Family: Arecaceae

Barrel Palm (Colpothrinax wrightii) is a small to medium-sized palm native to Cuba. It is known for its distinctive swollen, barrel-shaped trunk and elegant crown of feathery, fan-like leaves. This palm is often grown as an ornamental for its striking shape and tropical appeal, making it a popular choice for gardens, landscapes, and public spaces. Its slow growth and unique form add a sculptural element to plantings, and it is sometimes used in educational or conservation collections to showcase Caribbean flora.

While the barrel palm is not reported as invasive, it is important to be cautious when planting non-native palms in Hawai‘i, as palms can sometimes spread beyond intended areas. Currently, Colpothrinax wrightii is not known to be naturalized in the islands, and there are no major documented ecological threats. Nonetheless, careful monitoring is recommended to ensure it does not escape cultivation or compete with native species.

High Risk Traits:

• High tropical/subtropical climate suitability
  
• Ornamental use → intentional human dispersal
  
• Bird-dispersed seeds that survive gut passage

Low Risk Traits:

• No evidence of naturalization or weediness
  
• Not toxic, allelopathic, spiny, or fire-prone
  
• Low seed production; no seed bank; no vegetative spread
  
• Slow-growing; requires full sun; limited soil tolerance
  
• Not wind-dispersed; not a contaminant
