Begonia maculata
The Begonia maculata, commonly known as the Polka Dot Begonia, is an iconic cane-type begonia native to the rainforests of Brazil. It is beloved for its dramatic, wing-shaped olive green leaves that are punctuated by crisp silver polka dots and feature a striking deep burgundy-red underside. Beyond its spectacular foliage, it is known for producing pendulous clusters of delicate white flowers under the right conditions.

Care Guide
Begonia maculata Care Guide
Light
Thrives in bright, indirect light. Direct sunlight should be avoided as it will scorch the leaves and cause the silver spots to fade. However, too little light will result in leggy growth and a loss of leaf color.
Watering
Keep the soil consistently moist but never soggy. Allow the top inch of soil to dry out before watering again. This plant is sensitive to overwatering, which can lead to root rot.
Humidity
Requires high humidity (ideally above 50%). Use a humidifier or a pebble tray to increase moisture. Avoid misting the leaves directly, as Begonias are susceptible to powdery mildew and fungal spotting.
Temperature
Maintain temperatures between 65°F and 85°F (18°C - 30°C). Keep the plant away from cold drafts and heating vents.
Maintenance
Prune regularly to encourage bushier growth and prevent the canes from becoming too tall and top-heavy. Provide a stake or trellis if the plant begins to lean.
