Alsophila dealbata, synonym Cyathea dealbata, commonly known as the silver fern or silver tree-fern, is a species of medium-sized tree fern, endemic to New Zealand. The fern is usually recognisable by the silver-white colour of the under-surface of mature fronds. 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 metres (33 ft) or more. The crown is dense, and mature fronds tend to be about 4 metres (13 ft) 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 fern 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.

The fern has become one of the most widely recognized symbols of New Zealand, it is not an official national symbol.

Germination: It is important to sterilize the soil mix with boiling water before planting. Use a pot with holes so water can drain. When cool, sow spores on the surface of the mix. Watering should be done from the base only (from a bottom tray), as watering from the surface will bury the seeds and they cannot grow. Cover the pot with clear plastic, and keep in a well lit location as light is required for germination. Do not place in direct sun. The ferns can take weeks or months to germinate.
