Common Name(s)
Rex Begonia, Painted-leaf Begonia, Cathedral Begonia
Origin
Cultivar developed from Begonia rex hybrids, originally native to northeast India.
Light
Prefers bright, indirect light. Avoid prolonged direct sunlight, which can scorch the leaves and fade their beautiful colouring. An east or north-facing window is ideal.
Water
Water when the top 2–3cm of compost feels dry. Keep the soil lightly moist but never waterlogged. Reduce watering during winter and avoid leaving water sitting in the centre of the plant.
Humidity
Enjoys moderate to high humidity. Rather than misting, increase humidity with a pebble tray, humidifier or by grouping plants together.
Soil
Thrives in a light, free-draining compost. A quality houseplant compost mixed with perlite and a small amount of fine orchid bark provides excellent drainage while retaining enough moisture. Repot every 1–2 years during spring.
Food
Feed every 4–6 weeks throughout spring and summer using a balanced liquid houseplant fertiliser at half strength. Pause feeding during autumn and winter.
Temp
Prefers temperatures between 18–24°C. Avoid temperatures below 15°C, cold draughts and sudden temperature changes.
Pet-safe
No. Toxic if ingested, so keep out of reach of cats, dogs and other pets.
Sprouts Top Tips
Rotate your plant every few weeks to encourage even growth and maintain its symmetrical shape. Remove any damaged or ageing leaves to keep the plant looking its best, and avoid overwatering, as Begonias are more tolerant of slightly dry compost than consistently wet roots.
Extras
Begonia ‘Cathedral’ can be propagated from leaf cuttings. Even a single healthy leaf with a section of vein attached can develop into a new plant with a little patience.
