Family: Cunoniaceae

Ceratopetalum gummiferum (Christmasbush, New South Wales Christmas bush) is a tall shrub/small tree endemic to New South Wales. It is cultivated as a garden plant, a number of cultivars have been bred to vary in flower color and size, and are usually sold by specialist nurseries in Australia. The flowers and foliage are used as a cut flower and the plant is farmed commercially for that purpose. 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
  
• Casual, and potentially naturalized, in New Zealand
  
• Tolerates many soil types
  
• Reproduces by seeds
  
• Seeds dispersed by wind, and intentionally by people
  
• Resprouts after fire, and possibly cutting

Low Risk Traits:

• No reports of invasiveness or negative impacts outside native range
  
• Unarmed (no spines, thorns, or burrs)
  
• Non-toxic
  
• Not reported to spread vegetatively
  
• Seeds unlikely to be dispersed long distances
