Growing notes

  • Bast fibre extracted from stems by chemical or mechanical degumming — the gum content is unusually high and is the principal processing difficulty
  • Fibre is among the strongest and most resistant to bacteria of any natural plant fibre
  • Three to six cuts per year possible in warm climates — the only major plant fibre that is harvested multiple times per season
  • Foliage looks like stinging nettle (Urtica dioica, already in the database) but the plant has no sting
