Family: Asteraceae

High Risk Traits:

• Broad climate suitability (Can grow in >5 hardiness zones)
  
• Widely naturalized
  
• A garden and disturbance weed
  
• Other Coreopsis species have become invasive
  
• Tolerates a wide range of soil conditions
  
• Can from dense stands that may potentially exclude other vegetation

• Annual – able to reach maturity in one growing season
  
• Seeds dispersed intentionally by people, by water movement, and possibly in soil

• A temperate species (may only be invasive at higher elevation in tropics)
  
• Unarmed (no spines, thorns or burrs)
  
• Palatable to grazing animals
  
• Not reported to be toxic
