Family: Crassulaceae

High Risk Traits:

• Thrives in tropical climates
  
• Possibly naturalizing on Maui, Hawaiian Islands (confirmation needed)
  
• Other Kalanchoe species have become invasive
  
• Toxic to livestock
  
• Shade-tolerant
  
• Tolerates many soil types
  
• Forms dense stands
  
• Small seeds dispersed by wind and possibly other means
  
• Each leaf is capable of producing a new plant when it drops to the ground
  
• Limited ecological information makes accurate risk prediction difficult

Low Risk Traits:

• No confirmed reports of invasiveness elsewhere (possibly due to limited cultivation outside native range)
  
• Unarmed (no spines, thorns or burrs)
