Begonia x ricinifolia ‘Immense’ – oversized textured foliage with a bold tropical presence

Begonia x ricinifolia ‘Immense’ is a striking rhizomatous hybrid known for its massive palmate leaves and crinkled texture.

This cultivar stays low to the ground but spreads wide, making it a sculptural statement plant for tabletops, low stands, or underplanting larger species. It’s an easy-care showpiece that thrives in bright shade and consistent warmth.

Begonia ‘Immense’ care tips
 
Light: Bright indirect light or dappled shade — no direct sun
 
Water: Keep soil evenly moist but not soggy; allow top 2 cm to dry slightly between watering
 
Humidity: Thrives in 50–70%; avoid dry air and drafts
 
Temperature: 18–26 °C is optimal; protect from cold snaps and heat stress
 
Soil: Rich, airy mix with compost, bark, and perlite for drainage
 
Repotting: Every 1–2 years as rhizomes spread horizontally
 
Feeding: Balanced liquid fertilizer every 4–6 weeks during growth phase
 
Propagation: Rhizome division or leaf cuttings with petiole attached
 
Hydroponics: Not suitable — prefers organic substrate with airflow
 
Pruning: Trim off older or damaged leaves close to rhizome
Common issues and fixes
 
Leaf edges browning: Often due to dry air — raise humidity or move away from airflow
 
Wilting or limp leaves: Usually underwatering or root-bound conditions
 
Fungal spotting: Caused by overhead watering or poor air circulation — water at base and allow airflow
 
Mealybugs: Can settle on leaf bases — treat early with insecticidal soap or neem oil
 
Yellowing leaves: Linked to overwatering — allow surface to dry between waterings
Extra notes and styling
'Immense' makes a dramatic display in wide ceramic planters or shallow bowls where its full leaf span can develop. Best shown off solo or with smaller, fine-textured plants that contrast its boldness. Avoid crowding it into narrow shelves — give this one space to spread and show off its shape. It's also excellent for humid rooms or grouped with moisture-loving aroids and ferns.

“Begonia” was named after Michel Bégon, a French patron of botany. The hybrid group “ricinifolia” refers to leaves shaped like those of the castor bean plant (Ricinus). The cultivar name ‘Immense’ directly references its exaggerated foliage scale and wide-spreading growth pattern.
