Family: Myrtaceae

Regelia megacephala (purple flowered Regelia) is a shrub native to Western Australia. This plant is considered rare or near threatened by Western Australian Government Department of Parks and Wildlife. It is used in gardens as an ornamental plant for low hedging and in streetscapes. It is an attractant for butterflies and birds and known for its vibrant flowers, which are used in the cut flower and foliage trade. This plant has not been documented as naturalized in any Hawaiian Islands to date.

High Risk Traits:

• Reproduces by tiny seeds
  
• Several members of the genus are self-compatible
  
• Serotinous; may form a persistent “canopy seed bank” until capsules dehisce following fire
  
• Gaps in biological and ecological information may reduce accuracy of risk prediction

Low Risk Traits:

• No reports of invasiveness or naturalization, but no evidence of widespread introduction outside native range
  
• Unarmed (no spines, thorns, or burrs)
  
• Non-toxic
  
• Not reported to spread vegetatively
