Commonly known as: Polka Dot Begonia / Angel Wing Begonia
Botanical name: Begonia maculata
The Begonia Polka Dot (Begonia maculata) is one of those plants that looks dramatic without trying too hard. Its elongated, wing-shaped leaves are dotted with silver spots on top, while the undersides glow a deep burgundy red. As it matures, the plant develops tall, cane-like stems that give it a graceful, upright form.
Despite its bold appearance, this Begonia is fairly straightforward to grow once you understand its preferences. It enjoys bright, indirect light, evenly moist soil, and good airflow around the leaves. Unlike many begonias, it prefers not to be constantly wet and responds far better to a consistent watering rhythm.
This plant also benefits from light pruning, which helps keep it bushy and encourages fresh growth. With the right balance of light, water, and airflow, the Polka Dot Begonia becomes a long-lived indoor plant that adds texture and movement to your space.
Begonia Polka Dot Care Guide
Watering – How often should I water it?
Water when the top 2–3 cm of soil feels dry. The soil should stay lightly moist but never soggy. Overwatering is the fastest way to cause stem rot, while letting it dry out completely can lead to leaf drop.
Light – What light does a Polka Dot Begonia need?
Bright, indirect light is ideal. Morning sun is usually fine, but harsh afternoon sun can scorch the leaves. Too little light causes leggy growth and faded spotting
Humidity – Does it need high humidity?
Moderate humidity works best. While it enjoys slightly humid air, avoid misting the leaves directly as this can encourage fungal issues. Good airflow is more important than very high humidity.
Use a light, free-draining mix that holds some moisture without becoming dense. We recommend our Aroid Mix or a DIY blend of
Barks Unlimited Potting Soil with Perlite and a small amount of Bark Chips.
Feeding – How should I fertilise it?
Feed every 4–6 weeks during spring and summer using our
Organic Fertiliser. For a longer-lasting option, add a light dose of Controlled Release Fertiliser at the start of the growing season.
Repotting – When should I repot?
Repot every 12–18 months, or when roots begin to crowd the pot. Move up only one pot size at a time. Begonias prefer being slightly snug rather than over-potted.
Pests – What should I watch for?
Keep an eye out for spider mites, mealybugs, and aphids. Inspect leaf undersides regularly. If pests appear, treat promptly with an insecticidal spray and improve airflow.
Temperature – What temperature suits it best?
Ideal range is 18–26 °C. Protect from cold drafts, heaters, and sudden temperature changes. Growth slows noticeably in cooler conditions.
FAQ’s

Yes, in bright shade and warm weather, but protect it from direct sun and cold.
Q: Why are the leaves dropping?
Usually due to inconsistent watering or sudden temperature changes.
Q: Can I prune it?
Absolutely. Pruning encourages bushier growth and prevents it becoming too leggy.
Q: Is it pet-safe?
