Family: Solanaceae

Brugmansia arborea, commonly known as angel’s trumpet or angel’s tears, is a small tree or large shrub native to the Andean regions of South America. It is prized in gardens for its dramatic, pendulous, trumpet-shaped flowers, which are typically white and release a strong, sweet fragrance—especially in the evening. This ornamental plant is often grown for its showy blooms and tropical aesthetic, making it a popular choice in landscapes and private gardens. Historically, Brugmansia species have also held cultural and ceremonial significance in parts of their native range.

In Hawai‘i, Brugmansia arborea is not currently known to be invasive, but it does possess traits that warrant attention. Like other Brugmansia species, it produces abundant seed, can resprout from cuttings, and grows well in a range of conditions. All parts of the plant are highly toxic if ingested, which is an additional concern for households with pets or children. While it is not considered a major environmental threat at this time, continued observation is recommended to ensure it does not naturalize or negatively impact Hawai‘i’s ecosystems.

High Risk Traits:

• Able to grow in regions with tropical climates
  
• Reported to be naturalized in South Africa, and possibly the Galapagos
  
• Other Brugmansia species have become invasive
  
• Unpalatable to browsing and grazing animals
  
• Toxic to animals and humans
  
• Tolerates many soil types
  
• Reproduces by seeds
  
• May hybridize with other Brugmansia species
  
• Self-compatible
  
• Seeds dispersed by wind and intentionally by people
  
• Able to resprout after pruning or removal of above ground vegetation

Low Risk Traits:

• Despite naturalization, no reports of detrimental impacts to date
  
• Unarmed (no spines, thorns or burrs)
  
• Ornamental
  
• Not reported to spread vegetatively
  
• Seeds reported to lose viability quickly
  
• Seedling production in wild reported to be rare, despite production of viable seeds
