf burn and loss of color intensity

Watering

• Maintain lightly moist soil without keeping it soaked
• Allow the top layer of soil to dry slightly between waterings
• Soft, filtered or rainwater is recommended

Humidity

• Ideal humidity is 70–90 percent
• Thrives in terrariums, display cases or controlled environments
• Low humidity causes crispy edges and slowed growth

Temperature

• Ideal temperature range: 20–28°C (68–82°F)
• Avoid temperatures below 17°C (62°F)

Soil

• Use a very airy, fast-draining substrate
• A suitable mix can include: coco or peat, perlite, bark, and a small amount of crushed limestone
• Avoid dense soils that retain too much moisture

Fertilization

• Feed lightly every 2–3 weeks during the growing season
• Use a diluted, balanced fertilizer

Additional Notes

• Sensitive to overwatering and sudden environmental shifts
• Performs best with stable humidity and temperature
• Propagation from stem cuttings is possible but requires high humidity to root well
