Family: Strelitziaceae

Origin, Description & Uses
Strelitzia juncea, commonly known as the rush-leaved bird-of-paradise, is native to the Eastern Cape region of South Africa. This striking ornamental plant is closely related to the more familiar bird-of-paradise but is distinguished by its upright, cylindrical, reed-like leaves rather than broad banana-like foliage. Mature plants produce dramatic orange and blue flowers that resemble the head and crest of an exotic bird. Because of its unique architectural form, drought tolerance, and long-lasting blooms, Strelitzia juncea is widely cultivated in tropical, subtropical, and warm temperate landscapes. It is commonly used as a specimen plant, accent planting, or container specimen in gardens and public landscapes.

Risks & Threats
Strelitzia juncea is considered a low-risk species for Hawaii. It has a relatively slow growth rate, limited natural spread, and is not known to form invasive populations or significantly impact native ecosystems. The plant primarily reproduces through seed or division and typically remains confined to cultivated areas. While gardeners should always monitor ornamental plants for unexpected spread, there is currently little evidence that Strelitzia juncea poses a threat to Hawaii’s natural environments. Responsible cultivation and proper disposal of garden waste can help ensure it remains a safe and attractive landscaping choice.

High Risk Traits:

• Unpalatable go browsing animals such as deer and rabbits (potential competitive advantage)
  
• Seeds possibly toxic
  
• Reproduces by seeds
  
• Seeds dispersed by birds, mammals and intentionally by people
  
• Able to resprout after cutting and pruning

Low Risk Traits:

• No reports of invasiveness or naturalization
  
• Unarmed (no spines, thorns, or burrs)
  
• Ornamental
  
• Requires birds for pollination and seed set (pollinator limitations may result in reduced seed set)
  
• Not reported to spread vegetatively
