Begonia burkillii 'Silver Edge' – Rare Indian Rhizomatous Begonia with Contrasting Foliage


Begonia burkillii 'Silver Edge' is a refined cultivar of a rhizomatous Begonia species native to northern India. Its foliage is instantly recognisable: broad blades with silver-green fields framed by almost black edging, while mint-green veins cut across the surface like fine tracery. Compact and elegant, this Begonia offers an unusual colour balance that sets it apart from the more flamboyant Rex types.
 
● Visual Qualities of Begonia 'Silver Edge'


Leaf tones: Silver-green patches bordered by near-black margins
Venation: Mint-green veins provide striking contrast
Habit: Rhizomatous growth forming low, compact clumps
Size range: Indoors, usually 20 – 30 cm tall and wide
 
● Where It Comes From


The wild species Begonia burkillii grows in humid forest understories of northern India, where it thrives in shaded conditions with consistent moisture. The cultivar ‘Silver Edge’ was selected for its particularly sharp contrast of silver, green, and black, offering foliage appeal distinct from other rhizomatous Begonias.
 
● Daily Care Essentials


Light: Bright, indirect light maintains strong colour contrasts; avoid harsh sun
Water: Keep soil evenly moist; allow the top layer to dry slightly before watering again
Humidity: Stable 60%+ humidity prevents crisping of the edges
Temperature: Prefers 18 – 26 °C; protect from draughts and sudden chills
Soil: Airy, organic-rich mix with good drainage
Fertiliser: Diluted balanced feed every 3 – 4 weeks in active growth
 
● Seasonal Behaviour Indoors


'Silver Edge' holds its foliage year-round when kept in stable conditions. Growth is strongest in spring and summer as rhizomes push out new leaves. During cooler months, development slows but does not fully stop, making it a reliable ornamental even in winter.
 
● Typical Troubles and Fixes


Brown rims: Low humidity or erratic watering; stabilise moisture and raise humidity
Duller colours: Too little light; move to a brighter filtered position
Pests: Occasionally susceptible to mealybugs and spider mites; inspect regularly
 
● Grower Questions


How big will it get? Indoors it usually remains compact, 20 – 30 cm tall and wide.
How to propagate? By rhizome cuttings or leaf sections under high humidity conditions.
Is it pet safe? No, like all Begonias it contains oxalates and should be kept out of reach of pets and children.
 
● Name Origins


The genus Begonia was named in the 18th century by Charles Plumier in honour of Michel Bégon (1638 – 1710). The species epithet burkillii honours Isaac Henry Burkill, a British botanist who worked extensively on Indian flora. 'Silver Edge' extends this heritage as a modern cultivar with distinctive ornamental contrasts.
