Another fast-growing native Australian tree is the Acacia Podalyriifolia, or Silver Wattle, known for its silvery foliage and bright yellow flowers. Wattles are short-lived trees with a lifespan of 7-12 years, but they grow rapidly, adding 0.5-1 meter of growth annually. The Blackwood, or Acacia melanoxylon, is another Acacia tree that shoots up to 30 meters tall and bears sweet-smelling yellow flowers. The Banksia integrifolia, or Coast Banksia, is a hardy, fast-growing tree with cylindrical flowers in shades of yellow or orange that attract native birds.

It has feathery leaves that resemble fern plants and vibrant flowers, thriving in sunny spots with well-drained soil.

Other fast-growing native Australian trees include the Australian Willow, known for its weeping form and slender, drooping branches; the Bottle Tree, which is recognised for its bulbous trunk and star-shaped flowers; the Paperbark Tree, which has papery bark and creamy white flowers; and the Black Sheoak, which provides excellent shade and windbreaks with its needle-like foliage and slender form.

Blueberry ash is a small tree or tall shrub that thrives in sandy or loamy soils, with full sun to partial shade. It can grow to be about 3m wide and 10m-15m high.

The weeping lily pilly is another graceful, evergreen tree known for its drooping branches and glossy, dark green leaves. It features lush, “weeping” foliage and grows up to 7–8 metres. It produces clusters of white flowers followed by pink berries, making it a favourite for ornamental planting and hedging.

Drought-tolerant trees

The Australian Willow is not a true willow, but its weeping form can easily deceive. It is a compact tree with slender, drooping branches that host lance-shaped leaves. It can be grown as a stand-alone specimen or pruned into a hedge. This tree thrives with deep watering sessions in its early stages and a sunny position.

The Bottle Tree is native to Australia and is renowned for its bulbous trunk, which resembles a bottle. It can be an interesting focal point, especially when it blooms with star-shaped flowers. It thrives in full sun and can adapt to a variety of soil conditions.

The Lemon Scented Gum (Eucalyptus Citriodora) is a statement tree with a smooth white trunk, creamy white flowers, and a beautiful lemon fragrance. It grows to an impressive height of 20-30 metres.

The Olive Tree, native to the Mediterranean, is a popular, low-maintenance option for areas with long, hot summers and cool winters. Common varieties planted in Australia include Kalamata, Manzanillo, and Frantoio, which produce delicious black or green olives or wonderful olives for oil-making.

Wattle trees are also excellent drought-tolerant options, with their silvery green-blue foliage and vibrant yellow blossoms. The Acacia Spectabilis (Mudgee Wattle or Glory Wattle) and Acacia Macradenia (Zig-zag Wattle) are native to New South Wales and Queensland, respectively, while the Acacia Podalyriifolia (Queensland Silver Wattle) is native to Queensland and grows to a height of seven metres.

The Bottle Tree is native to Australia and is known for its bulbous trunk. It thrives in full sun and various soil conditions. The Illawarra Flame is drought-tolerant but benefits from occasional watering. The Gum Tree is indigenous to Australia and is known for its diverse features, including its bark, leaves, and flowers.

Other fast-growing native trees include the Dwarf Gum, which provides the benefits of a large gum tree without growing into a giant, and the Lilly Pilly, which comes in many varieties, from small shrubs to big trees.

The Native Hibiscus (Alyogyne huegelii) is another fast-growing native shrub or tree with hibiscus-like flowers.

The Forest Pansy or Purple Redbud variety of this tree grows to around five meters in height and should be planted in a protected garden rather than a pot. The Magnolia, with its glossy deep-green leaves and fragrant white flowers, is another exotic tree that grows in most conditions, even in coastal areas.
