Hapu‘u fern

A hapuu fern on the Big Island
Hapu‘u ferns are endemic to Hawaii and can grow to 25 feet high, depending on the type. I like how the fronds uncurl, gradually revealing more details. The golden brown hair is called pulu. I found these in Hawaii Volcanoes National Park, which is one of the places where the fern grows best.
