Family: Lamiaceae

High Risk Traits:

• Broad climate suitability (grown in temperate, Mediterranean, and tropical climates)
  
• Naturalized in Bulgaria, Crimea, Azores, Canary Islands, Cape Verde, Bermuda, Texas, and Central Mexico (but no evidence in the Hawaiian Islands)
  
• May be allelopathic
  
• Rarely eaten by browsing and grazing animals (generally unpalatable for much of the growing season)
  
• Generally non-toxic, but may cause contact dermatitis to some people
  
• Contains highly flammable oils and may increase fire risk in arid, and fire prone habitats
  
• Reproduces by prolific seed production
  
• Can hybridize with other Rosmarinus species
  
• Potentially self-compatible
  
• Reaches maturity in 2 years
  
• May be spread by vehicles in agricultural settings where the species is commercially grown
  
• Older plants seed prolifically
  
• Tolerates heavy pruning

Low Risk Traits:

• No reports of negative impacts where cultivated
  
• Unarmed (no spines, thorns, or burrs)
  
• Non-toxic to animals
  
• Thrives in high light environments (dense shade may inhibit ability to spread)
  
• Not reported to spread vegetatively
  
• Lacks mechanisms for long-distance seed dispersal
