Description

This fern is known to grow to heights of or more (though it occasionally takes a rare creeping form). The crown is dense, and mature fronds can be as much as long and wide with a silver-white colouration on the undersides. The fronds may be bipinnately compound or tripinnate. The underside colouration is less intensely silvery or patchy in younger plants and juveniles are pale green. 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.

Use in sport

The silver fern has been used as a symbol by New Zealand national sports teams, in various stylised forms, since it was first worn by players in the 1888–89 New Zealand Native football team which toured Britain. "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). National sport teams using the silver fern include: *

Controversy

In 1991, the New Zealand Rugby Football Union obtained trade marks for the name “All Blacks” and its own stylised fern, however the scope of the application was broader because they sought to register any 'fern'. In 2005, after a legal case lasting four years, the union failed in its bid to stop anyone else using any fern logo on any black jersey.
