Cibotium glaucum, the hāpu‘u pulu, is a species of fern in the family Cyatheaceae, native to Hawaii.[2][1] A slow-growing tree fern typically 6 to 10 ft (2 to 3 m) tall but reaching 25 ft (8 m), it is hardy in USDA zones 10 through 12.[3][2] Its fiddleheads are the source of the material pulu, which means "mulch" or "padding" in the Hawaiian language.[4] Women used pulu as an absorbent during their menstrual cycles.[5]
