The Story
Plant Bio
Leptospermum laevigatum, the coast tea tree, is a large evergreen shrub or small tree with a gnarled, twisted trunk and shaggy, peeling grey-brown bark. The open, weeping crown features small, leathery grey-green leaves and solitary, five-petaled white flowers that cover the branches from late winter through spring.
This coastal specialist is highly adapted to maritime exposure, salt spray, and sandy soils, making it an exceptional windbreak or sculptural specimen. In California, it must be planted with caution, as it has escaped cultivation to become an invasive threat in coastal dune systems.

Planting
How to Grow
- Select a planting site in full sun with sandy, loamy, or well-draining soil.
- Dig a hole twice as wide as the root ball and of equal depth, ensuring the crown sits level with the surrounding soil.
- Water deeply immediately after planting to settle the soil, then water infrequently once the root system is established.
- Apply a light layer of organic mulch around the base to retain moderate moisture, keeping the mulch clear of the trunk.
Pro Tip
Never cut back into old, leafless wood when pruning, as the plant lacks the ability to resprout from bare stems and will likely die.
Keep It Thriving
Care Guide
Do
- Grow in full sun to maintain a dense, healthy crown.
- Ensure the soil drains rapidly to prevent root rot.
- Prune lightly and regularly to shape the canopy or maintain a hedge.
Don't
- Do not cut back into old, bare wood, as it will not regenerate.
- Avoid planting in heavy, poorly drained clay soils or low-lying wet areas.
- Do not apply heavy, high-phosphorus synthetic fertilizers.

Common Questions
Coast Tea Tree questions
What zones can Coast Tea Tree grow in?
Coast Tea Tree 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.
Is Coast Tea Tree deer resistant?
Not reliably. Deer may browse Coast Tea Tree, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Coast Tea Tree bloom?
Coast Tea Tree typically blooms in late winter through spring. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Coast Tea Tree need full sun?
Coast Tea Tree does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Coast Tea Tree drought tolerant?
Yes — once established (usually after the first full season), Coast Tea Tree handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
