Family: Amaryllidaceae

High Risk Traits:

• Thrives in tropical climates
  
• Naturalized, and/or adventive in Puerto Rico and the West Indies
  
• Demonstrates allelopathic properties in laboratory settings
  
• Toxic to house pest if ingested
  
• Shade-tolerant
  
• Tolerates many soil types
  
• Geophyte (able to resprout from underground bulbs)
  
• Propagated, and possibly spread, by vegetative offsets

Low Risk Traits:

• Widely cultivated, with no reports of invasiveness or negative impacts within introduced range
  
• Unarmed (no spines, thorns or burrs)
  
• Ornamental
  
• Possibly sterile in cultivation
  
• Requires specialized pollinators (long-tongued moths)
  
• Self-incompatible
  
• Limited, to no, seed production makes inadvertent dispersal unlikely
