Begonia masoniana, universally known as the "Iron Cross Begonia," is one of the most recognizable and beloved foliage begonias in cultivation. Native to southern China and northern Vietnam, this rhizomatous species features large, asymmetrical, heavily textured bright green leaves adorned with a distinctive dark chocolate-brown pattern at their center – a bold marking that unmistakably resembles the Iron Cross used on medieval shields during the Crusades.
The species name honors L. Maurice Mason, the English plant collector who brought this remarkable plant from Singapore to England in 1952 and gave it its evocative common name. The leaves have a rough, puckered texture covered with fine reddish hairs, creating a tactile quality that invites touch. While the plant does produce small pinkish-white flowers in erect panicles, the magnificent foliage remains the undisputed star attraction. This begonia has earned the Royal Horticultural Society's Award of Garden Merit for its outstanding ornamental qualities.

Yes, Begonia masoniana is toxic to cats, dogs, and horses according to the ASPCA. The plant contains soluble calcium oxalates, with the underground rhizomes being the most toxic part. If ingested, pets may experience vomiting, excessive drooling, oral irritation, and difficulty swallowing. While rarely fatal, the symptoms are uncomfortable. Keep this plant out of reach of pets, and contact your veterinarian immediately if you suspect ingestion.
The name comes from the distinctive dark chocolate-brown pattern at the center of each leaf, which strikingly resembles the Iron Cross – a symbol used on shields and flags during the medieval Crusades. English plant collector L. Maurice Mason gave the plant this evocative common name when he brought it from Singapore to England in 1952. The species name "masoniana" also honors him. The bold cross-shaped marking makes this one of the most instantly recognizable houseplants in the world.
White powdery patches on Begonia masoniana indicate powdery mildew, a fungal infection that thrives when foliage stays wet in humid conditions with poor air circulation. Never mist this plant directly – the textured, hairy leaves trap moisture and are highly susceptible to mildew. Instead, increase humidity using a pebble tray or humidifier. Remove affected leaves promptly, improve air circulation around the plant, and ensure water only reaches the soil, not the foliage. Severe cases may require fungicide treatment.
Water when the top 2-3 cm of soil feels dry – typically weekly during active growth, less frequently in winter. The underground rhizomes store water, making overwatering more dangerous than slight underwatering. Always water at the base of the plant, never on the leaves, to prevent mildew. Ensure excellent drainage and never let the plant sit in water. In winter when growth slows, reduce watering significantly but don't allow complete dryness. Yellow, drooping leaves typically indicate overwatering; crispy brown edges suggest underwatering or low humidity.
Fading of the distinctive chocolate-brown cross pattern usually indicates too much direct light. While Begonia masoniana needs bright light for healthy growth, direct sunlight bleaches the markings and can burn the leaves. Move the plant to a spot with bright but filtered or indirect light – near a window with sheer curtains, or a few feet back from south-facing windows. The vibrant contrast between the bright green leaves and dark cross pattern will return once lighting conditions are corrected.
