Family: Asteraceae

Tagetes lucida (Sweet-scented marigold, Mexican mint marigold) is a perennial herb native to Mexico and Central America. This versatile plant boasts a wide range of uses. Its leaves can be brewed into a tea, which is traditionally used to alleviate symptoms of the common cold, intestinal gas, and diarrhea. Additionally, it is used to add flavor to various culinary delights such as chocolatl, meat dishes, egg dishes, soups, and sauces. Tagetes lucida serves as a natural dye and insect repellent as well. Some studies suggest it possesses antimicrobial properties.

In ancient Aztec culture, this plant held sacred significance. It was burned as incense in rituals and dedicated to the god Tlāloc, associated with rain and lightning. While Tagetes lucida is widely naturalized in tropical regions, it has not been documented as naturalized on any Hawaiian Islands thus far. Although it’s considered a weed in many areas, its negative impacts are not thoroughly understood. While its limited seed production may hinder its spread, its adaptability and quick maturation could pose challenges if it were to become naturalized in Hawai’i.

High Risk Traits:

• Native to, and able to spread in, regions with tropical climates
  
• Naturalized in tropical regions (but no evidence in the Hawaiian Islands to date)
  
• Reported to be a weed in a number of locations (but impacts are generally not specified)
  
• Other Tagetes species are invasive weeds
  
• Tolerates many soil types
  
• Reproduces by seeds (but may be rare in cultivation)
  
• May reach maturity in one growing season
  
• Seeds dispersed externally by animals and intentionally by people
  
• May resprout after cutting or damage

Low Risk Traits:

• Unarmed (no spines, thorns, or burrs)
  
• Non-toxic
  
• Ornamental
  
• Not reported to spread vegetatively
  
• Limited seed production in cultivation may limit spread
