About African Tulip Tree
A fast-growing tropical tree crowned with clusters of large, tulip-shaped, orange-red flowers that bloom almost year-round. The buds hold water and are famously squeezed by Filipino children as natural water pistols. Its broad canopy and vivid blooms make it a striking street and park tree across the Philippine lowlands. African Tulip Tree belongs to the Bignoniaceae family and originates from Tropical West Africa; widely naturalized throughout the tropics including the Philippines..
The African Tulip Tree is one of the most recognizable flowering trees in Philippine cities, lining many streets in Quezon City, Cebu, and Davao. Filipino children know it as the 'water gun tree' because the unopened flower buds are filled with water that squirts when squeezed. While beautiful, it is considered an invasive species by the IUCN and should not be planted near natural forests or protected areas. Commonly available from DENR nurseries and landscape suppliers. Best suited for parks, wide boulevards, and large open lots.
Also known as: Flame of the Forest, Fountain Tree.
Popular Varieties
- Spathodea campanulata (standard orange-red flowers)
- Spathodea campanulata var. aurea (rare yellow-flowered form)
- Spathodea campanulata 'Nana' (dwarf cultivar, rarely available)
How to Plant African Tulip Tree in the Philippines
African Tulip Tree can be propagated through seeds, stem cuttings, root suckers. The recommended method is seeds (prolific and easy to germinate).
Propagation Steps
- Step 1: Collect winged seeds from mature brown pods when they split open naturally.
- Step 2: Sow seeds on the surface of moist, well-draining potting mix — they need light to germinate.
- Step 3: Keep moist and in partial shade. Germination occurs in 7-14 days.
- Step 4: Transplant seedlings when 15-20 cm tall into larger containers or directly into the ground.
- Step 5: Choose a spacious, sunny permanent site away from structures — this tree grows very fast and very large.
Care Guide
Sunlight
Full sun (requires open, unshaded area for best flowering and canopy shape). Position your african tulip tree where it receives the right amount of light for healthy growth in Philippine conditions.
Water
Water regularly when young. Once established (1-2 years), tolerates moderate drought. Deep water during extended dry spells. Adjust frequency during the Philippine rainy season when humidity is higher and soil stays moist longer.
Temperature & Humidity
Ideal temperature range: 24-35°C (thrives in Philippine lowland heat year-round). Moderate to high — well-suited to the Philippine climate The warm, humid Philippine climate is well-suited for growing african tulip tree outdoors or indoors.
Fertilizer
Complete fertilizer (14-14-14) twice a year during wet season. Mature trees rarely need supplemental feeding.
Pruning
Prune young trees to develop a strong central leader. Remove low-hanging branches for clearance. Mature trees need minimal pruning — remove dead wood after typhoon season.
Toxicity & Safety
Flowers, seeds, and bark contain compounds that may be mildly toxic if ingested. The water inside flower buds is harmless in small quantities.
Common Problems & Solutions
Invasive spreading
Cause: Produces thousands of wind-dispersed seeds; can colonize disturbed areas rapidly
Solution: Remove seed pods before they open if near natural forest areas. Be aware this species is considered invasive in some regions.
Brittle wood and branch drop
Cause: Fast growth produces relatively soft, weak wood
Solution: Plant away from structures and parking areas. Prune to reduce canopy weight before typhoon season.
Shallow root system
Cause: Naturally spreading, surface-level roots
Solution: Plant at least 8-10 meters from buildings, sidewalks, and utility lines.
Scale insects on branches
Cause: Common pest in humid conditions
Solution: Spray with horticultural oil or neem oil. Minor infestations on mature trees are rarely harmful.
