15 Rounded Australian Native Bush Plants
1. Leptospermum laevigatum ‘Fore Shore’
Leptospermum laevigatum ‘Fore Shore’ (syn. ‘Foreshore’) is a compact, coastal tea tree cultivar selected for its resilience and tidy, low-growing form. It features soft grey-green foliage and a naturally dense, mounding habit, complemented by small white flowers in spring.
Growing to about 50 cm high and 1 metre wide, it functions beautifully as a specimen bush, low hedge, groundcover, or informal border. The naturally rounded shape requires little maintenance, though it responds well to light pruning.
True to its name, ‘Fore Shore’ is one of the most salt-resilient Australian native bush plants. It adapts well to harsh coastal and inland conditions, often spotted in seaside gardens, roadside verges, and other public spaces.
2. Casuarina glauca ‘Green Wave’
When speaking of naturally rounded Australian native bush plants, Casuarina glauca ‘Green Wave’ (syn. ‘Greenwave’) comes to mind. This plant is a compact cultivar of the swamp sheoak, selected for its soft, fine, lush, bright green foliage.
Unlike its taller parent species, ‘Green Wave’ maintains a tidy, rounded habit, with 1.5 – 2 metres in height and width, making it a standout feature in both formal and informal landscapes. Its needle-like foliage gives it a unique, almost conifer-like texture, contrasting beautifully with broadleaf plants.
Hardy and adaptable, ‘Green Wave’ thrives in a wide range of tough conditions, including poor soils, coastal exposure, and periods of drought. It is a great plant for erosion control with a vigorous root system.
3. Casuarina glauca ‘Cousin It’
Casuarina glauca ‘Cousin It’ is an unusual, rounded, low shrub or mounding groundcover prized for its dense, cascading, needle-like foliage. While not strictly a rounded upright shrub, the plant is famous for creating a circular, textural mat that appears dramatically contoured on the ground due to its soft, trailing stems.
The cultivar is playfully named for its resemblance to the long-haired character Cousin Itt from a television show. Typically growing to 15 – 30 cm tall and 1 metre wide, it works wonderfully as a feature plant or cascading groundcover on flat garden beds, rockeries, retaining wall edges, or containers.
Beyond its looks, Casuarina glauca ‘Cousin It’ is incredibly hardy. It is highly tolerant of drought, frost, poor soils, and coastal conditions. Adaptable and tough, this plant stands out among Australian native bush plants for its quirkiness, resilience, and uniqueness.
4. Leucophyta brownii (Cushion Bush)
Leucophyta brownii, commonly known as Cushion Bush or Silver Bush, is one of the most unusual Australian native bush plants with distinctive foliage colour and texture. The plant is renowned for its unique silvery appearance and dense, rounded form.
The fine, twiggy stems are covered in soft, silvery-grey foliage that gives the plant a sculptural appearance, while contrasting brilliantly with green plants. Small, yellow button-like flowers appear in late spring and summer, adding a subtle pop of contrast without disrupting its tidy shape.
Typically growing to around 0.5 – 1 metre high and wide, Leucophyta brownii forms a neat, dome-like mound, requiring little to no pruning to maintain shape. Highly tolerant of wind, salt spray, poor soils, and drought, Cushion Bush is perfect for coastal gardens and harsh exposed sites. The ‘Silver Nugget’ cultivar is a dwarf form that grows 50 cm high and wide at maturity.
5. Acmena smithii ‘Allyn Magic’
Lilly pillies are iconic Australian native bush plants widely used for hedging and screening. Acmena smithii ‘Allyn Magic’ is a highly compact lilly pilly, prized for its tidy growth habit and dense, rounded form.
The plant features dense, glossy foliage with bright orange, pink, and red colours during periods of new growth, adding dynamic seasonal interest.
Growing 0.6 – 1 metre in height and width, it holds its shape well with minimal trimming but also responds easily to light pruning for a more manicured look. Its compact size and consistent form are especially useful in small gardens or structured designs, where form and consistency matter.
6. Correa alba (White Correa)
Correa alba, or White Correa, is a hardy and attractive Australian native bush admired for its soft texture and coastal charm. It features rounded, grey-green leaves with a velvety underside and a profusion of white, star-shaped flowers from late autumn to spring.
Typically growing to around 1 to 1.5 metres high and wide, Correa alba forms a naturally rounded, compact shrub that requires minimal maintenance. It works beautifully in coastal-themed landscapes, where its subtle tones and fine texture create a sense of calm and cohesion.
Highly valued for its resilience, Correa alba thrives in full sun to part shade and tolerates challenging coastal conditions, poor soils, and periods of drought. It responds well to pruning, allowing for shaping into hedges or topiary.
7. Correa glabra (Rock Correa)
One of the toughest and most adaptable Australian native bush plants is Rock Correa. Unlike Correa alba, Correa glabra is more upright than spreading in form. It features aromatic, bright, lush green leaves and tubular, pendulous flowers that can be green, yellow, or red.
Correa glabra is known to form an excellent hedge or privacy screen, growing to around 2 metres in height and width at maturity. When grown as a specimen plant, it forms a dense, bushy shape that fits well into native, cottage, or low-maintenance garden designs.

‘Aussie Box’ and ‘Grey Box’ are similar in form. Both are stunning Australian native bush plants for low hedges, borders, containers, and mass plantings. ‘Aussie Box’ is larger, growing to about 60 – 80 cm high and wide. It also develops finer, greener foliage and distinctive mauve flowers, instead of white.
Like ‘Grey Box’, ‘Aussie Box’ is highly drought-tolerant, frost-hardy, and well-suited to coastal conditions. Westringia ‘Aussie Box’ is a resilient and refined plant that works beautifully across a diverse range of landscape styles
11. Westringia ‘Blue Gem’
Westringia ‘Blue Gem’ stands out among Australian native bush plants for its prolific, violet-blue flowers and dense, fine foliage. Growing to about 1 – 1.5 metres tall and wide, ‘Blue Gem’ has a rounded, but somewhat free-flowing habit.

14. Acacia cognata ‘Mini Cog’
Acacia cognata ‘Mini Cog’ is a compact cultivar of the popular Bower Wattle. It is valued for its neat, rounded habit, graceful, lush, emerald green foliage, lime green new growth, and soft, flowing form.
Compared to some larger Acacia cognata cultivars, this plant offers the same elegance on a more manageable scale, growing to around 1 metre in height and 1.5 metres in width, making it highly suitable for ornamental gardens.
Its slender, cascading foliage moves beautifully with the breeze, creating a delicate, dynamic texture. While not its primary feature, the cultivar produces small, pale yellow flowers in late winter.
15. Acacia cognata dwarf ‘Nano’
Acacia cognata dwarf ‘Nano’ is another rounded Australian native bush with a graceful form. True to its name, it is a miniature version of Acacia cognata that reaches only 50 cm in height and 60 cm – 1.2 m at maturity.
Compared with Acacia cognata ‘Bower Beauty’, ‘Nano’ often appears more compact and petite, rather than flowing. It develops brighter lime-green foliage without bronze new growth and produces only a light sprinkling of pale yellow, spherical flowers in late winter.
‘Nano’ is ideal for tight spaces where a uniform, structured look is desired in modern garden design. Its compact, tidy form makes it well suited to mass planting, low hedging, borders, or as a soft underplanting beneath taller shrubs and trees.
