Family: Geraniaceae

High Risk Traits:

• Elevation range exceeds 1000 m, demonstrating environmental versatility
  
• Able to grow in tropical climates
  
• Naturalized on Kauai, Maui, and Hawaii, Hawaiian Islands
  
• Other Geranium species have become invasive
  
• Shade-tolerant
  
• Reproduces by seeds
  
• Hybridizes with other Geranium species
  
• Perennial, but able to reproduce in one growing season
  
• Small seeds, possibly spread through ballistic dispersal or by other means

• Able to resprout after fire

Low Risk Traits:

• Weedy, but impacts generally not specified in introduced range
  
• Unarmed (no spines, thorns or burrs)
  
• Not reported to spread vegetatively
  
• Limited ecological information makes accurate risk prediction difficult
