Family: Bignoniaceae

High Risk Traits:

• Thrives and spreads in regions with tropical climates
  
• Naturalized in Queensland, Australia (but no evidence in the Hawaiian Islands to date)
  
• Unconfirmed report that plant may be an allergen
  
• Tolerates many soil types
  
• Reproduces by seeds
  
• Self-compatible
  
• Fast growth rate
  
• Seeds dispersed by wind and through intentional cultivation
  
• Seeds may form a persistent seed bank (up to 4 years)
  
• Tolerates heavy grazing, mowing and fire

Low Risk Traits:

• No reports of negative impacts where grown
  
• Unarmed (no spines, thorns, or burrs)
  
• Thrives in full sun and high light environments (dense shade may inhibit spread)
  
• Seeds lose viability after 150 days of storage (unlikely to form a persistent seed bank)
