Alpinia purpurata (Vieill.) K. Schum.
Red Ginger, Jungle Queen, Jungle King, Opuhi Uteute, Gengibre Rojo, Tahitian Ginger, Ostrich Plume
This very showy flower appears in red (“jungle king”) and pink (“jungle queen”). Red ginger is native to New Caledonia, New Hebrides, Yap, British Solomon Islands Protectorate, Bismark Archipelago, and Bougainville. It was introduced to Hawai‘i prior to 1930, where it is now naturalized. In Hawai‘ian, red ginger is known as ‘awapuhi ‘ula‘ula.
Identification: Leaves are oblong, large, and shiny, on cane-like stems; plants can reach 9' (2.7 m) in height. The bright red or pink flower stalks, up to 12" (30 cm) long, are actually bracts—the plant produces inconspicuous white flowers.
