Family: Fabaceae

High Risk Traits:

• Broad climate suitability (but may be restricted to higher elevation of tropical and subtropical islands)
  
• Naturalized on Maui, Hawaiian Islands and widely naturalized elsewhere
  
• A disturbance and minor crop weed
  
• Other Trifolium species are invasive
  
• Not toxic, but may cause mechanical damage to horses
  
• Host of crop pathogens
  
• Tolerates many soil types
  
• Reproduces by seeds
  
• Self-compatible (but primarily outcrossing)
  
• Annual (reaches maturity in 1 growing season)
  
• Seeds dispersed by animals and intentionally by people
  
• Seeds able to be stored for extended periods; May form a persistent seed bank

Low Risk Traits:

• Despite reports of invasiveness and naturalization, impacts are unspecified; generally regarded as a desirable plant
  
• Unarmed (no spines, thorns, or burrs)
  
• Provides fodder for livestock
  
• Requires full sun
  
• Not reported to spread vegetatively
  
• Herbicides, mowing and tillage may provide effective control
