Family: Linaceae

High Risk Traits:

• Reported to be naturalized in Japan and Australia (no reports from the Hawaiian Islands to date)
  
• Other Linum species are weeds
  
• Seeds and parts of related species reported to contain toxins
  
• Tolerates many soil types
  
• Reproduces by seeds
  
• Seeds dispersed by cultivation, and possibly water. Otherwise, no special adaptations for dispersal (autochory)
  
• Seeds may form a persistent seed bank (at least 1 year)

Low Risk Traits:

• No confirmed reports of detrimental impacts where cultivated
  
• Unarmed (no spines, thorns, or burrs)
  
• Palatable to some grazing animals
  
• Grows best in high light environments (dense shade may inhibit spread)
  
• Self-incompatible
  
• Not reported to spread vegetatively
  
• Herbicides may provide effective control if needed
