Family: Melastomataceae

High Risk Traits:

• Native distribution tropical and subtropical regions
  
• Elevation range exceeds 1000 m, demonstrating environmental versatility
  
• Thrives in tropical climates
  
• Naturalized on Hawaii Island
  
• Regarded as weedy in native range
  
• Other Tibouchina species are invasive
  
• Reproduces by seeds (ability to spread vegetatively unknown)
  
• Seeds dispersed by wind, gravity, water and intentionally by people

Low Risk Traits:

• No reports of invasiveness or naturalization elsewhere, but limited evidence of widespread introduction outside native range
  
• Unarmed (no spines, thorns or burrs)
  
• Seeds require light to germinate
  
• Ornamental
  
• Seeds non-dormant
  
• Herbicides provide effective control for other invasive Tibouchina species
