Pothos barberianus – Rare Climbing Aroid and Care Guide
Pothos barberianus Schott is a true Pothos species, distinct from Epipremnum, and one of the rarest aroids in cultivation. Native to lowland and ridge forests, this slender, root-climbing liana can grow up to 7 meters in length, displaying striking heterophyllous foliage that evolves from shingle-leaved juveniles to elongated adult leaves. This species thrives in humid, shaded environments and is a fascinating addition to any serious aroid collection.
Why Grow Pothos barberianus?

 
True Pothos species: A rare and scientifically significant climbing aroid.
 
Unique leaf transition: Starts with shingling juvenile leaves before maturing into ovate to lanceolate adult leaves.
 
Epiphytic and terrestrial versatility: Grows as a hemiepiphyte in nature, adapting to various substrates.
Key Growth Insights

 
Native Habitat: Found in primary and disturbed lowland forests, often on clay soils or ridges.
 
Size and Growth: Can reach up to 7 meters, developing a strong climbing habit.
 
Growth Habit: Root-climbing liana with shingling juvenile leaves and elongated adult foliage.
 
Toxicity: Contains calcium oxalate crystals, making it toxic if ingested.
How to Care for Pothos barberianus

 
Best Placement: Prefers a humid, shaded environment with a vertical support structure.
 
Light Requirements: Thrives in bright, indirect light but adapts to lower light conditions.
 
Watering Routine: Keep soil slightly moist but avoid waterlogging; allow the top layer to dry slightly.
 
Humidity Needs: Requires high humidity (above 70%) for optimal growth.
 
Ideal Temperature: Prefers temperatures between 20°C-30°C.
 
Soil Mix: Well-draining mix with orchid bark, perlite, and sphagnum moss to mimic natural epiphytic conditions.
 
Repotting Tips: Repot every 2-3 years to refresh soil and provide space for root development.
 
Fertilizing: Use a balanced liquid fertilizer every 6 weeks during the growing season.
 
Propagation: Best propagated through stem cuttings with aerial roots.
 
Hydroponic Suitability: Less suited to hydroponics due to its climbing and epiphytic nature.
 
Pruning Advice: Trim leggy growth to encourage a more structured form.
Common Issues and Solutions

 
Pests: Can attract thrips and mealybugs; treat with neem oil, or use beneficial insects or insecticidal soap.
 
Yellowing Leaves: Usually a sign of overwatering—allow the soil to dry slightly between waterings.
 
Slow Growth: Often caused by insufficient humidity or poor lighting.
Additional Care Insights

Pothos barberianus thrives when provided with a rough-textured climbing surface, such as moss poles or tree bark, to encourage strong root attachment and mature leaf development. In its natural habitat, it grows both terrestrially and epiphytically, making it adaptable to different environments.
What’s Behind the Name?

The genus Pothos belongs to the Araceae family, distinct from Epipremnum. The species name barberianus was first published in 1856, recognizing the botanist who classified it.
