Hapu'u, also known as the Hapu'u tree fern or Cibotium glaucum, is a large, native fern found in the tropical forests of Hawaii. It can grow up to 30 feet tall and features a thick, upright trunk topped with a crown of large, feathery fronds. Hapu'u thrives in moist, shaded environments and plays a vital role in the ecosystem by providing habitat for various species. The Hapu'u fern is culturally significant to the Hawaiian people, often used in traditional practices and crafts. Its fronds are sometimes woven into lei or used for thatching roofs. Additionally, Hapu'u contributes to soil stability and helps prevent erosion in its native habitat.
