Growing notes

  • Narrow column to 15 m tall — provides effective windbreak from a small ground footprint, ideal for paddock boundaries and farmhouse shelter
  • Timber is naturally termite-resistant — historic preferred Australian outback flooring and framing timber for that reason
  • Drought tolerant and frost tolerant once established — succeeds across the inland Australian wheat belt where most conifers fail
  • Both the inland-form Callitris glaucophylla and the coastal C. columellaris (sometimes treated as a single species) are used interchangeably for shelter planting
