Alsophila australis
Rough tree fern is a tall Australian tree fern with a massive trunk and a crown of large lacy fronds, often grown in cool, moist gardens and as a tub plant. The key to growing it is keeping humidity and moisture high while tolerating some sun in cooler areas.
Alsophila australis, synonym Cyathea australis, also known as the rough tree fern, is a species of tree fern native to southeastern Queensland, New South Wales and southern Victoria in Australia, as well as Tasmania and Norfolk Island.
It was known as beeow-wang in Illawarra, as pooeet at Corranderrk Station in Victoria, and as nanga-nanga in Queensland.
Alsophila australis is a robust tub plant and tolerant of salty winds. It is a popular cool climate hardy tree-fern, adaptable to a variety of climates and soils. It grows in moist shady forest, both coastal and montane, at an altitude up to 1,280 m (4,200 ft), often in the company of Dicksonia antarctica. It is a relatively hardy species and a popular landscape and container plant. Provided moisture levels remain high, it will tolerate frost and full sun, or shade in warmer regions. Although well known in its native country, this species is not common in cultivation outside of Australia.
