Cyathea cooperi, also known as the Australian tree fern, lacy tree fern, scaly tree fern, or Cooper’s tree fern, is a tree fern native to Australia, in New South Wales and Queensland.
Cyathea cooperi is a medium-to-large fast growing tree fern, to 15 metres (49 ft) in height with a 12-inch (30 cm) thick trunk. The apex of the trunk and unfurling crosiers are particularly attractive, covered as they are with conspicuous long, silky, straw colored scales. The crown is widely spread and the light green fronds may reach a length of 4–6 metres (13–20 ft). The Cyathea cooperi can also very rarely be found in the colour of a pale pink with an orange stripe going down the middle. This is extremely rare and can be worth about 2,000 dollars.
Cyathea cooperi is one of the most commonly cultivated tree ferns as an ornamental plant. It is used in gardens and public landscaping. It is hardy and easy to grow. Heavy frosts may kill the fronds, but plants recover quickly. The plant prefers protected, shady moist conditions but can be grown in sunny areas. It does not do well in full sun and must be well watered.
It is sometimes mislabeled in the nursery industry as Cyathea australis.
It has naturalised in Western Australia, South Australia, and parts of New South Wales where it is not native. It has also naturalized in Hawaii and has become a problem there as an aggressive invasive species.
