Notes: This species of Hibiscus features narrow-petaled red flowers which are constantly in bloom. In old Hawai‘i, the wood was used to make a fine charcoal. Native Hibiscus (both red and white) were grown near the homes of early Hawaiians for their flowers. These flowers were fashioned into striking temporary lei, which only lasted a day. Medicinally, koki‘o ‘ula‘ula was mixed with other plants and consumed for blood purification, and the leaves were chewed and swallowed as a laxative. Koki‘o ‘ula‘ula makes a great hedge or screening plant within a Hawaiian landscape. This species is somewhat drought tolerant, but should be protected from strong winds.
