Cyathea dealbata, also known as the silver tree-fern or silver fern, or as ponga /ˈpɒŋə/ or punga /ˈpʌŋə/ (from Māori kaponga or ponga), is a species of medium-sized tree fern, endemic to New Zealand. It is a symbol commonly associated with the country both overseas and by New Zealanders themselves.
This fern is known to grow to heights of 10 m or more (though it occasionally takes a rare creeping form). The crown is dense, and the fronds tend to be about 4 m long and have a silver-white colouration on the undersides. This distinctive silver colouration has made them useful for laying along tracks for night walking. The scales are a dark brown and are often twisted and glossy.
Arriving relatively late in New Zealand's history during the Pliocene epoch (around 5.0–1.8 million years ago), the silver fern occurs on the main islands of New Zealand and on the Chatham Islands to the east, mostly in the subcanopy areas of drier forests and in open scrub. It is known to grow well in well-drained humus, and once established, it will tolerate drier conditions. It does best when sheltered from winds and should be protected from frost.
In short, the fern has become one of the most widely recognised symbols of New Zealand, next to the Kiwi, though it is not an official symbol.
The silver fern is widely used as a symbol by New Zealand national sports teams in various stylised forms. "Silver Ferns" is the name of the national netball team, and most other national women's sports teams have nicknames based on the term "Ferns", such as Black Ferns (women's rugby union), Tall Ferns (women's basketball) and Football Ferns (women's association football).
