Family: Linaceae

High Risk Traits:

• Elevation range exceeds 1000 m, demonstrating environmental versatility
  
• Naturalized in regions with tropical climates
  
• Naturalized on Kauai, Maui and Hawaii (Hawaiian Islands); widely naturalized elsewhere
  
• A weed of lawns, disturbed areas, pastures, and potentially of agriculture
  
• Other Linum species are weeds
  
• Seeds may contain toxic compounds
  
• Tolerates many soil types
  
• Reproduces by seeds
  
• Self-compatible
  
• Reaches maturity in one year
  
• Seeds dispersed as a contaminant, possibly by water, and possibly attached to animals, equipment and vehicles
  
• Viable seeds survive gut passage after consumption by horses

Low Risk Traits:

• Despite widespread naturalization and reports of weediness, impacts appear to be minimal, or are generally innocuous
  
• Unarmed (no spines, thorns or burrs)
  
• Shade-intolerant
  
• Not reported to spread vegetatively
  
• Herbicides may provide effective control
