RHS hardiness rating H3 −5 °C to 1 °C Plant needs at least this level of cold tolerance
Canadian plant hardiness zone Zone 9 −1 °C and warmer Plant tolerates down to this zone

Growing notes

  • Native to the Bunya Mountains and adjacent areas of southeastern Queensland
  • Large edible seeds (bunya nuts) — culturally significant to Aboriginal peoples, who historically held inter-tribal gatherings every 3 years when the trees produced mass crops
  • WARNING: Falling cones weigh 5–10 kg each and drop from 30 m+ height — site away from paths, parking, and seating; many Australian botanical gardens close off the area beneath bunyas during the bunya nut harvest
  • Eventually 40+ m — site for the very long term, only suitable for large open gardens, parks, and farms
  • 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.
