Family: Bignoniaceae

High Risk Traits:

• Thrives in tropical climates
  
• Elevation range exceeds 1000 m
  
• Naturalized in Australia and possibly elsewhere
  
• Classified as an environmental weed in Australia
  
• Other Bignonia species have become weedy and invasive
  
• Climbing and smothering growth habit
  
• Tolerates many soil types
  
• Seeds, if produced, are adapted to wind-dispersal
  
• Can spread vegetatively, and from discarded garden waste

Low Risk Traits:

• Unarmed (no spines, thorns or burrs)
  
• Non-toxic
  
• May requires full sun
  
• Possibly self-incompatible
  
• Requires specialized pollinators
  
• Seed production may be limited or absent outside native range, minimizing risk of long-distance dispersal
