This rare subspecies of native white hibiscus is endemic to the wetter forests in the northern and northwestern valleys of Kauai and nowhere else in the world.
Endemic – Endagered
As with most hibiscuses, the Koki’o ke’oke’o can be trimmed into a beautiful and colorful hedge, but I think it looks better as a stand-alone plant to be admired from all directions.
It can handle full sun quite well but does best in partially shaded areas with filtered sunlight. Hint: Plant it in front of a dark background — such as a rock wall or ti hedge — to really show off the flowers!
The native white hibiscuses, which include Hibiscus arnottianus (found on Oahu and Molokai) and this species, H. waimeae, are the only naturally fragrant hibiscuses in the world.
