The Story
Plant Bio
Griselinia littoralis, known as New Zealand broadleaf, is an upright, dense evergreen shrub native to lowland and montane forests across New Zealand. The species is dioecious, bearing inconspicuous greenish-yellow spring flowers that develop into small purple-black berries on female plants if a male pollinator is nearby.
This species is distinguished by its thick, leathery, oval leaves that emerge in a bright lime-green shade before maturing to a glossy apple-green. It exhibits exceptional tolerance to coastal salt spray and wind, making it a highly reliable structural choice for seaside hedging.

Planting
How to Grow
- Select a planting site in full sun to partial shade with well-drained soil.
- Dig a hole twice the width of the root ball and to the same depth.
- Backfill with native soil, firming gently around the base to eliminate air pockets.
- Water thoroughly and apply a layer of organic mulch, keeping it clear of the stem.
Pro Tip
Prune with gentle, regular exterior clipping rather than hard structural stumping, as cutting back into thick, old bare wood results in sparse recovery and bare patches.
Keep It Thriving
Care Guide
Do
- Water regularly during prolonged dry spells until the root system is fully established.
- Apply a balanced, slow-release fertiliser in early spring to support new growth.
- Prune lightly once a year in mid-to-late spring after the main growth flush.
Don't
- Do not plant in poorly drained sites subject to winter waterlogging or stagnant wet feet.
- Do not prune hard into old, leafless interior wood as it struggles to re-shoot.
- Do not use heavy, high-phosphorus fertilisers designed for Australian Proteaceae.

Common Questions
New Zealand Broadleaf questions
What zones can New Zealand Broadleaf grow in?
New Zealand Broadleaf is hardy in USDA Zones 7–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
When does New Zealand Broadleaf bloom?
New Zealand Broadleaf 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 New Zealand Broadleaf need full sun?
New Zealand Broadleaf does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is New Zealand Broadleaf drought tolerant?
Yes — once established (usually after the first full season), New Zealand Broadleaf handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
