Family: Bignoniaceae

Origin, Description & Uses:
Tecomanthe dendrophila is a tropical woody climbing vine native to the Maluku Islands, New Guinea, and the Solomon Islands. It is admired for its vigorous growth, glossy green foliage, and large, showy tubular flowers that range from pink to reddish-purple, making it an attractive ornamental for trellises, arbors, and large garden structures. Like other members of the bignonia family (Bignoniaceae), it thrives in warm, humid climates and is primarily grown for its spectacular floral display in tropical and subtropical landscapes.

Risks & Threats:
Tecomanthe dendrophila is considered a low-risk species for Hawaiʻi. There is no evidence that it has become invasive or naturalized in the Hawaiian Islands or elsewhere, and it has not demonstrated the aggressive growth, prolific seed production, or widespread dispersal associated with invasive vines. As with any introduced plant, it should be monitored to ensure it remains confined to cultivated settings, but current evidence indicates that it poses little threat to native ecosystems when responsibly managed. Proper garden maintenance and preventing unwanted spread beyond planted areas are recommended as good horticultural practices.

High Risk Traits:

• Broad climate suitability (sea level to 1500 m in various forests)
  
• Native to tropical climates (Moluccas to New Guinea)
  
• Climbing vine, rapidly grows to 15 m (can smother structures)
  
• Cultivated intentionally as an ornamental
  
• Wind-dispersed winged seeds
  
• Tolerates partial shade

Low Risk Traits:

• No naturalization recorded outside native range
  
• Not reported as a weed (garden, agricultural, or environmental)
  
• Lacks spines, thorns, or burrs
  
• Non-toxic to humans and animals
  
• Low seed production in cultivation
  
• No vegetative spread
  
• No unintentional dispersal (not by water, animals, or as a contaminant)
