Peacock Begonia
Begonia pavonina
flowerBegonia pavonina is a stunning ornamental foliage plant native to Borneo, prized for its dramatic, iridescent blue-green leaves with deep burgundy undersides and silvery veining that resembles peacock feathers. This tender perennial is grown primarily as a houseplant or in humid greenhouse environments and produces delicate pink flowers, though foliage is the main attraction. It is considered one of the most visually striking begonias but requires precise humidity and care conditions.

Propagation & Establishment
4-6 weeksTiny plantlets from leaf or stem cuttings develop roots and first true leaves
Maintain 70-80°F, 80%+ humidity; use well-draining propagation mix; mist frequently; provide gentle light without direct sun
Young Plant Development
6-8 weeksPlant establishes root system and produces 4-6 leaves; new growth is vibrant but not yet at full intensity
Keep humidity high (60-80%); water carefully to avoid fungal issues; apply diluted balanced fertilizer monthly; do not overwater
Mature Foliage
Ongoing (several months to years)Plant reaches full size with multiple stems; leaves display characteristic iridescent blue-green with deep burgundy backs and striking silvery patterns
Maintain strict humidity levels; bright indirect light to preserve coloration; monthly balanced fertilizer during growing season; prune to promote bushiness and shape
Flowering
4-6 weeks intermittentlyDelicate pale pink flowers appear in loose clusters above foliage in spring/summer; flowers are secondary to leaf display
Provide consistent warmth (68-75°F); maintain humidity; deadhead spent flowers to redirect energy if desired; flowers attract occasional interest but remove if taking plant energy
Rest Period
2-3 monthsGrowth slows in winter; plant maintains foliage but produces fewer new leaves
Reduce fertilizer frequency; maintain humidity despite lower evaporation; water less frequently but do not let soil dry out; keep temperature above 60°F

Common Pests
-
Inspect regularly; remove with rubbing alcohol on cotton swab; spray with neem oil or insecticidal soap; isolate infested plant
-
Increase humidity; mist foliage regularly; spray with water to dislodge; use neem oil if severe; ensure good air circulation
-
Allow soil surface to dry slightly between waterings; use sticky traps; apply sand layer on soil; use Bti (Bacillus thuringiensis israelensis) if needed
-
Remove manually with brush or cloth; treat with horticultural oil; apply neem oil; repeat applications necessary
-
Prevent with well-draining soil and careful watering; improve drainage and air circulation; reduce watering frequency; repot in fresh soil if caught early

WildlifePink flowers attract bees, butterflies, and other pollinators indoors and in greenhouses, providing a nectar source in controlled environments where native flowers may not be available. [source]
Harvest Tips
Not a harvest plant; grown for ornamental foliage. Leaves maintain their beauty indefinitely with proper care. Remove dead, yellowed, or damaged leaves by cutting at the petiole to encourage new growth and maintain plant appearance.
Fun Facts
- 🌱 Begonia pavonina's iridescent blue-green color is not caused by pigment but by the microscopic structure of leaf cells (structural coloration), similar to the coloring of peacock feathers—hence its common name.
- 🌱 This species is endemic to the rainforests of Borneo and was nearly extinct in the wild before cultivation by enthusiasts helped preserve it; it remains one of the most expensive and sought-after begonias in the horticultural trade.
- 🌱 The plant's dramatic leaf coloration intensifies under perfect conditions; the same plant grown in inadequate light will display dull green leaves, making proper care essential to reveal its full beauty.
