Gardenia brighamii is a species of flowering plant in the coffee family, Rubiaceae.[3][4] It is sometimes referred to by the common names nānū, naʻu, or forest gardenia, and is endemic to Hawaii.[5]
Description
Gardenia brighamii is a small tree, reaching a height of 5 m (16 ft).[5] The glossy, dark green leaves[6] are ovate, 2.2–10.5 cm (0.87–4.13 in) long and 1.5–5.5 cm (0.59–2.17 in) wide. The petals of the solitary, white flowers are fused at the base to form a tube 15–20 mm (0.59–0.79 in) in length and have six lobes.

Habitat and range
Forest gardenia inhabits tropical dry forests at elevations of 350–520 m (1,150–1,710 ft). It previously could be found on all main islands, but today populations only exist on Maui, Molokaʻi, Oʻahu, and Lānaʻi, and the Big Island.[5]
Conservation
The total population of G. brighamii is between 15 and 19 trees. There are only two plants in the wild on Oʻahu and one on the Big Island.[7] Major threats to the survival of this species include loss of dry forest habitat and the establishment of invasive species, such as fountain grass (Pennisetum setaceum).[5]
Uses
Native Hawaiians made kua kuku (kapa anvils)[5] and pou (house posts) from the wood of nānū.[7] A yellow kapa dye was derived from the fruit pulp.[8] The white, fragrant flowers are used in lei. Today, it is grown as an ornamental plant on the islands.[7]
