Hawaiian White Hibiscus Facts
- Firstly, the truly stunning Hawaiian White Hibiscus represents yet another rare plant species native to a small geographic range. Quite sadly, the gorgeous species exists on only two islands.
- Secondly, however, even in these locations, this dazzling beauty exists only within a rather specific habitat type. Unfortunately, this fact also renders it highly vulnerable to threats to its existence.
- These primarily include, but are not limited to habitat loss and, of course, climate change. Further, the habitat loss comes largely in the form of man’s use of its habitat for the construction of homes.

Hawaiian White Hibiscus Physical Description
Most notably, the stunningly beautiful Hawaiian White Hibiscus grows in either of two forms. As a result of this ability, it develops as either a small tree or shrub. This places it, much like the Devil’s Walking Stick among the few plants with this versatility.
Furthermore, in height, it averages between 15-20 ft (4.6-6.1 m). However, exceptional individuals sometimes reach as much as 30 ft (9.2 m). Also, the crowns of these trees often grow as large as 20 ft (6.1 m) in diameter. Its appearance also varies greatly between individual specimens and may be either compact or open in structure.
The leaves typically develop smooth and possess slightly toothed edges that average roughly 5 in (12.7 cm) in length. Meanwhile, the flowers appear white, grow singly, and may be as much as 4 in (10 cm) wide when open.

Hawaiian White Hibiscus Distribution, Habitat, and Ecology
First of all, as its very name suggests, the Hawaiian White Hibiscus evolved as native to Hawaii. However, even there it has a limited range, only appearing on the two islands of Oahu and Moloka’i.
Further, it also requires a highly specific habitat to thrive. only serving to compound its precarious position. In its native range, this consists of the very wet forest regions in the mountain areas of these two islands.
But, three distinct subspecies of this beautiful plant, each physically quite similar, also exist. One grows only in the mountains of Oahu, at elevations ranging between 390-2,500 ft (119-762 m).
Another of these typically prefers only altitudes between 650-2,200 ft (198-670 m). The third subspecies, like the Hawaiian White Hibiscus itself, also remains extremely rare. It grows only in a few valleys on the island of Moloka’i.
