Family: Apocynaceae

High Risk Traits:

• Thrives in tropical climates
  
• Naturalized in Australia and possibly Antigua, West Indies
  
• Reported as a weed in Australia and Antigua, West Indies, but no negative impacts described
  
• Other Allamanda species have become invasive
  
• Sap toxic to animals and people
  
• Toxic sap likely reduces palatability
  
• Scrambling, potentially smothering, growth habit
  
• Seeds, when produced, dispersed by wind and intentionally by people
  
• Suckers profusely (can become problematic in gardens)
  
• Tolerates repeated pruning

Low Risk Traits:

• Unarmed (no spines, thorns or burrs)
  
• Ornamental
  
• Self-incompatible
  
• Reaches maturity in 4+ years (but able to spread vegetatively)
  
• Limited seed set in cultivation makes long-distance or accidental dispersal unlikely
