Family: Apocynaceae

High Risk Traits:

• Broad elevation range (>1000 m) in tropical climates
  
• Grows and could potentially spread in regions with tropical climates
  
• Shade tolerant
  
• Climbing, and potentially smothering, growth habit
  
• Can regenerate from tuberous roots
  
• Reproduces by seeds and vegetatively by stem cuttings or aerial tubers produced along the stems
  
• Seeds dispersed by wind and through intentional cultivation

Low Risk Traits:

• No confirmed reports of naturalization or invasiveness, but more commonly cultivated indoors as an ornamental
  
• Unarmed (no spines, thorns, or burrs)
  
• Stems and tubers edible to animals and humans
  
• Non-toxic
  
• Specialized pollinator requirements may limit seed set and reduce risk of long distance, accidental dispersal
