• Broad climate suitability (but not tropical)
  
• Widely naturalized

• Related Antirrhinum species have become invasive
  
• Possibly unpalatable to animals
  
• Tolerates many soil types
  
• Reaches maturity in under 1 year
  
• Prolific seed production
  
• Small seeds spread by wind and possibly other vectors

• Grows in temperate and Mediterranean climates
  
• Despite designation as weedy, no evidence of negative or detrimental impacts have been explicitly demonstrated
  
• May require full sun
  
• Ornamental flowers
  
• Self-incompatible (although certain cultivars reported to be self-compatible)
  
• Herbicides may provide effective control
