Species Information
Kou is a canoe plant brought by Native Hawaiians and spread across the Hawaiian Islands. This species was valued as a carving wood due to the beauty of its grain and ease of cutting and carving. Medicinally, Kou was used to treat ‘ea (thrush). This tree can be distinguished by showy orange flowers that are one to two inches in diameter. Its flowers are used in lei.
Kou thrives in sunny, sandy, and salty shoreline habitats, providing shade and attracting pollinators.
It is sometimes confused with the Florida Cordia sebestena (Geiger tree), but kou’s flowers are softer orange (Geiger’s are bright red-orange), and its wood is lighter and smoother. Kou is native and non-invasive, while the Geiger tree is an introduced species.
