Growing notes

  • Inner bark fibre stripped from young one-year stems, beaten into thin papery sheets — the basis of Japanese washi paper (kozo), Korean hanji, Chinese xuan paper, and Polynesian tapa / kapa / siapo barkcloth
  • WARNING: Listed INVASIVE across much of the southeastern United States, parts of Africa, and Pakistan — root suckers spread aggressively from disturbed ground, do not plant where unwanted suckering cannot be tolerated
  • Distinct from the edible mulberries Morus alba and M. nigra (already in the database) — the fruit of paper mulberry is technically edible but rarely eaten
  • Fast growing — coppiced annually for best fibre quality
