Cyanea angustifolia
Also called `aku
Cyanea angustifolia is a shrub in the genus Cyanea that is endemic to Hawaiʻi. In Hawaiʻi, it is referred to as ʻAku as well as Hāhā, which is the term for the generalized Cyanea genus. C. angustifolia was a food source during times of food scarcity for the Hawaiians. This shrub is characterized by specialized flower shapes and it is found at higher elevations in wet environments.
C. angustifolia can be found on Oʻahu, commonly in the Ko’olau Mountains and scarcely in the Wai’anae Range. It can also be found on eastern Molokaʻi and Lānaʻi. Additionally, they can be found in northern areas of West Maui. Wet conditions are preferred for the survival of C.angustifolia. This plant's preferred habitat elevation ranges from 45 meters to over 760 meters, growing in mesic forests, mesic valleys, and wet forests.
