Begonia polygonoides is to the tropical forests of West Africa, where it typically grows as an epiphytic shrub on tree trunks. Known for its thick, almost succulent leaves that shift between green and red, this Begonia is slow-growing and can adapt well to indoor conditions given the right care. It is best suited to hanging baskets or terrariums, as its trailing growth habit and humidity needs make it ideal for displays with higher moisture levels and indirect light.

Native to

This species is originally from regions in Africa, specifically countries like Cameroon and Gabon, where it thrives in moist, shaded environments within forest canopies. Its adaptation to these humid, lower-light conditions makes it relatively easy to care for indoors, especially if provided with similar humidity and light.

Water

Water this Begonia sparingly, as its semi-succulent nature allows it to tolerate slight dryness in the top layer of soil. Water only when the top inch of soil feels dry, approximately every 1–2 weeks depending on ambient humidity. A well-draining soil mix with perlite or coarse sand will help prevent root rot, a common issue if overwatered.

Light

Bright but indirect light is ideal for Begonia polygonoides. Direct sunlight should be avoided, as it can scorch the leaves. Positioning it near a north or east-facing window works well, and it also adapts to artificial grow lights if natural light is limited.

Humidity

Humidity around 50–70% is optimal for this Begonia, which thrives in moist air. It’s a good candidate for terrariums or grouped plant displays to maintain these levels. A pebble tray or humidifier can also help, as misting directly can encourage mildew on its leaves.

Temperature

Ideal temperatures for Begonia polygonoides are between 18–27°C. It’s sensitive to sudden temperature changes, so keeping it away from draughts and cold windows in winter is essential to its health.
