David Orr contributed to this Plant Profile.
Hibiscus brackenridgei is Hawai`i's State flower and a member of the mallow family (Malvaceae). It is a sprawling shrub to small tree with beautiful yellow flowers with a maroon spot in the center. Hibiscus brackenridgei ssp. brackenridgei is currently known only from 7 populations with a total of less than 60 plants. They are found on the islands of Hawai`i, Maui and Lana`i in lowland dry to mesic forest and shrubland.
Threats such as habitat degradation and possible predation by pigs, goats, deer and cattle; competition with alien plant species; road construction; fire and random naturally occurring events have significantly reduced the number of populations and plant numbers and some cases extinction in some areas.
