About Cibotium glaucum (Sm.) Hook. & Arn.
Cibotium glaucum (Sm.) Hook. & Arn., commonly called hāpu‘u pulu, is a species of tree fern belonging to the family Cyatheaceae. It is native to Hawaii. This is a slow-growing tree fern that usually reaches 6 to 10 feet (2 to 3 meters) tall, though it can grow up to 25 feet (8 meters) tall. It is hardy in USDA growing zones 10 through 12. Its unfurling young fronds, called fiddleheads, produce the soft material known as pulu. In the Hawaiian language, pulu means "mulch" or "padding". Historically, Hawaiian women used this pulu as an absorbent during menstrual cycles.
