Griselinia littoralis
Griselinia littoralis, also known as broadleaf, is a hardy evergreen shrub or small tree native to New Zealand. With its glossy, leathery leaves and dense growth habit, this adaptable species thrives in challenging coastal conditions while also performing well in urban environments. Valued for its wind tolerance, attractive foliage, and ability to function as both a specimen tree and a hedge plant, Broadleaf has become an important species for both ecological restoration and ornamental landscaping throughout New Zealand. native trees

| Scientific Name | Griselinia littoralis |
|---|---|
| Height | Up to 10 m (33 ft) as a tree, smaller as a shrub |
| Spread | 3–5 m (10–16 ft) wide |
| Water Needs | Low to moderate; drought-tolerant once established |
| Light | Full sun to partial shade |
| Frost Tolerance | High; tolerates heavy frosts |
| Salt Tolerance | Very high; excellent coastal tolerance |
| Growth Rate | Fast |
| Lifespan | Long-lived; decades in suitable conditions |
Griselinia littoralis is found throughout New Zealand from sea level up to 900m altitude, ranging from the far north to Stewart Island. It is particularly abundant in coastal areas due to its exceptional tolerance of salt-laden winds and exposed conditions. In the North Island, it tends to grow at higher altitudes than in the South Island, where it is more widespread.

The ecology of Griselinia involves its interactions with other species and its role in ecosystem processes. Understanding these relationships helps in conservation and cultivation.
Griselinia has various practical and ornamental uses. From traditional Māori applications to modern landscaping, this versatile plant serves multiple purposes.
Historically, Griselinia was used by Māori for medicinal purposes, food, and cultural practices. These traditional uses reflect the deep knowledge of native plants.
Spring is the ideal time to plant Griselinia as the soil warms and new growth begins. Water regularly to establish roots and apply a light mulch to retain moisture.
During summer, Griselinia may require additional watering during dry spells. Monitor for pests and provide shade if needed in hot climates.
Autumn is perfect for transplanting Griselinia as the cooler temperatures reduce stress. Reduce watering as growth slows.
Winter care for Griselinia involves minimal maintenance. Protect from severe frosts if necessary and avoid overwatering.
Prune Griselinia littoralis in late winter or early spring to maintain shape and encourage dense growth. Regular trimming is recommended for hedges. Remove any dead, damaged, or crossing branches as needed.
The best time to plant Griselinia is during spring or autumn when soil temperatures are moderate and rainfall is reliable.
Dig a hole twice the width of the root ball and slightly deeper. Place Griselinia in the hole, backfill with soil, and water thoroughly. Mulch around the base to retain moisture.

Griselinia littoralis has a rich history in New Zealand's natural and cultural landscape:
Today, Broadleaf is valued both for its ecological role and as a versatile landscaping plant. It is extensively used in coastal restoration projects, urban landscaping, and as a hardy hedge or screen plant. Its ability to withstand challenging conditions while maintaining an attractive appearance makes it one of New Zealand's most practical native plants. The species continues to gain popularity internationally in regions with mild oceanic climates, where it is prized for its salt and wind tolerance.
Broadleaf is generally very resilient to pests and diseases when grown in appropriate conditions. Its natural adaptations to harsh coastal environments make it one of the more trouble-free native plants. Most issues can be prevented by providing good drainage and appropriate light levels.
Create a multi-functional privacy screen by planting Griselinia littoralis as a backdrop, then layering with other native species in front. Start with Griselinia spaced at 1m intervals, then add mid-height shrubs like Coprosma repens or Corokia cotoneaster in front, followed by lower-growing Hebe species and native grasses like Carex or Chionochloa flavicans. This creates not only an effective wind and privacy barrier but also a diverse habitat for native birds and insects. The different leaf textures and colors provide year-round interest, while the layered approach creates a more natural-looking boundary than a single-species hedge. For coastal properties, this combination is particularly effective as all these species have good salt tolerance.
Kōhūhū is a versatile native shrub or small tree with wavy leaves and dark flowers, commonly paired with broadleaf in mixed native plantings for hedges and shelter.
