Family: Arecaceae

Origin, Description & Uses
Gaussia attenuata, commonly known as llume palm or palma de sierra, is native to the Dominican Republic and Puerto Rico, where it grows in rocky limestone hills and dry coastal forests. This slender, elegant palm features a smooth, gray trunk and a graceful crown of arching, feather-like fronds. It produces small, ornamental fruits and is valued for its tidy, upright form. Because of its attractive appearance and tolerance for dry, well-drained soils, it is sometimes cultivated as an ornamental palm in tropical and subtropical landscapes, including gardens and collections focused on Caribbean flora.

Risks & Threats
This species is considered low risk and is not known to be invasive in Hawaii or other tropical regions where it is grown. It does not commonly spread beyond cultivation, and there is no evidence of significant ecological impacts. However, as with any introduced species, it is still advisable to plant responsibly and monitor for unexpected spread. Choosing appropriate planting sites and maintaining garden plants can help ensure it remains a safe and beneficial addition to the landscape.
