Hoya crassipetiolata (Long Leaf Form) – Elegant Epiphyte with Extended Foliage

Hoya crassipetiolata Aver., V.T. Pham and T.A. Le (2017), native to Vietnam, is known for its thick petioles and elongated, leathery leaves. This long-leaf form is a phenotypic variant found in cultivation, typically displaying leaves up to 12 cm in length and 2 – 4 cm wide. The plant thrives in bright, indirect light and offers a clean, architectural aesthetic when allowed to trail or climb. When mature, it may produce small, fragrant flowers, adding further charm to this adaptable epiphytic species.
Why Choose the Long Leaf Form?
 
Leaf Morphology: Tapered, pointed leaves up to 12 cm long and 2 – 4 cm wide with subtle venation and a semi-glossy surface.
 
Growth Habit: Climbing or trailing vines with thick petioles and strong internodal spacing.
 
Blooms: Pale cream to soft pink, ~1 – 1.5 cm across, mildly fragrant. Flowers form on persistent peduncles — never remove spent stalks.
 
Indoor Suitability: Ideal for moss poles, open shelving, or cascading displays in moderate to bright rooms.
Care Guide for Hoya crassipetiolata (Long Leaf Form)
 
Light: Bright, indirect light encourages healthy leaf growth. Avoid harsh midday sun.
 
Watering: Water when the top 2 – 3 cm of substrate is dry. Ensure excellent drainage to prevent rot.
 
Humidity: Prefers 60 – 80%, but adapts well to standard indoor levels with airflow.
 
Temperature: Best between 18 – 28 °C. Avoid prolonged exposure to temperatures below 15 °C.
 
Substrate: Use a mix of orchid bark, perlite, and a small amount of coco coir or potting soil for structure and drainage.
 
Feeding: Apply a balanced liquid fertilizer every 4 – 6 weeks during active growth, diluted to half strength.
 
Growth Rate: Moderate to fast under optimal conditions. Expect 10 – 20 cm of new vine growth per season.
Where to Place Hoya crassipetiolata (Long Leaf Form)
This Hoya is perfect for trailing from a wall-mounted planter, winding around a trellis, or cascading from a high shelf. Its long, pointed foliage creates a clean, sculptural silhouette — especially striking in modern or minimal interiors.
Common Issues and Fixes
 
Yellowing Leaves: Usually due to overwatering or insufficient light. Adjust watering and move to a brighter spot.
 
Pests: May attract spider mites or mealybugs. Inspect regularly and treat with insecticidal soap or neem oil if needed.
 
No Flowers: Provide steady care, good light, and do not remove old flower stalks — reblooming occurs from mature peduncles.
Extra Tips for Success
 
Propagation: Take stem cuttings with 1 – 2 nodes. Root in water or moss under warm, humid conditions.
 
Cleaning: Wipe leaves with a damp cloth or use soft microfiber gloves to remove dust and improve photosynthesis.
 
Training: Guide vines onto a moss pole, hoop, or netting for vertical impact and support.
Is Hoya crassipetiolata Pet-Safe?
Not officially listed as toxic, but ingestion may cause irritation. Best kept away from pets and children as a precaution.
Etymology and Botanical Notes
The genus Hoya honors British botanist Thomas Hoy. The species epithet “crassipetiolata” means “thick-petioled,” referring to the robust leaf stalks characteristic of the plant. First described in 2017, this species remains a favorite among collectors for its elegant structure and reliable growth.
