Gardenia brighamii, commonly known as nānū, naʻu, or forest gardenia, is a species of flowering plant in the coffee family, Rubiaceae, that is endemic to Hawaii.[3]
Description
Gardenia brighamii is a small tree, reaching a height of 5 m (16 ft).[3] The glossy, dark green leaves[4] 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.[3]
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.[5] 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).[3]
Uses
Native Hawaiians made kua kuku (kapa anvils)[3] and pou (house posts) from the wood of nānū.[5] A yellow kapa dye was derived from the fruit pulp.[6] The white, fragrant flowers are used in lei. Today, it is grown as an ornamental plant on the islands.[5]
