Family: Lamiaceae

Clerodendrum paniculatum, commonly known as pagoda flower, is a striking tropical shrub native to Southeast Asia. It grows up to 3–4 meters tall and is prized for its dramatic, tiered clusters of bright red-orange flowers that resemble the layered roofs of a pagoda. Often planted in gardens and landscapes for its ornamental appeal, this plant can attract pollinators such as butterflies and hummingbirds, adding vibrant color and life to tropical settings. Its lush foliage and bold blooms make it a popular choice for decorative hedges and focal points in cultivated landscapes.

Although Clerodendrum paniculatum is not currently naturalized in Hawaii, it does exhibit traits that could pose ecological risks, such as vigorous growth and the potential to spread beyond cultivated areas. These characteristics warrant caution, as they may allow the plant to compete with native species or alter natural habitats if introduced widely. Further evaluation is recommended to ensure that planting this species will not negatively impact Hawaii’s delicate ecosystems.

High Risk Traits:

• Highly suited to tropical/subtropical climates
  
• Naturalizes outside native range
  
• History of repeated ornamental introductions
  
• Bird-dispersed fruits
  
• Reproduces vegetatively (root suckers)
  
• Resprouts after damage
  
• Congeneric species are weeds

Low Risk Traits:

• Not reported as invasive or a serious weed
  
• Low seed production in cultivation
  
• No specialized dispersal (wind/water/external attachment)
  
• Non-toxic to humans/animals
  
• Not allelopathic or parasitic
  
• No spines/thorns
  
• Not shade tolerant
