The Story
Plant Bio
Callitris glaucophylla, the white cypress-pine, is an evergreen coniferous tree native to mainland Australia, characterized by its glaucous, blue-grey foliage and a narrow, pyramidal habit when young. Over time, the crown spreads into a broad columnar form supported by a single main trunk, bearing small, woody female cones with thin scales.
This species is distinguished by its exceptional drought tolerance and highly aromatic, scale-like branchlets arranged in whorls of three. The foliage displays a striking contrast between the bright green of new spring growth and the mature, silvery-blue needles.

Planting
How to Grow
- Select a planting site in full sun with sandy, exceptionally well-drained soil.
- Dig a hole twice as wide as the root ball but no deeper, ensuring the root flare sits level with the surrounding soil.
- Backfill with native soil without adding organic amendments, pressing firmly to eliminate air pockets.
- Water deeply immediately after planting to settle the soil, then withhold irrigation once established to prevent root rot.
Pro Tip
Never prune past the green foliage line into bare, brown wood, as this conifer cannot regenerate new growth from old wood. Ensure the soil drains rapidly, as standing water or heavy, waterlogged clay will quickly induce fatal root rot.

Care Guide
Do
- Plant in a position with excellent air circulation to minimize fungal twig blights.
- Use a low-phosphorus native fertilizer sparingly if growing in a container.
- Protect young trees from browsing rabbits and deer with physical cages.
Don't
- Do not overwater or plant in low-lying areas prone to standing water.
- Never prune back into bare, leafless wood.
- Avoid heavy clay soils that retain moisture around the root zone.

Common Questions
White Cypress-Pine questions
What zones can White Cypress-Pine grow in?
White Cypress-Pine is hardy in USDA Zones 8–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is White Cypress-Pine deer resistant?
Not reliably. Deer may browse White Cypress-Pine, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does White Cypress-Pine bloom?
White Cypress-Pine typically blooms in spring through spring. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does White Cypress-Pine need full sun?
White Cypress-Pine does best in full sun (6+ hours).
Is White Cypress-Pine drought tolerant?
Yes — once established (usually after the first full season), White Cypress-Pine handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
