• Reproduces by wind- and gravity-dispersed seeds
  
• Seeds also reported to be dispersed by vehicles
  
• Seeds may form a persistent seedbank
  
• Resprouts after fire

Low Risk Traits:

• A temperate species unlikely to spread in tropical islands, except possibly at higher elevations
  
• No reports of invasiveness or naturalization, but limited evidence of introduction outside native range
  
• Unarmed (no spines, thorns, or burrs)
  
• Non-toxic
  
• Not reported to spread vegetatively
  
• Reaches maturity in >3 to 6 years
