Growing notes

  • Native to higher elevations of the Andes (Ecuador, Peru, Bolivia, Argentina, Chile)
  • WARNING: More invasive than C. selloana in many regions — entirely female and apomictic, so every plant sets viable seed without a pollination partner; banned or restricted in California, Australia, New Zealand, and Hawaii; do not plant outside its native range
  • Distinct from C. selloana — jubata has smaller plumes, pinker colour, and is consistently more invasive
  • Razor-sharp leaf edges — handle with gloves
