Dubautia plantaginea, known as plantainleaf dubautia or na'ena'e, is a rare Hawaiian aster that ranges from a small shrub to a tree up to about 7 m tall, depending on subspecies. Two of its three subspecies are endangered, so it is mainly of interest to conservation and native-plant collectors rather than general home gardeners.

About

Dubautia plantaginea is a rare species of flowering plant in the aster family known by the common name plantainleaf dubautia. It is endemic to Hawaii where it is the only member of the silversword alliance that is found on all six of the largest islands (Kauaʻi, O'ahu, Moloka'i, Lana'i, Maui, Hawai'i). Two of the three subspecies are rare and endangered. Like other Dubautia this plant is called na`ena`e.

This plant varies in morphology, taking the form of a small shrub to a tree up to 7 meters tall. There are three subspecies. The dwarf subspecies, ssp. humilis, is endemic to Maui, where there is only one population consisting of about 50 plants. This subspecies was federally listed as an endangered species in 1999. The ssp. magnifolia is a shrub or a tree which is endemic to Kauaʻi, where there are no more than 2 populations remaining. It was listed as endangered in 2010.
