Mamaku or Black Tree Fern   

Family: Cyatheaceae Genus:  Cyathea medullaris

Some call it also Black Ponga or King of the Tree Ferns

The tallest and fastest growing New Zealand tree fern. It can grow to 20 meters tall. It has a black trunk with very large fronds 2-6 meters long. A dramatic specimen plant that does not tolerate colder temperatures as well as some of the other varieties. It easily grows in a warmer climate.

It’s new fronds begin as tight black “curls”, and unfurl to produce a stunning, large umbrella canopy, with fronds reaching up to 6m in length.
