About Rangoon Creeper
A vigorous, semi-woody climbing vine famous for its clusters of tubular flowers that change color as they age — opening white, turning pink, and deepening to red, so that a single cluster displays all three colors simultaneously. This color-changing trick, combined with a sweet fragrance that intensifies at night, makes the Rangoon Creeper one of the most enchanting tropical vines in existence. Rangoon Creeper belongs to the Combretaceae family and originates from Tropical Asia (India, Myanmar, Philippines, Malaysia); native to and widespread across the Philippines..
Niyog-niyogan is one of the most culturally significant plants in Filipino herbal medicine and gardening. It is important to note that the ornamental Rangoon Creeper (Combretum indicum) and the medicinal 'niyog-niyogan' are the SAME plant — the species was formerly classified as Quisqualis indica before being reclassified to Combretum indicum by taxonomists. Filipino herbalists have long used the seeds as a traditional deworming remedy (anthelmintic), particularly for children — the roasted seeds were given to expel intestinal parasites. However, the raw seeds can be toxic and should only be used under traditional healer guidance. Beyond its medicinal fame, the vine is widely grown for its stunning multi-colored flower clusters and sweet evening fragrance. It is a common sight on Filipino fences, gates, and arbors, especially in provincial homes. The vine is extremely easy to grow, readily available, and often shared as cuttings among neighbors.
Also known as: Chinese Honeysuckle, Drunken Sailor.
Popular Varieties

How to Plant Rangoon Creeper in the Philippines
Rangoon Creeper can be propagated through seeds, stem cuttings, root suckers. The recommended method is semi-hardwood stem cuttings or root suckers.
Propagation Steps
- Step 1: Take 20-30 cm semi-hardwood cuttings from healthy vines.
- Step 2: Remove lower leaves and dip in rooting hormone.
- Step 3: Plant in moist garden soil near a fence, arbor, or trellis.
- Step 4: Keep moist and shaded for the first few weeks.
- Step 5: Roots establish in 4-6 weeks. Alternatively, dig up root suckers with attached roots for instant transplanting.

Care Guide
Sunlight
Full sun to partial shade (flowers best in full sun). Position your rangoon creeper where it receives the right amount of light for healthy growth in Philippine conditions.
Water
Water regularly during establishment. Once established, moderately drought-tolerant. Water deeply once or twice per week during the dry season. 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 to high — perfectly suited to Philippine conditions The warm, humid Philippine climate is well-suited for growing rangoon creeper outdoors or indoors.
Fertilizer
Balanced fertilizer (14-14-14) every 4-6 weeks during the growing season. Bloom booster (10-30-20) encourages heavier flowering.
Pruning
Prune hard after the main blooming cycle to control size and shape. Without pruning, the vine can overwhelm its support structure and neighboring plants.
Toxicity & Safety
Seeds are toxic if consumed raw in large quantities — they have been used medicinally as a dewormer but can cause hiccups, nausea, and diarrhea in excess. The flowers and foliage are not toxic. Exercise caution around children.
Common Problems & Solutions
Vine becoming too aggressive and smothering other plants
Cause: Vigorous natural growth habit and root suckering
Solution: Prune regularly and aggressively. Remove root suckers that appear away from the main plant. Contain roots if necessary.
Fewer flowers, mostly leaves
Cause: Too much shade or nitrogen
Solution: Ensure full sun. Switch to a high-phosphorus fertilizer.
Caterpillars on leaves
Cause: Various moth and butterfly larvae
Solution: Hand-pick or apply Bt spray. Minor defoliation is tolerable — the vine recovers quickly.
Sticky honeydew on leaves
Cause: Aphids or scale insects
Solution: Spray with neem oil or insecticidal soap. Prune out heavily infested sections.
