Family: Iridaceae

High Risk Traits:

• Thrives in tropical climates
  
• Anecdotal reports of weediness in landscaping
  
• Unconfirmed reports of toxicity
  
• A host of the nettle caterpillar
  
• Shade-tolerant
  
• Tolerates many soil types
  
• Reproduces by seeds and vegetatively by plantlets
  
• Arillate seeds may be dispersed by birds, ants and intentionally planted by people
  
• Missing information on reproductive biology and seed ecology reduces accuracy of risk prediction

Low Risk Traits:

• Widely cultivated, with no reports of invasiveness or naturalization in natural areas or agricultural setting
  
• Unarmed (no spines, thorns, or burrs)
  
• May require specialized pollinators
