Polka Dot Begonia

The Begonia maculata — nicknamed polka dot for its signature silver spots — has been one of the trendiest plants in recent years. Its asymmetric angel-wing leaves, dark green spotted with silver above and burgundy red below, create a spectacular contrast. Bonus: it naturally flowers indoors (white clusters).

What you really need to know

Moderately difficult plant: you need to find the right humidity/water balance. Too much water = soft stems, too little = lower-leaf drop. Fast growth in good conditions, needs staking once it reaches 60 cm.

Light

Bright indirect light. No direct sun (burns the fragile leaves). In low light, petioles stretch and the plant gets leggy. Optimum: 1 m from an east- or west-facing window.

Watering

Every 5 to 7 days. Substrate slightly moist at all times without being soaked. Check with a finger 2 cm in — slightly moist = perfect, dry = water.

Humidity and temperature

Ideal 50-70 % humidity. Tolerates dry air better than the Calathea or Maranta, but prefers a humidifier in winter. Temperature 18-24 °C.

Pruning to bushen up

The Begonia maculata grows upward quickly. To keep a balanced plant, pinch tips regularly. Cuttings root easily in water.

Mistakes to avoid

• Wetting leaves: white spots, possible powdery mildew
• Overwatering: soft stems, base rot
• Direct sun: scorched leaves
• Pot too large: prefers being root-bound

Toxicity

⚠️ Mildly toxic to cats and dogs. Symptoms: drooling, vomiting if ingested.

Propagation

Very easy in water: cut a stem with a node, submerge for 2-3 weeks, roots appear quickly. Plant when roots reach 5 cm. Our water propagation guide covers the details.

Flowering

Clusters of small waxy white flowers, often in summer. Cut spent flowers to stimulate new blooms.
