Family: Fabaceae

High Risk Traits:

• Broad climate suitability
  
• Can grow, and potentially spread, in regions with tropical climates
  
• Sparingly naturalized on Hawaii island, widely naturalize elsewhere
  
• Weed of lawns roadsides and disturbed areas
  
• Occasional weed of crops (impacts ambiguous)
  
• Other Trifolium species are invasive weeds
  
• Potentially allelopathic
  
• May be mildly toxic to livestock under certain conditions
  
• Tolerates many soil types (not substrate limited)
  
• Forms dense swards (could compete with other desirable vegetation)
  
• Reproduces by seeds
  
• Self-fertile and self-pollination
  
• An annual, reaching maturity in <1 year
  
• Seeds dispersed internally by animals and through agricultural activities (i.e. potential soil and seed contaminant)
  
• Tolerates cutting and grazing

Low Risk Traits:

• Despite naturalization and reports of weediness, generally not regarded as a problematic agricultural or environmental weed in the Hawaiian Islands
  
• Unarmed (no spines, thorns or burrs)
  
• Provides fodder for livestock
  
• Ornamental
  
• Not reported to spread vegetatively
  
• Herbicides may provide effective control if removal is desired
