Family: Heliconiaceae

Origin, Description & Uses
Heliconia psittacorum, commonly known as parrot’s beak, is native to Central and South America. This tropical plant is prized for its striking, brightly colored bracts that resemble a parrot’s beak, and its lush green foliage adds dramatic texture to gardens and landscapes. Parrot’s beak is often grown as an ornamental plant, both outdoors in tropical climates and indoors in containers in cooler regions. Its long-lasting, vibrant flowers are popular in floral arrangements and landscaping for their exotic appearance.

Risks & Threats
Although Heliconia psittacorum is not currently known to be naturalized in the Hawaiian Islands, it possesses traits that are cause for concern. Its ability to spread vigorously through rhizomes and produce abundant seeds could allow it to establish in wild areas if introduced, potentially outcompeting native plants and altering habitats. On tropical islands, species with these traits can disrupt local ecosystems and threaten biodiversity. For this reason, if Heliconia psittacorum is being intentionally planted, it is recommended to consider a low risk or native alternative that provides similar ornamental value without posing ecological risks.

High Risk Traits:

• Naturalized beyond native range (Jamaica, Florida)
  
• Congeneric weed (H. bihai is controlled as a weed)
  
• Forms dense thickets (~60 shoots/m²)
  
• Shade tolerant
  
• Produces viable seeds
  
• Self-compatible
  
• Reproduces vegetatively by rhizomes
  
• Flowers within first year (8 months)
  
• Dispersed intentionally as ornamental
  
• Dispersed by water (rhizomes float)
  
• Dispersed by birds (fleshy fruits)
  
• Seeds survive gut passage
  
• Persistent seed bank (years of dormancy)
  
• Tolerates mutilation/clipping

Low Risk Traits:

• Not a garden, agricultural, or environmental weed
  
• No spines, thorns, or burrs
  
• No allelopathy or parasitism
  
• Non-toxic to animals and humans
  
• No fire hazard (moist tropical foliage)
  
• Requires specialist pollinators (hummingbirds)
  
• Low seed production (low fruit set)
  
• No unintentional dispersal
  
• No wind dispersal
