High Risk Traits:

• Congeneric weeds exist
  
• Repeated introductions outside native range (India, Hawaii)
  
• Seeds adapted for wind dispersal (winged)
  
• Broad climate tolerance (sea level to 1600 m)
  
• Produces viable seed

• No evidence of naturalization outside native range
  
• Not documented as a weed (garden, agricultural, or environmental)
  
• No spines, thorns, or burrs
  
• Self-incompatible (late-acting)
  
• No vegetative reproduction
  
• Long generation time (4+ years to maturity)
  
• No unintentional dispersal or produce contamination risk
  
• Not bird- or water-dispersed
  
• No prolific seed production
