Family: Asteraceae

High Risk Traits:

• Widely naturalized
  
• Controlled as a weed in Australia
  
• Spiny form most common
  
• Hybridizes with other Carthamus species
  
• Reached maturity in <1 year (annual life cycle)
  
• Seeds may be accidentally dispersed

Low Risk Traits:

• Documented as a weed, but impacts minor or unspecified
  
• Palatable to grazing animals
  
• Non-spiny form exists
  
• Source of food and dye for humans
  
• Shade-intolerant
  
• Herbicides would likely provide effective control
