Family: Fabaceae

High Risk Traits:

• Adapted to tropical climates
  
• Broad climate suitability and elevation range
  
• Naturalized in Argentina (but no evidence in the Hawaiian Islands to date)
  
• A pioneer tree that could establish in open, disturbed habitats
  
• Other Senna species are invasive weeds
  
• Shade tolerant
  
• Tolerates many soil types
  
• Reproduces by seeds
  
• Self-fertile (autogamous)
  
• Fast growth rate (but time to maturity unknown)
  
• Seeds dispersed by autochory (self-dispersal), by mammals (internally), by ants (externally), potentially by water and through intentional cultivation
  
• Seeds may form a persistent seed bank

Low Risk Traits:

• Despite naturalization, negative impacts have not been reported to date
  
• Unarmed (no spines, thorns, or burrs)
  
• Non-toxic
  
• Grows best in high light environments (dense shade may inhibit spread)
