Family: Myrtaceae

High Risk Traits:

• Native to Australia, a region with climates similar to Hawaiʻi
  
• Tolerant of drought and poor, sandy soils
  
• Fast-growing shrub under favorable conditions
  
• Produces abundant flowers and seeds
  
• Widely cultivated and frequently moved through the horticultural trade
  
• Can persist without intensive care once established
  
• Potential to escape cultivation in suitable habitats

Low Risk Traits:

• Not currently known to be naturalized in Hawaiʻi
  
• Generally short-lived compared to invasive woody plants
  
• Lacks specialized dispersal mechanisms (e.g., wind- or bird-adapted seeds)
  
• Typically grown in managed landscapes or as a cut-flower crop
  
• No documented history of severe invasiveness globally
  
• May require specific soil drainage conditions for optimal growth
