Begonia masoniana 'Tricolor' – Variegated Iron Cross Begonia with Cream, Green, and Brown Patterns


Begonia masoniana 'Tricolor' is a rare and highly decorative cultivar of the Chinese species Begonia masoniana. First raised by breeder Mike Kartuz from seed, this selection stood out among its siblings for its striking variegation. Its broad, textured leaves are marked by the iconic brown “iron cross” in the center, surrounded by green, and framed by a creamy outer band that extends towards the margins. This bold tricolour effect makes it a must-have for collectors of unusual foliage Begonias.
 
● Why Begonia 'Tricolor' Stands Out


Leaf pattern: Central brown iron cross set against green and cream zones
Colour play: Unique tricolour palette not found in standard forms
Leaf texture: Heavily puckered blades add depth and tactile appeal
Size indoors: Generally 20 – 30 cm tall and wide
 
● Botanical Background


Begonia masoniana is native to southern China and northern Vietnam, where it grows in shaded, humid forest environments. The wild type is best known for its dark iron cross marking, but the 'Tricolor' cultivar elevates this pattern with creamy variegation. It was developed by U.S. breeder Mike Kartuz, whose seed-raised plants revealed this distinct, ornamental form.
 
● Care Guide for Begonia masoniana 'Tricolor'


Light: Bright, indirect light enhances its variegation; avoid harsh sun
Watering: Keep soil evenly moist but allow the surface to dry slightly before rewatering
Humidity: Thrives at 60%+; stable humidity preserves leaf edges
Temperature: Prefers 18 – 26 °C; sensitive to cold drafts
Soil: Airy, well-draining potting mix with organic matter
Feeding: Apply diluted fertilizer every 3 – 4 weeks during active growth
 
● Growth and Seasonal Notes


'Tricolor' is evergreen indoors and produces new leaves steadily from its rhizomatous base. The puckered surface, iron cross marking, and creamy margins stay consistent through the seasons if grown with stable light, moisture, and humidity.
 
● Potential Issues and Solutions


Brown tips: Caused by low humidity or irregular watering
Faded iron cross: Linked to insufficient light; move to a brighter filtered spot
Pests: May attract mealybugs or spider mites; treat promptly if detected
 
● Questions About Begonia 'Tricolor'


How big does it get? Indoors, it stays compact at 20 – 30 cm tall and wide.
Can it be propagated? Yes, by rhizome divisions or leaf cuttings under high humidity.
Is it safe for pets? No, like all Begonias it contains oxalates and should be kept away from pets and children.
 
● Etymology of Begonia


The genus Begonia was named in the 18th century by botanist Charles Plumier in honour of Michel Bégon (1638 – 1710), a French administrator and amateur botanist who supported early plant exploration. 'Tricolor' extends this heritage as one of the most striking modern cultivars of the Iron Cross Begonia.
