Pittosporum is a group of evergreen shrubs or small multi-stemmed trees that are popular hedge plants. Pittosporum shrubs have leathery green leaves with wavy margins that grow in whorls at branch ends. The dense evergreen foliage creates attractive screens, privacy barriers, hedgerows, or specimen plants. In colder climates, pittosporum bushes are ideal container plants that are easy to grow on a patio, deck, or at the front of house.
One of the beauties of pittosporum is that it’s a low-maintenance shrub and easy to grow in most garden landscapes. For example, a pittosporum hedge will thrive in zones 8 to 10. All the evergreen hedge needs is some light pruning to keep its shape, water during hot weather, and to ensure it grows in well-draining ground.
Apart from its ornamental glossy green leaves, the attractive features of pittosporum hedging plants are their white scented flowers, excellent growth rate, and ability to thrive in full sun or shade.
Pittosporum also goes by the common names Austrian laurel, mock orange, and Japanese pittosporum.
This article is a guide to the many types of pittosporums suitable for garden landscapes. You will also learn how to grow this tough bush as an attractive shrub to protect gardens. But, first, we will look at how to grow pittosporum shrubs as a beautiful ornamental hedge.
Pittosporum Hedge

Pittosporum shrubs are ideal as hedging plants because they grow fast, have dense evergreen foliage, and are easy to prune. In addition, Pittosporum hedge plants are very drought-tolerant, withstand salty air, and survive the heat. From all the popular hedge shrubs like Boxwood (Buxus), pittosporum is one of the fastest-growing plants for hedges.
The shrub’s attractive foliage makes pittosporum bushes popular as low-maintenance barriers or screens. Some pittosporum cultivars have variegated leaves with interesting shapes and textures. For example, Pittosporum tenuifolium ‘Golf Ball’ has bright green oval leaves. However, Pittosporum tobira ‘Variegata’ has spoon-shaped dull green leaves with creamy-white margins. Or there is the Pittosporum tenuifolium ‘Tom Thumb’—a dwarf hedging plant with purple leaves.
By planting a pittosporum hedge, you can grow a tall privacy screen in your backyard. Depending on the cultivar, the popular pittosporum shrubs grow between 8 and 13 ft. (2.4 – 4 m) high and up to 8 ft. (2.4 m) wide. However, suppose you want a low-growing hedge with dense evergreen foliage. In that case, a dwarf pittosporum is ideal as a shrub border.
How to grow pittosporum hedge

To grow a pittosporum hedge, plant the shrub in any type of well-draining soil. Plant in full sun or shade and only water during summer if the weather is particularly hot and dry. Add slow-release shrub fertilizer in spring to encourage healthy leaf growth.
When planting a pittosporum hedge in your garden landscape, space the plants around 3 ft. (1 m) apart. Pittosporum bushes spread between 6 and 8 ft. (1.8 – 2.4 m) wide. So, planting this way ensures that a dense privacy screen grows.
Trimming pittosporum hedge

Regularly trimming a pittosporum hedge every spring helps maintain its height and promote dense foliage growth. When trimming the hedge, avoid cutting back the pittosporum too much. Instead, in spring, trim off about one-half of new growth in the first two years.
From year three, start shaping the hedge and leave the base wider than the top. This ensures that sunlight reaches most of the foliage. Once the pittosporum hedge is at its required height, you can trim it closely to keep its shape and form.
If you notice dead branches or pink stems, you should cut infected limbs back to the main stem.
Variegated Pittosporum (Pittosporum variegata)
A pittosporum shrub with variegated leaves allows you to grow an attractive hedge with green and creamy-white leaves. Several species of pittosporum have variegated cultivars. Generally, the variegated pittosporum plants have ovate or obovate green leaves with narrow whitish or yellowish wavy margins.
Types of Pittosporum (With Pictures)
There are over 150 species of pittosporum shrubs and small trees in the family Pittosporaceae. Most pittosporum varieties are hardy in USDA zones 8 through 10. However, some variegated cultivars may only thrive in zones 9 and 10.
Let’s look in more detail at some of the most popular pittosporum hedging shrubs and plants.

Common Problems Growing Pittosporum Hedge
Pittosporum hedges are typically hard, pest and disease-free shrubs when grown in proper conditions. Usually, growing in well-drained soil and ensuring plenty of air circulation is enough to prevent any foliage fungal diseases.
Sometimes, pests such as mealybugs, aphids, or cottony cushion scale can affect the hedging shrubs. You can usually use a strong jet of water to remove the pests from the foliage physically. Other solutions for getting rid of pests from a pittosporum hedge include neem oil. However, a DIY neem oil solution may not be as practical for treating a large hedge as a sharp blast of water from a hose.
