The Story
Plant Bio
Pandanus tectorius is an evergreen, multi-branched small tree native to coastal northern Australia, characterized by a highly sculptural habit and thick, anchoring aerial prop roots at the base. The linear, strap-like leaves grow up to one metre long and are arranged in a distinctive, tight screw-like spiral at the branch tips.
This species is dioecious, producing fragrant male flower clusters wrapped in large cream bracts, or compact female spikes that develop into large, segmented fruits. It exhibits outstanding tolerance to coastal salt spray, high winds, and sandy soils, making it a primary stabilizing plant for exposed headlands.

Planting
How to Grow
- Choose a planting site in full sun with well-drained sandy, loamy, or clay loam soil.
- Dig a hole twice the width of the root ball and plant at the same depth as the nursery pot, ensuring the emerging prop roots are not buried.
- Water deeply to settle the soil around the roots and apply a light layer of mulch, keeping it clear of the main stem.
- Water regularly until established, after which the plant develops high drought tolerance.
Pro Tip
Never prune into bare, brown trunk wood as the plant cannot regenerate from old leafless stems, and avoid planting near pathways where the sprawling prop roots and sharp, serrated leaf margins will obstruct access.

Care Guide
Do
- Inspect the crown seasonally for signs of planthopper activity such as yellowing or sticky honeydew.
- Wear thick gloves and protective clothing when handling the plant to avoid cuts from the sharp, serrated leaf margins.
- Plant in a spacious area where the massive mature spread and aerial roots have room to expand.
Don't
- Do not prune into old, leafless wood, as this causes permanent branch dieback.
- Do not plant near underground drains, tight foundations, or narrow pathways.
- Do not drill multiple random holes into the trunk when attempting pest treatments, as this leads to trunk decay.

Common Questions
Screw Pine questions
What zones can Screw Pine grow in?
Screw Pine is hardy in USDA Zones 9–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
When does Screw Pine bloom?
Screw Pine typically blooms in spring through summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Screw Pine need full sun?
Screw Pine does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Screw Pine drought tolerant?
Yes — once established (usually after the first full season), Screw Pine handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
