• Cited as an agricultural weed (unconfirmed)
  
• Other Harrisia species are invasive weed
  
• Spiny
  
• Shade-tolerant
  
• Reproduces by seeds and vegetatively by stem fragments
  
• Seeds dispersed by birds, other frugivorous animals and intentionally by people
  
• Seeds of related species form persistent seed banks
  
• Members of genus able to resprout after cutting
  
• Limited ecological information may reduce accuracy of risk prediction

Low Risk Traits:

• No confirmed reports of invasiveness or naturalization, but no evidence of widespread introduction outside native range
  
• Palatable fruit
  
• Non-toxic
  
• Ornamental
  
• Herbicides provide effective control of related taxa
