Growing notes

  • Leaf fibre extracted by retting or by scraping — historically used for cordage, sandals, and basketry by southeastern Native American peoples
  • White curling marginal threads (filaments) on the leaves give rise to both the species name and the common name "Adam’s needle"
  • Among the hardiest yuccas — succeeds well into USDA zone 4
  • Drought tolerant once established — excellent on poor sandy soils
