Family: Linaceae

Linum flavum (golden flax, yellow flax) is a woody perennial native to central and southeastern Europe. Yellow flax is sometimes cultivated as an ornamental plant in gardens and landscapes due to its attractive flowers. It is suitable to be planted in an alpine garden or a rock garden. This plant has not been documented as naturalized in any Hawaiian Islands to date.

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
