Family: Iridaceae

High Risk Traits:

• Broad climate suitability and elevation range
  
• Able to grow in tropical climates
  
• Naturalized on Oahu, Maui, and Hawaii (Hawaiian Islands), as well as Alabama, Louisiana, and Australia
  
• Other Gladiolus species are invasive weeds
  
• Geophyte
  
• Reproduces by seeds, corms and possibly bulbils
  
• Spread by wind-dispersed seeds and discarded bulbs, as well as by intentional planting
  
• Seeds able to be stored for extended periods; May form a persistent seed bank
  
• Limited biological and ecological information may reduce accuracy of risk prediction

Low Risk Traits:

• Despite naturalization, no documented reports of negative impacts to date
  
• Unarmed (no spines, thorns, or burrs)
  
• Corms palatable to animals (may be consumed by pigs)
  
• Ornamental
  
• Prefers full sun (may limit ability to spread into shaded habitats)
  
• Herbicides may provide effective control
