A landscaping or gardening project can be incredibly involved, requiring a lot of time and energy, both of which are in short supply in our busy modern lives. Fast growing evergreen trees provide a quick way to create a garden feature, a natural privacy screen, promote biodiversity and more. No matter what your needs, these recommendations are sure to suit, covering a variety of species that are readily available in this country.
1. Ficus Tuffi
Ficus Tuffi, often used as a pleached screen hedge, is a popular choice for gardens in New Zealand for its aesthetic appeal and practicality. This variety of Ficus is specifically cultivated for its dense, lush foliage and robust growth habit, making it ideal for creating privacy screens or hedges in both residential and commercial landscapes.
Conditions it thrives in
Ficus Tuffi prefers well-draining soil with a neutral to slightly acidic pH. It is adaptable to a range of soil types but flourishes in rich, fertile soils that are kept consistently moist. This plant does well in both full sun and partial shade but adequate sunlight is crucial for optimal growth and foliage density. It is suited to the temperate to subtropical climates found in many parts of New Zealand but is not as frost-tolerant as some other garden plants, so it thrives best in areas where frost is rare or mild.
Growth rate and size
Ficus Tuffi is known for its moderate to fast growth rate, depending on the growing conditions. With adequate care and optimal conditions, it can grow robustly at about 50-60 cm per year.
As a pleached screen or hedge, its size is often controlled through pruning. However, if left to grow naturally, it can reach significant heights. Regular trimming will keep it at the desired height and width, which is typically around 2-3 metres tall when maintained as a hedge or screen for privacy.
2. Prunus Lusitanica (Portugal Laurel)
Prunus Lusitanica, or Portugal Laurel, is a versatile evergreen tree or shrub with a glossy green leathery foliage, and the ability to be shaped through pruning. It's a popular choice for hedges and screens in New Zealand and can also be used as a feature plant. Prunus Lusitanica bears small, fragrant white flowers in spring, followed by red berries that mature to black, adding seasonal interest to gardens.
Conditions it thrives in
Portugal Laurel prefers well-drained soils enriched with organic matter but is adaptable to a wide range of soil types, including clay, loam, and sand, provided they are not waterlogged. It grows well in full sun to partial shade but more sunlight encourages better flowering and denser foliage. It is quite hardy and can tolerate a range of climates, from cool to temperate. It is frost-hardy, making it suitable for colder areas in New Zealand.
Growth rate and size
Portugal Laurel has a growth rate of around 30-60 cm per year, depending on growing conditions and care. It can reach heights of up to 6-8 metres if left unpruned, with a similar spread. However, its size is easily managed with pruning, and it is often kept much smaller in garden settings, especially when used as a hedge or screen.
3. Pittosporum Green Lustre
Pittosporum Green Lustre is a cultivar of Pittosporum, a genus of evergreen shrubs that are highly valued in New Zealand gardens for their attractive foliage, versatile landscaping use, and overall hardiness. Green Lustre is particularly noted for its vibrant green, glossy leaves that form a dense, rounded bush, making it an excellent choice for hedges, screens, and as a foundation plant in garden designs.
Conditions it thrives in
Pittosporum prefers well-drained soils but is quite adaptable to a range of soil types, from sandy to clay. Like many Pittosporum species, Green Lustre can tolerate somewhat poor soils, although it performs best in moderately fertile soil. While full sun encourages more dense and vigorous growth, it will also do well in partly shaded conditions. It is also suited to the temperate climate found in many parts of New Zealand. In coastal areas, it shows good tolerance to salt spray, making it a good choice for seaside gardens.
Growth rate and size
Pittosporum Green Lustre can grow around 30-40 cm per year with proper care. It typically reaches a height of 2-3 metres and can spread similarly, depending on pruning and local growing conditions. Its natural shape is rounded and dense, making it ideal for hedging.

4. Magnolia Grandiflora 'Blanchard'
Magnolia Grandiflora 'Blanchard' is highly regarded and known for its large, dark green glossy leaves with a striking brownish-bronze underside and its fragrant, creamy-white flowers. This particular cultivar stands out for its more compact growth habit and its ability to produce flowers at a younger age compared to other varieties of Magnolia Grandiflora. It's an excellent choice for gardens in New Zealand where a striking evergreen specimen tree with year-round interest is desired.

Growth rate and size
Cabbage trees can grow up to 1 metre per year in ideal conditions. They typically reach heights of 5-10 metres, with some specimens growing taller. The trunk may also branch out, leading to a multi-headed appearance.
10. Cupressocyparis Leylandii (Green Leylandii)
Cupressocyparis Leylandii, commonly known as Green Leylandii, is a fast-growing, evergreen conifer that is widely used for creating quick, effective hedges and screens. A hybrid between Cupressus Macrocarpa (Monterey Cypress) and Chamaecyparis Nootkatensis (Nootka Cypress), Leylandii combines the best traits of its parent species, including rapid growth and a dense, conical form.
