Growing notes

  • Native to eastern Australian subtropical rainforest — NSW, Queensland, and parts of Cape York
  • Distinct from the true frangipani Plumeria rubra already in the database — different family (Pittosporaceae, not Apocynaceae), no milky sap, and a much narrower tree habit
  • Intensely fragrant on warm spring afternoons — among the most fragrant Australian natives
  • Slender upright habit suits narrow garden positions
  • Not reliably hardy outdoors in Canada — Canadian zone values shown represent the system maximum and do not imply garden cultivation north of the warmest coastal pockets.
