Key Characteristics



 
Foliage: Trilobed leaves with long, narrow lobes; mature leaves can grow up to 18 inches in length.
 
Growth Habit: Vigorous climber; benefits from support structures to encourage vertical growth.
 
Origin: Native to South America.


Ideal Growing Conditions



 
Light: Thrives in medium, indirect light; avoid direct sunlight to prevent leaf burn.
 
Humidity: Prefers high humidity environments; regular misting or use of a humidifier is beneficial.
 
Soil: Requires a well-draining, rich organic mix; avoid wet, mucky, or dry, sandy soils.


Care and Maintenance



 
Watering: Keep soil moist but not waterlogged; allow the top inch of soil to dry out between waterings.
 
Fertilization: Fertilize sparingly, at least 6 inches away from the base, tri-annually with a slow time-released product to support growth.
 
Support: Provide a mossy post or burlap-wrapped pole to climb, promoting healthy vertical growth.


Propagation


Propagation is typically achieved through stem cuttings. Cut a healthy stem with at least one node and place it in water or moist soil until roots develop. Once rooted, transplant into a suitable potting mix and provide appropriate support for climbing.


Common Issues and Solutions



 
Yellowing Leaves: May indicate overwatering; ensure soil is well-draining and adjust watering frequency.
