This large tree fern is native to the eastern parts of Australia and can grow to heights of 5-6 meters. However, some specimens have been known to reach over 15 meters tall.

The Dicksonia Antarctica can spread up to 4 metres and features light green fronds that create a canopy from the top of the tree.

This fern requires plenty of water to thrive, and it is important to protect it from strong winds. It grows best in moist, well-drained soil.

Adiantum aethiopicum (Maidenhair)

The Maidenhair is a small, delicate fern that is native to a wide range of regions, including Africa, Australia, Norfolk Island, and New Zealand.

This fern thrives in moist soil and prefers a protected area. It can tolerate some sunlight so long the soil doesn’t dry out.

In addition to its attractive appearance, the Maidenhair fern is also known for its air-purifying properties. It is reportedly able to remove pollutants from the air, making it a popular choice for indoor gardens.

Cyathea cooperi is another popular Australian tree fern that grows to a height of 6m. This fast-growing tree fern is characterised by its slender trunk and delicate fronds, which will add a tropical touch to any garden.

It does best in part shade and requires regular watering to keep its roots moist. In its natural habitat, it is commonly found in tropical lowlands in Queensland and New South Wales.

If you’re looking to add a touch of the tropics to your garden, the Cyathea cooperi is a great choice.

This unique tree fern is known for its knobbly trunk, which sets it apart from other ferns. It’s also very hardy and can tolerate colder climates than other ferns.

Growing up to 20m, it’s also the tallest of the Australian ferns. In fact, Cyathea australis holds the Guinness World Record for the tallest fern.

This fern has large fronds that can grow up to 4m in length that form an umbrella-like shape from the top of the tree. It does best in part shade and like other ferns, requires regular watering to keep its roots moist.

In its natural habitat, it is commonly found all along the east coast of Australia, including in Tasmania. If you’re looking for a hardy tree fern to add to your garden, the Cyathea australis would make an impressive addition.
