About

Hibiscadelphus wilderianus, also known as the Maui hau kuahiwi, is an extinct species of flowering plant in the family Malvaceae that was endemic to the island of Maui in Hawaii.

In 2019, American biotechnology company Ginkgo Bioworks recreated the scent of Hibiscadelphus wilderianus's flower for a commercial fragrance line using DNA sequenced from the sole existing herbarium specimen.

Where it grows

Hibiscadelphus wilderianus's type specimen was found at 800 meters (2,265 feet) elevation in the dry forest lava fields of Auwahi on the rocky, dry southern slopes of Mount Haleakalā on Maui. Being on the leeward side of Mount Haleakalā, this region is relatively arid, receiving only 20 to 60 inches of rainfall annually.
