Family: Scrophulariaceae

High Risk Traits:

• Elevation range exceeds 1000 m, demonstrating environmental versatility
  
• Grows in tropical and temperate climates
  
• Other species have become invasive
  
• Tolerates many soil types
  
• Reproduces by seeds
  
• Hybridizes with other Buddleja species
  
• Seeds dispersed by wind, secondarily by water and intentionally by people
  
• Able to coppice and resprout after cutting
  
• Limited ecological information may reduce accuracy of risk prediction

Low Risk Traits:

• No reports of invasiveness or naturalization, but no evidence of widespread introduction outside native range
  
• Unarmed (no spines, thorns, or burrs)
  
• Ornamental
  
• Dioecious (requires male and female plants to produce viable seed
  
• Herbicides may provide effective control
