Australian Tree Fern (Cyathea cooperi), also known as the Lacy Tree Fern, is a medium-to-large, fast growing tree fern native to Australia.

This fern grows to 15 m in height with a 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 m.

Cultivation

This is one of the most commonly grown tree ferns used in gardens and commercial landscaping. It is hardy and easy to grow. Heavy frosts may kill the fronds, but plants recover quickly. They prefer protected, shady moist conditions but can be grown in sunny areas. It does not do well in full sun.

It has naturalized in Hawaii and is a major problem there, being seen as an invasive species.

This plant is also known as the Scaly Tree Fern and Cooper’s Tree Fern.
