About Flame Vine
A vigorous, evergreen climbing vine that erupts into a spectacular curtain of bright orange tubular flowers during the dry season, covering walls, fences, and rooftops in cascading sheets of fiery color. When in full bloom, the vine is visible from a great distance, transforming entire structures into walls of living flame. Flame Vine belongs to the Bignoniaceae family and originates from Southern Brazil, Paraguay, and Argentina; widely cultivated in tropical regions worldwide..
Flame Vine is a showstopper in Philippine gardens, commonly seen draping over concrete fences, pergolas, and rooftops in subdivisions throughout Metro Manila, Laguna, and Cavite. When it blooms during the dry season (January to April), it creates an unforgettable spectacle visible from the street. It is popular for covering unsightly walls and fences. Filipino gardeners should ensure they provide a very strong support — the vine becomes remarkably heavy over time. Available at most nurseries along Marcos Highway in Antipolo and Quezon Avenue in QC.
Also known as: Orange Trumpet Vine, Golden Shower Vine.
Popular Varieties
- Pyrostegia venusta (standard orange — the most common form)
- Pyrostegia venusta 'Tangerine Beauty' (deeper orange-red)
How to Plant Flame Vine in the Philippines
Flame Vine can be propagated through stem cuttings, air layering. The recommended method is semi-hardwood stem cuttings.
Propagation Steps
- Step 1: Select 20-30 cm stems from mature, non-flowering branches.
- Step 2: Remove lower leaves, leaving 2-3 pairs at the top.
- Step 3: Dip in rooting hormone and plant in moist soil or coco peat.
- Step 4: Keep in partial shade and maintain moisture.
- Step 5: Roots develop in 4-6 weeks.
- Step 6: Transplant to a permanent location near a sturdy support structure (wall, pergola, or strong fence).
Care Guide
Sunlight
Full sun (needs maximum sun exposure for best flowering). Position your flame vine where it receives the right amount of light for healthy growth in Philippine conditions.
Water
Moderate watering, 2-3 times per week during establishment. Drought-tolerant once established. Reducing water slightly during the dry season can trigger heavier flowering. Adjust frequency during the Philippine rainy season when humidity is higher and soil stays moist longer.
Temperature & Humidity
Ideal temperature range: 25-38°C (thrives in Philippine lowland heat). Moderate — tolerates both dry and humid conditions The warm, humid Philippine climate is well-suited for growing flame vine outdoors or indoors.
Fertilizer
High-phosphorus fertilizer (5-10-10) twice a year — at the start and end of the rainy season. Avoid excess nitrogen which promotes leaves over flowers.
Pruning
Prune hard immediately after flowering to control size and stimulate new flowering wood for the following season. Without pruning, the vine can become extremely heavy and damage supports.
Toxicity & Safety
Non-toxic. Safe around children and pets.
Common Problems & Solutions
Vine too heavy for support structure
Cause: Rapid, unchecked growth without pruning
Solution: Prune annually after flowering. Ensure support structure is very sturdy (concrete wall, steel trellis). Avoid lightweight wooden fences.
No flowers
Cause: Too much shade, excess nitrogen, or lack of seasonal water stress
Solution: Ensure full sun. Reduce watering slightly in the dry season to trigger blooming. Stop nitrogen fertilizers.
Vine invading roof or gutter
Cause: Tendrils and aerial roots clinging to structures
Solution: Train and prune regularly. Keep the vine away from roof edges, gutters, and electrical lines.
Scale insects on older stems
Cause: Woody stems sheltering scale colonies
Solution: Scrub off with a brush. Apply horticultural oil to affected areas.
