Family: Zingiberaceae

Alpinia hainanensis is a member of the ginger family (Zingiberaceae) valued for its lush foliage and ornamental qualities. Native to China (Southeast), Hainan, and Vietnam, this species produces broad, glossy leaves and forms dense clumps that make it a striking choice for tropical landscaping. Like other ornamental gingers, it adds texture and greenery to gardens and is often used as an accent plant, background planting, or to create a natural screen in shaded areas.

In Hawaiʻi, Alpinia hainanensis is only found in cultivation and has not been observed naturalizing in the wild. While it does not currently pose an invasive threat, gardeners should remain mindful of its potential to spread in climates similar to Hawaiʻi. Practicing responsible cultivation, including careful disposal of cuttings and plant material, will help ensure that this attractive species remains a safe and well-managed addition to local landscapes.

High Risk Traits:

• Thrives in tropical climates
  
• Other Alpinia species have become invasive weeds
  
• Reproduces by seeds and rhizomes
  
• Self-compatible, but primarily outcrossing
  
• Reaches maturity in 2 years
  
• Seeds, if produced, likely dispersed by birds and intentionally by people
  
• May be able to resprout from cutting of rhizomes
  
• Limited information reduces accuracy of risk predication

Low Risk Traits:

• No reports of invasiveness or negative impacts
  
• Unarmed (no spines, thorns or burrs)
  
• Ornamental and medicinal uses
  
• Pollinator limited
  
• Limited production of seed may minimize risk of accidental or long-distance dispersal
