Hedges are excellent for privacy, defining the boundary of your property, and can even be used to create different ‘garden rooms’ in your yard.
A hedge does take a little time to establish, so the plants you choose should reflect how quickly you want the hedge to grow and how often you want to trim it.
Although there are a variety of great low-maintenance hedge plants that you can select from, bear in mind that all hedges do require some maintenance because they have to be trimmed on a regular basis to keep their shape.
Here’s a selection of our top picks for low-maintenance hedge plants to grow in Australia:
Orange Jasmine (Murraya paniculata)
Murrayas are popular hedging plants, especially in warmer climates.
In addition to their lovely green foliage, they also produce gorgeous white flowers in spring, summer, and autumn. These plants have a lovely citrusy fragrance.
For a tall hedge, murrayas will easily grow to a height of around 2 to 3 metres and can be well-maintained at this height.
However, if you want to grow a much lower hedge, there are also dwarf varieties available that will work equally as well.
To get a nice dense hedge, you want to space the plants around 50 cm to 1 metre apart.
Remember to keep the plants watered well until they become fully established.
Fertiliser should be applied in early spring and again in autumn to keep your plants nice and lush.
- A lovely dense hedge with the added advantage of lovely citrus-scented flowers.
- Suitable for most climates but needs extra water during hot and dry conditions and protection from frosts.
- Adaptable to different soil types but does require good drainage.
- Non-toxic to humans or animals.
- The berries are attractive to birds, while bees and butterflies love the flowers.
- Takes around 3 to 4 years to grow to full height.

Photinia ‘Red Robin’
In southern parts of the country, photinia is a very popular hedging plant.
It not only lends itself to creating a lovely, dense hedge but also adds a little extra colour to your garden with its attractive new red growth.
With photinia, you can easily grow a tall hedge that reaches a height of 3 to 4 metres.
Space the plants about 60 cm to 80 cm apart to ensure good dense coverage.
You only need to fertilise once in spring with a slow-release fertiliser.
- A fast grower that will put on 30 cm of growth every year.
- Has lovely glossy green leaves and dark red new growth.
- Will respond to heavy pruning to get them back in shape.
- The small white flowers have an unpleasant fragrance but winter pruning should inhibit flower growth.
- Needs to be trimmed every 4 to 6 weeks during active growth.
Sweet Viburnum (Viburnum odoratissimum)
Sweet viburnum is another popular hedging plant, especially for gardeners in temperate, coastal, and subtropical climates.
It produces large glossy green leaves and small fragrant white flowers.
It’s ideal for large hedges and can grow to a height of around 3 to 4 metres.
Plants should be spaced around 1 metre apart as they can easily spread to around 2 to 3 metres in width.

Lilly Pilly (Acmena smithii)
Lilly pillies are great low-maintenance Australian native plants that are perfect for hedging.
They are more suitable for areas with a more temperate climate.
However, if you protect them from frosts while young, they can be grown successfully in southern areas as well.
Not only do Lilly pillies have attractive foliage with lovely new red growth but they also produce edible fruits that are quite popular for making into jams. Of course, the birds love these fruits too.
Lilly pillies can grow into large trees reaching a height of around 6 metres.
However, they are quite happy to be trimmed and pruned to a more suitable height.
Space your hedge plants around 1 metre apart to get a nice dense hedge.
Fertilise with a slow-release fertiliser once a year in spring.

Coastal Rosemary only needs to be fed once a year with a slow-release fertiliser in spring.

Many gardeners will be familiar with the common box hedges that are found all over the world.
However, for Australian conditions, the Japanese Box is much more suitable as it can handle warmer temperatures.
This plant has small green leaves that are quite glossy. It lends itself really well to hedging and also shaping into topiaries.

Feed the plants with a slow-release fertiliser in spring and autumn.

To keep it under control, it needs to be pruned at least twice a year due to its fast growth.
However, other than regular pruning, this plant requires very little else to keep it growing well.
You might want to apply a slow-release fertiliser once a year in spring to keep it nice and green.
Space plants around 1 metre apart when growing as a hedge.
- Excellent screening plant with a fast growth habit.
