Best-known tree fern from Australia, with a massive red brown to dark brown trunk, that is 4-5 m and sometimes reaching 10-15 m.
The leaves are middle to dark green and 4.5 m long. Young fronds are a shade lighter of colour.
It has a great adaptability to various circumstances, which makes it clear why it is often seen in cultivation.
It responds best to a mild and moist environment.
Placed on a sunny location it is in need of more water compared to more shady circumstances.
In good conditions the tree fern grows approx. 3 cm each year.
This is a very-cold hardy tree fern -10°C.
It can be planted in the garden but it has to be covered at -5°C with straw and a rush-mat.
Make sure the roots are protected by leaves, straw or other available materials.
