Begonia maculata
Begonia maculata
The Begonia maculata, commonly known as the Polka Dot Begonia, is a popular cane-type begonia native to the rainforests of Brazil. It is beloved for its bold, wing-shaped olive green leaves that are punctuated by crisp silver polka dots and feature a striking deep burgundy-red underside. Give it bright, indirect light, higher humidity, and a planter that lets excess water drain freely.

Full guide →Light
Give it 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.
Water
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 and Temperature
Aim for 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.
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.
Soil and Planter
Use a well-draining, airy potting mix containing peat moss, perlite, and a bit of compost. Choose a planter with drainage holes so excess water can escape.
Common Issues
Brown edges often point to dry soil or low humidity. Yellowing can follow waterlogged soil, so check moisture and drainage before watering again.
