Family: Myrtaceae

Callistemon pallidus (lemon bottlebrush, yellow bottlebrush) is an upright evergreen shrub endemic to Eastern Australia. It is great for hedges, wall side borders, and a variety of different types of gardens. This plant has not been documented as naturalized in any Hawaiian Islands to date.

High Risk Traits:

• Able to grow, and potentially spread, in regions with subtropical climates
  
• Other Callistemon species reported to be naturalized
  
• Tolerates many soil types
  
• Reproduces by numerous, tiny seeds
  
• Seeds may be dispersed for short distances by wind and water
  
• Serotinous seeds retained on plants, may form a persistent “canopy seed bank”
  
• Able to resprout after cutting and fires

Low Risk Traits:

• No reports of invasiveness or naturalization in Hawaii or elsewhere in the world
  
• Unarmed (no spines, thorns, or burrs)
  
• Non-toxic
  
• Serotinous seeds unlikely to be accidentally dispersed
